Utkarsh/ Cory,
Why wasn't Anti-Aliasing turned on by default on PV 5.2.0?  Wasn't that the plan?  I assume we need to make sure it gets turned on by default...

Thanks,

Alan

Last minute I decided to punt on making FXAA the default as it showed
some issues with SurfaceLIC. Also, the way we were thinking, to turn
it on without affecting testing was going to be unnecessarily
complicated. Since we were changing all baselines when the new scalar
bar changes land (ETA, Cory?), it would have been a better time to
change the default.

Good job on the 5.2.0 release team!  Here is feedback from one of my power users:

Sources/ Ruler has been enhanced - Yay!
A generic Edit/ Reload Files menu option has been added - Yay!
Anti-aliasing for lines is available through Edit/ Settings/  Render View / Use FXAA - Yay!
Hidden line removal has been enhanced and is now available. - Yay!

Thanks for working to get these improvements in there,

Subject: ParaView 5.2.0 release

ParaView 5.2.0 has been released by Kitware and is now installed and the is default here at Sandia on the SRN and SCN LANs. ParaView is a scientific visualization application installed at Sandia.

Standalone installs for, Windows, OS X and Linux are being worked on, and will be available for download within a week.

ParaView 5.2.0 is medium level upgrade, with the following enhancements that stand out to me.

Sources/ Ruler has been enhanced, allowing users to measure distances between points or cells.  Try turning on Auto Apply, and the ruler will automatically update.  Also, hitting the number 1 sets the beginning placement for the ruler, 2 sets the ending point for the ruler.  There are also many improvements still to come with this tool.

A generic Edit/ Reload Files menu option has been added.  This works on all readers.

Anti-aliasing for lines is available through Edit/ Settings/  Render View / Use FXAA.  This works local and remote server.  I hope to have this turned on by default soon.

Hidden line removal has been enhanced and is now available.  Find this at the bottom of the Properties tab - Hidden Line Removal.  Test with Sources/ Wavelet, then render with Wireframe.  This fails on large data, remote server, which is why it is turned off by default.

Kitware's release notes for 5.2.0 are located here:  https://blog.kitware.com/paraview-5-2-0-release-notes/, as well as through the ParaView help menu.

Thanks,

Alan

Subject: [Paraview-developers] ROS experience ?
Message-ID: <CANMN6xjfhuVmyfvQnpkDLQYtkvpo8oohS=JPqMLKJum-J5RXQg@mail.gmail.com>

Hello Folks,

TL;DR: Have you ever used ROS [1] within a Kitware project ?

Kitware has been contacted recently by companies looking for joint Computer
Vision + Robotic applications. Topics like SLAM, or object detection and
grabbing have showed up, and ROS could be a good starting point.
I hear about ROS for many years, and former academic colleagues at ETH
Zurich were using it and contributing to it, but I never did.
ROS is similar to OpenCv, but much more oriented towards realtime robotics.
ROS (Robot Operating System) [1] is pretty popular in the robotics
community. It's basically a middle ware to transfer all kinds of data (such
as point clouds, image-flow, depthmaps, odometry, ...). ROS repository then
provides lots of other algorithms, named "packages".
The core is BSD-licensed, and many packages also are.

I guess it should not be too difficult to write IO wrapper to/from VTK/PV
to enable further visualization (e.g., the bounding boxes or the resulting
cloud). Maybe providing a live VTK source that gets ROS-based point-cloud.
Has anyone played around in this direction ? Is that the right way to go?

The new scalar bar is coming along. Some text rendering changes
necessitated some baseline changes that I am working through now. Then
I'll add a test with Alan's list of ranges to test that he sent me a
while and work through that. Then we should be ready. I wouldn't merge
until after a 5.2.1 is tagged, though.

Thanks Cory - your scalar bar was on my list, but we ran out of time.  Good to hear, let me know when I can start testing.

OK, to be clear.  Our fix will be rolled at in a 5.2.1 tag, and we will put new Linux binaries out on the website?  Or, replace all downloads?

Alan,

Apologies, I should have said "next ParaView release" instead of
5.2.1! There are no *firm* plans as of now for a 5.2.1 release. Let's
fix [1] first and then we'll determine whether a patch release will be
made before 5.3.

Sorry for the confusion!

Message-ID: <c67254f8275c449c8f506bff4d680d5b@RZJMBX1.jr1.local>

Hi

I programmed successfully a plugin source wich generates a vtkImageData output and made it the same way as on my 3d cloud plugins of vtkPolyData. The source is inherited from vtkImageAlgorithm and only contains one output with unsigned char array and one component. 

In the request data function of the filter I currently have a very dummy:

output->SetDimensions(oData.imgSizeX, oData.imgSizeY, 1);
output ->AllocateScalars(VTK_UNSIGNED_CHAR, 1);
 memcpy(output ->GetScalarPointer(), &oData.imgData[0], oData.imgSizeX* oData.imgSizeY*sizeof(unsigned char));

in paraview I see in the information tab that  I have an uniform rectilinear grid with 1917201 cells and 1920000 points (image is 1600*1200px). In data Arrays I get an "ImageScalars" of unsigned char and a correct range of my memcopy data (my min max range is not 0,255 so data seems to be there)...

the problem is that I cannot see anything in the render view, any suggestions what I am making wrong? I tested all representation (slice, surface, outline, on Solid Color and on my array), never see anything.....

I also compared the Information tab on a loaded jpeg image and cannot see any difference (which is rendered in render view except the Array's string name), by the way: can I disable "MapScalars" by default?

I am using pv5.2

Hi Gerald,

Not sure it is the only issue but please try giving a name to the output
scalar arrays.
ParaView won't make visible arrays which don't have a name.
Example:
  output->GetPointData()->GetScalars()->SetName("values");

Best,

Mac and Linux both uploaded 3 hours ago around 11.

I see the last build uploaded is on the 29th. It seems to be failing on
HDF5 errors (updating the common superbuild will fix that).

Mac and Linux now seem to show start times of 1/1/1970 this afternoon
instead of 12/23|29/2016 as it did this morning.

Hi

Good try but does not effect anything except the string in paraview?s combo box. The strange thing is that I also cannot see anything in spreadsheet view (empty cell and point data)? but on information tab point data and cell data is there?.

Hi Gerald,
Not sure it is the only issue but please try giving a name to the output scalar arrays.
ParaView won't make visible arrays which don't have a name.
Example:
  output->GetPointData()->GetScalars()->SetName("values");

Hi

I programmed successfully a plugin source wich generates a vtkImageData output and made it the same way as on my 3d cloud plugins of vtkPolyData. The source is inherited from vtkImageAlgorithm and only contains one output with unsigned char array and one component.

In the request data function of the filter I currently have a very dummy:

output->SetDimensions(oData.imgSizeX, oData.imgSizeY, 1);
output ->AllocateScalars(VTK_UNSIGNED_CHAR, 1);
 memcpy(output ->GetScalarPointer(), &oData.imgData[0], oData.imgSizeX* oData.imgSizeY*sizeof(unsigned char));

in paraview I see in the information tab that  I have an uniform rectilinear grid with 1917201 cells and 1920000 points (image is 1600*1200px). In data Arrays I get an "ImageScalars" of unsigned char and a correct range of my memcopy data (my min max range is not 0,255 so data seems to be there)...

the problem is that I cannot see anything in the render view, any suggestions what I am making wrong? I tested all representation (slice, surface, outline, on Solid Color and on my array), never see anything.....

I also compared the Information tab on a loaded jpeg image and cannot see any difference (which is rendered in render view except the Array's string name), by the way: can I disable "MapScalars" by default?

I am using pv5.2

Hmm sorry if I had took a closer look I would have seen that
AllocateScalars set a default name "ImageScalars" to the scalar array.
Then don't know what you did but the print says that the name of your array
is "21745593" which is quite strange. Is it what you did?

Could you write your "output" image data to a .VTI file using a
vtkXMLImageDataWriter after initializing it in your RequestData
function and see if you can load in with PV and view it? Share it if you
can't.

Sorry for my late reply:

?21745593? is correct, that?s the UID string of the sensor/camera which generates the vtkImagedata, I set the string from its SDK?. I will try writing the vti file for you?.

Hmm sorry if I had took a closer look I would have seen that AllocateScalars set a default name "ImageScalars" to the scalar array.
Then don't know what you did but the print says that the name of your array is "21745593" which is quite strange. Is it what you did?
Could you write your "output" image data to a .VTI file using a vtkXMLImageDataWriter after initializing it in your RequestData
function and see if you can load in with PV and view it? Share it if you can't.

Good try but does not effect anything except the string in paraview?s combo box. The strange thing is that I also cannot see anything in spreadsheet view (empty cell and point data)? but on information tab point data and cell data is there?.

Hi Gerald,
Not sure it is the only issue but please try giving a name to the output scalar arrays.
ParaView won't make visible arrays which don't have a name.
Example:
  output->GetPointData()->GetScalars()->SetName("values");

Hi

I programmed successfully a plugin source wich generates a vtkImageData output and made it the same way as on my 3d cloud plugins of vtkPolyData. The source is inherited from vtkImageAlgorithm and only contains one output with unsigned char array and one component.

In the request data function of the filter I currently have a very dummy:

output->SetDimensions(oData.imgSizeX, oData.imgSizeY, 1);
output ->AllocateScalars(VTK_UNSIGNED_CHAR, 1);
 memcpy(output ->GetScalarPointer(), &oData.imgData[0], oData.imgSizeX* oData.imgSizeY*sizeof(unsigned char));

in paraview I see in the information tab that  I have an uniform rectilinear grid with 1917201 cells and 1920000 points (image is 1600*1200px). In data Arrays I get an "ImageScalars" of unsigned char and a correct range of my memcopy data (my min max range is not 0,255 so data seems to be there)...

the problem is that I cannot see anything in the render view, any suggestions what I am making wrong? I tested all representation (slice, surface, outline, on Solid Color and on my array), never see anything.....

I also compared the Information tab on a loaded jpeg image and cannot see any difference (which is rendered in render view except the Array's string name), by the way: can I disable "MapScalars" by default?

I am using pv5.2

Hi Steven,

Thanks for the code submission! I've asked Sebastien Jourdain to review it
on Gitlab directly since he seems to have written most of that class.

Cheers,
Andy

When we use paraview with MPI, does it uses CUDA aware MPI or simple MPI
implementations like OpenMPI / MPICH?

It uses whichever one it is compiled against. The release binaries on
the website use mpich2.

Subject: [Paraview-developers] Migration plugin from pqNamedObjectPanel to
	pqPropertyWidget
Message-ID: <41b2f79df0c54b67975012d7bb92d08e@RZJMBX1.jr1.local>

Hi 

I am migrating my plugins from pqNamedObjectPanel to new pqPropertyWidget. I have 2 unsolved taskes in one of my more complicated filters left which I cannot figure out how to solve:

First Problem:

I have a small getterfunction with a text of my plugin filter which includes some information about the processing (computation time and a kind of fitness score during computation) wich I displayed in my old plugin widget of pqNamedObjectPanel in the overloaded updateInformationAndDomains() function:

void
pqMyFilter::updateInformationAndDomains()
{
    if(!this->proxy())
    {
        return;
    }

    vtkSMPropertyHelper oGetInfo(this->proxy(), "GetInfo");
    oGetInfo.UpdateValueFromServer();

    m_poInformation->setText( QString(oGetInfo.GetAsString()));
}


How can I do that with pqPropertyWidget? Or is there a better way (maybe somehow to bring it into the "Information" Tab instead of property tab....)

Second Problem:
I programmed a Attribute Array QTreeView of a certain kind of attributes of my inputs with checkboxes ( I only allow selection of attributes which are in all inputs). I already integrated it that it loads dynamically everything correct in constructor, but I miss a possibility of a callback/Qt Signal when input changes so that I can update that list..... any suggestions? In my old plugin I used

QObject::connect( proxy, SIGNAL( producerChanged(const QString&) ),
                      this, SLOT( updateMyList() ), Qt::QueuedConnection ); 

of the pqProxy proxy, but  now we use vtkSMProxy which does not have a producerChanged signal, any suggestions?

thanks

There's no reason it can't; ParaView will use whatever MPI you've built it
against.  The binaries on the parview.org website are built against MPICH
with TCP so If you want to use a high performance interconnect, i.e.
InfiniBand, then you'll want to build your own ParaView and provide it the
appropriate MPI libraries, which in your case, would also be built to
support direct GPU RDMA.

OK. That's weired, your VTI is correct.
And what if you save the output of your filter/reader with ParaView "Save
Data"? Is data correctly saved and reloaded correctly?

Nope, the data is then nearly empty (<1kByte), hiere the vti writer output:

OK. That's weired, your VTI is correct.
And what if you save the output of your filter/reader with ParaView "Save Data"? Is data correctly saved and reloaded correctly?

i have uploaded the vti onto
https://expirebox.com/download/60e7c1e8d177f282ae90d42f75e5ae50.html
the link is 48h accessible
?
when I load the vti into paraview everything is visualized correctly

Sorry for my late reply:
?
?21745593? is correct, that?s the UID string of the sensor/camera which generates the vtkImagedata, I set the string from its SDK?. I will try writing the vti file for you?.

Hmm sorry if I had took a closer look I would have seen that AllocateScalars set a default name "ImageScalars" to the scalar array.
Then don't know what you did but the print says that the name of your array is "21745593" which is quite strange. Is it what you did?
Could you write your "output" image data to a .VTI file using a vtkXMLImageDataWriter after initializing it in your RequestData
function and see if you can load in with PV and view it? Share it if you can't.

Hi
?
Good try but does not effect anything except the string in paraview?s combo box. The strange thing is that I also cannot see anything in spreadsheet view (empty cell and point data)? but on information tab point data and cell data is there?.

Hi Gerald,
Not sure it is the only issue but please try giving a name to the output scalar arrays.
ParaView won't make visible arrays which don't have a name.
Example:
? output->GetPointData()->GetScalars()->SetName("values");
Best,

Hi

I programmed successfully a plugin source wich generates a vtkImageData output and made it the same way as on my 3d cloud plugins of vtkPolyData. The source is inherited from vtkImageAlgorithm and only contains one output with unsigned char array and one component.

In the request data function of the filter I currently have a very dummy:

output->SetDimensions(oData.imgSizeX, oData.imgSizeY, 1);
output ->AllocateScalars(VTK_UNSIGNED_CHAR, 1);
?memcpy(output ->GetScalarPointer(), &oData.imgData[0], oData.imgSizeX* oData.imgSizeY*sizeof(unsigned char));

in paraview I see in the information tab that? I have an uniform rectilinear grid with 1917201 cells and 1920000 points (image is 1600*1200px). In data Arrays I get an "ImageScalars" of unsigned char and a correct range of my memcopy data (my min max range is not 0,255 so data seems to be there)...

the problem is that I cannot see anything in the render view, any suggestions what I am making wrong? I tested all representation (slice, surface, outline, on Solid Color and on my array), never see anything.....

I also compared the Information tab on a loaded jpeg image and cannot see any difference (which is rendered in render view except the Array's string name), by the way: can I disable "MapScalars" by default?

I am using pv5.2

Could you share the code of your reader? If you prefer you can remove all
specific stuff and keep only VTK related stuff.
I would like to see how exactly you fetch the output grid to fill and how
your filter defines its output.

Just wanted to add that so far, no existing ParaView features can take
benefit of CUDA-aware MPI,
only simple MPI is used.
However you should be able to use it if you want to use it in your own
plugins (parallels readers/filters).

Subject: [Paraview-developers] Question about custom paraview data
	server/source
Message-ID: <CAKDaRuLemjO=U__Hv-RHnK-W28-Z689BxH2Re_G1NNe-MDD81g@mail.gmail.com>

Hi,

I would like to implement something that sends data (triangle mesh with
normals and colors) in "real time" from a C++ application to a Paraview
client running on the same machine, to help debugging. By "real time" I
mean that I am only interested in the latest data, not in the history of it.

Currently, I can repeatedly save vtk files in my application, and hit F5 in
Paraview to reload the file and get pretty much the effect that I want. I
am looking for a way to automate.

I have read some of the documentation about custom servers and started
writing something based on pvserver sources, but I am not sure I'm going on
the right direction. In particular, I don't want to do any custom
rendering, but I am not entirely sure that writing only a data server (ie
using the builtin renderer) is possible.

I have a feeling that this should not be difficult to implement, do you
know of any better approaches?

Thank you,
-- Giovanni

Hi

I uploaded a cleaned version of the reader without gui component to https://expirebox.com/download/b5db956fb2b0787ac16ef9b42e46698a.html (again 48h available). The GUI has included a timer which polls on the HasNewData() function and if it returns true it forces an update of the request data function.  I copied that workflow of the PCLPlugin of Paraview of the Kinect OpenNI Source?.. the commented code also displays the *.vti writing....

Best regards,
Gerald

Could you share the code of your reader? If you prefer you can remove all specific stuff and keep only VTK related stuff.
I would like to see how exactly you fetch the output grid to fill and how your filter defines its output.

OK. That's weired, your VTI is correct.
And what if you save the output of your filter/reader with ParaView "Save Data"? Is data correctly saved and reloaded correctly?

Hmm sorry if I had took a closer look I would have seen that AllocateScalars set a default name "ImageScalars" to the scalar array.
Then don't know what you did but the print says that the name of your array is "21745593" which is quite strange. Is it what you did?
Could you write your "output" image data to a .VTI file using a vtkXMLImageDataWriter after initializing it in your RequestData
function and see if you can load in with PV and view it? Share it if you can't.

Good try but does not effect anything except the string in paraview?s combo box. The strange thing is that I also cannot see anything in spreadsheet view (empty cell and point data)? but on information tab point data and cell data is there?.

Hi Gerald,
Not sure it is the only issue but please try giving a name to the output scalar arrays.
ParaView won't make visible arrays which don't have a name.
Example:
? output->GetPointData()->GetScalars()->SetName("values");

Hi

I programmed successfully a plugin source wich generates a vtkImageData output and made it the same way as on my 3d cloud plugins of vtkPolyData. The source is inherited from vtkImageAlgorithm and only contains one output with unsigned char array and one component.

In the request data function of the filter I currently have a very dummy:

output->SetDimensions(oData.imgSizeX, oData.imgSizeY, 1);
output ->AllocateScalars(VTK_UNSIGNED_CHAR, 1);
?memcpy(output ->GetScalarPointer(), &oData.imgData[0], oData.imgSizeX* oData.imgSizeY*sizeof(unsigned char));

in paraview I see in the information tab that? I have an uniform rectilinear grid with 1917201 cells and 1920000 points (image is 1600*1200px). In data Arrays I get an "ImageScalars" of unsigned char and a correct range of my memcopy data (my min max range is not 0,255 so data seems to be there)...

the problem is that I cannot see anything in the render view, any suggestions what I am making wrong? I tested all representation (slice, surface, outline, on Solid Color and on my array), never see anything.....

I also compared the Information tab on a loaded jpeg image and cannot see any difference (which is rendered in render view except the Array's string name), by the way: can I disable "MapScalars" by default?

I am using pv5.2

Subject: [Paraview-developers] ParaView and Qt 5
Message-ID: <CADHSJjCs7J3ynCrErE5A42L2zwxFzT6EKLggOQ2K-6=dxPpp=g@mail.gmail.com>

Folks,

With upcoming release (5.3), we plan to move to using Qt 5 by default.
Qt 5 has been out since 2012 and it is well supported on modern
platforms. ParaView will continue to build with Qt 4 until further
notice, but we highly recommend custom application developers and
plugin developers to move to Qt 5 at the earliest since active
development and testing for ParaView will happen with Qt 5.

Changes [1] that landed in master earlier today update ParaView to now
use QOpenGLWidget for rendering which creates a frame buffer object to
do all the rendering in. If you have custom mapper or rendering code
that assumed it was rendering to the default onscreen frame buffer, it
will not work correctly and will need to be updated. Please use the
mailing, if you encounter any such issues. For everything else, the
changes should be fairly transparent except in exceptions documented
here [2].

In the upcoming weeks, we will update the superbuild and dashboards to
build and test using Qt 5.

Thanks,
Utkarsh

Gerald,

I think there is the problem with this:
if (!this->HasNewData())
  return 1;

It means that most of the time, the filter will return an empty output.
Instead, you should cache (retain a pointer off oLatest as member variable)
the last image and ShallowCopy it to the output in this case.

Something like:

    if (this->HasNewData())
    {
        this->OLatest = this->m_poInternal->GetLatestImageData();
    }

    if (this->OLatest)
        poOutput->ShallowCopy(this->OLatest);

Here's a summary:

There's a fix in master.

We are going to tag 5.2.1 with patches here:
https://gitlab.kitware.com/paraview/paraview/merge_requests/1288
This simply reverts the change that introduced the bug. The fix in
master adds more code changes that I don't feel comfortable adding on
the release branch without more testing.

5.2.1 may happen simultaneously with 5.3 RCs, Whether sites deploy
5.2.1 or directly 5.3 is deferred to site admins.

Good idea, I made some tests:

if (this->HasNewData())
{
this->OLatest = this->m_poInternal->GetLatestImageData();
}
else
{
vtkErrorMacro(?You should never came here?);
}

I also tested to set a member variable vtkSmartPointer<vtkImageData> myTempImage; to the class (like you mentioned) and store it everytime so that output gets always ShallowCopied regardless to the HasNewData, but no effect. The HasNewData is always true because I call this function from my GUI panel and only force an update if that function returns true, so it would be strange if that would not work?..

I have the exact same workflow in my  vtkPolyData source which works perfectly? I really don?t know why this does not work?. I copied the workflow from the PointCloud plugin?. (OpenNISource)

I also made now a minimalistic test and changed my requestdata function to:

 vtkInformation *outInfo = outputVector->GetInformationObject(0);
vtkImageData *    output = vtkImageData::SafeDownCast(outInfo ->Get(vtkDataObject::DATA_OBJECT()));


    vtkSmartPointer<vtkImageData> imageData = vtkSmartPointer<vtkImageData>::New();
    imageData ->SetDimensions(10, 10, 1);

    imageData ->AllocateScalars(VTK_FLOAT, 1);
    memset(imageData ->GetScalarPointer(), 0, 10*10*sizeof(float));
    output ->ShallowCopy(imageData);

same behaviour?.

Another failed try:

   output ->SetDimensions(10, 10, 1);

    output ->AllocateScalars(VTK_FLOAT, 1);
    memset(output ->GetScalarPointer(), 0, 10 * 10 * sizeof(float));



By the way: why dows paraview say that images are rectilinear grid's? My output is a vtkImageData which does not seem to be inherited from rectilinear grid.... also when I load images normally into paraview I get rectilinear grids as output..... should I program a rectilinear grid output filter?

Gerald,

I think there is the problem with this:
if (!this->HasNewData())
? return 1;
It means that most of the time, the filter will return an empty output.
Instead, you should cache (retain a pointer off oLatest as member variable) the last image and ShallowCopy it to the output in this case.
Something like:

??? if (this->HasNewData())
??? {
??????? this->OLatest = this->m_poInternal->GetLatestImageData();
??? }

??? if (this->OLatest)
??????? poOutput->ShallowCopy(this->OLatest);

Best,

Hi

I uploaded a cleaned version of the reader without gui component to https://expirebox.com/download/b5db956fb2b0787ac16ef9b42e46698a.html (again 48h available). The GUI has included a timer which polls on the HasNewData() function and if it returns true it forces an update of the request data function.? I copied that workflow of the PCLPlugin of Paraview of the Kinect OpenNI Source?.. the commented code also displays the *.vti writing....

Best regards,
Gerald

Could you share the code of your reader? If you prefer you can remove all specific stuff and keep only VTK related stuff.
I would like to see how exactly you fetch the output grid to fill and how your filter defines its output.

OK. That's weired, your VTI is correct.
And what if you save the output of your filter/reader with ParaView "Save Data"? Is data correctly saved and reloaded correctly?

Hmm sorry if I had took a closer look I would have seen that AllocateScalars set a default name "ImageScalars" to the scalar array.
Then don't know what you did but the print says that the name of your array is "21745593" which is quite strange. Is it what you did?
Could you write your "output" image data to a .VTI file using a vtkXMLImageDataWriter after initializing it in your RequestData
function and see if you can load in with PV and view it? Share it if you can't.

Hi

I programmed successfully a plugin source wich generates a vtkImageData output and made it the same way as on my 3d cloud plugins of vtkPolyData. The source is inherited from vtkImageAlgorithm and only contains one output with unsigned char array and one component.

In the request data function of the filter I currently have a very dummy:

output->SetDimensions(oData.imgSizeX, oData.imgSizeY, 1);
output ->AllocateScalars(VTK_UNSIGNED_CHAR, 1);
?memcpy(output ->GetScalarPointer(), &oData.imgData[0], oData.imgSizeX* oData.imgSizeY*sizeof(unsigned char));

in paraview I see in the information tab that? I have an uniform rectilinear grid with 1917201 cells and 1920000 points (image is 1600*1200px). In data Arrays I get an "ImageScalars" of unsigned char and a correct range of my memcopy data (my min max range is not 0,255 so data seems to be there)...

the problem is that I cannot see anything in the render view, any suggestions what I am making wrong? I tested all representation (slice, surface, outline, on Solid Color and on my array), never see anything.....

I also compared the Information tab on a loaded jpeg image and cannot see any difference (which is rendered in render view except the Array's string name), by the way: can I disable "MapScalars" by default?

I am using pv5.2

I now have it (but don?t know why, an explanation would be great), my solution was deleting RequestData and using same pipeline as copied from vtkJPEGReader/vtkImageReader2 with request information:

int vtkROSImageSource::RequestInformation(
    vtkInformation       * vtkNotUsed(request),
    vtkInformationVector** vtkNotUsed(inputVector),
    vtkInformationVector * outputVector)
{
vtkSmartPointer<vtkImageData> latest = this->m_poInternal->GetLatestImageData();

    if (latest)
    {
        this->DataExtent[0] = oLatest->GetExtent()[0];
        this->DataExtent[1] = oLatest->GetExtent()[1];
        this->DataExtent[2] = oLatest->GetExtent()[2];
        this->DataExtent[3] = oLatest->GetExtent()[3];
        this->DataExtent[4] = oLatest->GetExtent()[4];
        this->DataExtent[5] = oLatest->GetExtent()[5];

        this->SetDataScalarType(latest ->GetScalarType());
        this->SetNumberOfScalarComponents(latest ->GetNumberOfScalarComponents());

        // get the info objects
        vtkInformation* outInfo = outputVector->GetInformationObject(0);
        outInfo->Set(vtkStreamingDemandDrivenPipeline::WHOLE_EXTENT(),
            this->DataExtent, 6);
        outInfo->Set(vtkDataObject::SPACING(), this->DataSpacing, 3);
        outInfo->Set(vtkDataObject::ORIGIN(), this->DataOrigin, 3);

        vtkDataObject::SetPointDataActiveScalarInfo(outInfo, this->DataScalarType,
            this->NumberOfScalarComponents);

        outInfo->Set(CAN_PRODUCE_SUB_EXTENT(), 1);
    }
    return 1;
}

void vtkROSImageSource::ExecuteDataWithInformation(vtkDataObject *output,
    vtkInformation *outInfo)
{
    vtkImageData *data = this->AllocateOutputData(output, outInfo);

    vtkSmartPointer<vtkImageData> latest = this->m_poInternal->GetLatestImageData();

    if(latest)
    {
        data->ShallowCopy(latest);
    }
}

The only thing which is bad is that paraview does use "SolidColor" as default with "Outline" Representation. I have to switch to my scalar name and "Slice" representation manually, any hints how to do that automatically? Would also like to turn off "MapScalars" by default...

Betreff: AW: [Paraview-developers] [Paraview] vtkImageData Plugin, vtkImageData not rendered

Good idea, I made some tests:

if (this->HasNewData())
{
this->OLatest = this->m_poInternal->GetLatestImageData();
}
else
{
vtkErrorMacro(?You should never came here?); }

I also tested to set a member variable vtkSmartPointer<vtkImageData> myTempImage; to the class (like you mentioned) and store it everytime so that output gets always ShallowCopied regardless to the HasNewData, but no effect. The HasNewData is always true because I call this function from my GUI panel and only force an update if that function returns true, so it would be strange if that would not work?..

I have the exact same workflow in my  vtkPolyData source which works perfectly? I really don?t know why this does not work?. I copied the workflow from the PointCloud plugin?. (OpenNISource)

I also made now a minimalistic test and changed my requestdata function to:

 vtkInformation *outInfo = outputVector->GetInformationObject(0);
vtkImageData *    output = vtkImageData::SafeDownCast(outInfo ->Get(vtkDataObject::DATA_OBJECT()));


    vtkSmartPointer<vtkImageData> imageData = vtkSmartPointer<vtkImageData>::New();
    imageData ->SetDimensions(10, 10, 1);

    imageData ->AllocateScalars(VTK_FLOAT, 1);
    memset(imageData ->GetScalarPointer(), 0, 10*10*sizeof(float));
    output ->ShallowCopy(imageData);

same behaviour?.

Another failed try:

   output ->SetDimensions(10, 10, 1);

    output ->AllocateScalars(VTK_FLOAT, 1);
    memset(output ->GetScalarPointer(), 0, 10 * 10 * sizeof(float));



By the way: why dows paraview say that images are rectilinear grid's? My output is a vtkImageData which does not seem to be inherited from rectilinear grid.... also when I load images normally into paraview I get rectilinear grids as output..... should I program a rectilinear grid output filter?

Gerald,

I think there is the problem with this:
if (!this->HasNewData())
? return 1;
It means that most of the time, the filter will return an empty output.
Instead, you should cache (retain a pointer off oLatest as member variable) the last image and ShallowCopy it to the output in this case.
Something like:

??? if (this->HasNewData())
??? {
??????? this->OLatest = this->m_poInternal->GetLatestImageData();
??? }

??? if (this->OLatest)
??????? poOutput->ShallowCopy(this->OLatest);

Best,

Hi

I uploaded a cleaned version of the reader without gui component to https://expirebox.com/download/b5db956fb2b0787ac16ef9b42e46698a.html (again 48h available). The GUI has included a timer which polls on the HasNewData() function and if it returns true it forces an update of the request data function.? I copied that workflow of the PCLPlugin of Paraview of the Kinect OpenNI Source?.. the commented code also displays the *.vti writing....

Best regards,
Gerald

Could you share the code of your reader? If you prefer you can remove all specific stuff and keep only VTK related stuff.
I would like to see how exactly you fetch the output grid to fill and how your filter defines its output.

OK. That's weired, your VTI is correct.
And what if you save the output of your filter/reader with ParaView "Save Data"? Is data correctly saved and reloaded correctly?

in paraview I see in the information tab that? I have an uniform rectilinear grid with 1917201 cells and 1920000 points (image is 1600*1200px). In data Arrays I get an "ImageScalars" of unsigned char and a correct range of my memcopy data (my min max range is not 0,255 so data seems to be there)...

the problem is that I cannot see anything in the render view, any suggestions what I am making wrong? I tested all representation (slice, surface, outline, on Solid Color and on my array), never see anything.....

I also compared the Information tab on a loaded jpeg image and cannot see any difference (which is rendered in render view except the Array's string name), by the way: can I disable "MapScalars" by default?

I am using pv5.2

Subject: [Paraview-developers] How can I get a proper vtk reader class from
 a filename with extension

Hi Paraviewers,

Got a bit of a challenge here.

I'm trying to create a plugin with a custom reader, that is subclass of a vtkMetaReader, so it can read any file via readers registered with ParaView.

All the implementations I saw use a If statement:

https://github.com/Kitware/ParaView/blob/b41d27999a4ac854f4a0e61d98d09c53e7583a60/ParaViewCore/ClientServerCore/Default/vtkNetworkImageSource.cxx

But I would like to have something in sync with the available readers.

For now I use something similar to:

const char *readerName = readerFactory->GetReaderName();
vtkObject *object = vtkObjectFactory::CreateInstance( readerName );[https://www.upwork.com/messages/rooms/room_38bea0513672a1d805f45ad03c83519e]

But for a .PNG file I receive as readerName "vtkImageFileSeriesReader" instead of "vtkPNGReader".

So basically my question is:

How can I get a proper vtk reader class from a filename with extension?

Thank you very much,

Subject: [Paraview-developers] Where does the vtkSelection come from?
Message-ID: <CACqg2jfJPtN5Z7A7Pv6TDdEm0kmcAV8fd6orBYtKACPjPxTvQA@mail.gmail.com>

All day I am already struggling now with some possibly very "simple"
problem: I am trying to write a filter that applies some operations only to
selected cells of an "unstructured grid".

I am taking the "extract selection" filter as an example. This filter takes
the "data" stuff at input port 0 and a vtkSelection object at input port 1,
then does the proper processing. However, from a user perspective the
filter is attached to one single input data set with selections. Like
exactly the unstructured grid with some cells selected: I can easily
extract them with the "extract selection" filter - and I do not have to
specify a second data item for input port 1!

But if I am simulating exactly the code in the server XML (specifying two
input ports, for "input" and "selection"), then copying all the relevant
stuff from the cxx files of vtkPVExtractSelection.cxx,
vtkExtractSelection.cxx and vtkExtractSelecitonBase.cxx - I do not get the
same behaviour!

Instead I am getting exactly what I would have expected otherwise: my
filter asks for a second input data item - but what should I choose? And
then it stops because indeed it does not find any vtkSelection data object
at port 1.

While the latter looks somehow logical to me I still wonder how the extract
seleciton filter does the apparent "magic" of having that selection object
at port 1 for further processing!

Any hint where I should have a look into the code, or what else I might
have forgotten?

As I said I simulated the server XML and the cxx code, but now I guess that
maybe there are still other places in the code where I should have a look??

Thanks in advance for any helpful hints!
Cornelis

Message-ID: <CADHSJjBExV6N8MFwOJ0YC=FwkC629oJ4Ks+gQuUb+7=nYYpL3Q@mail.gmail.com>

Folks,

Two new dashboards are now "expected". These are on "tylo" (Windows)
and "vall" (Linux). These test ParaView OpenGL2 with Qt 5 and Python 3
support.

While current master (v5.2.0-223-ge77fa66) has two
`CatalystLiveSetBreakpoint` tests failing, this MR [1]  should address
that.

In coming weeks, we will continue converting Qt 4 dashboards to test
with Qt 5 instead. We will still have 1 or 2 dashboards testing with
Qt 4 until we decide to remove support for it.

In all honestly, this is not easy to pull off. Readers in VTK don't have
consistent API, as a result it's going to be very tricky to expose
properties on this new meta-reader that can work across all readers.

The problem you're specifically facing is that readers like PNGReader (and
several others) use meta-readers themselves to support things that the
original reader doesn't support e.g. reader file series. Also,
`vtkSMReaderFactory::GetReaderName` returns the name for the reader proxy,
not the class name for the reader.

The vtkSelection comes from a "Selection Source" proxy that ParaView
internally creates that defines the selection. sources.xml [1] defines
several types of selection sources, e.g. ThresholdSelectionSource,
IDSelectionSource, SelectionQuerySource.

To make your filter behave like the "Extract Selection" filter where
it automatically sets up the selection, make sure you have the
<SelectionInput> hint [2].

Thanks Utkarsh,

It looks like these were the final hints that made it happen for me!

First the "hints" entry really did the "magic" I was looking for.

And second I am using now a vtkPVSelectExtraction filter (inside my own
filter) for converting all the different types of selection into all cell
indices for easy further processing.

Overall I am getting the impression that these "Hints" are covering still a
lot more "magic" that is worth discovering... ;-)

Regards,
Cornelis

Thank you Utkarsh for your answer.

We choose a IF Statement implementation for now.

Subject: Re: [Paraview-developers] How can I get a proper vtk reader class from a filename with extension

In all honestly, this is not easy to pull off. Readers in VTK don't have consistent API, as a result it's going to be very tricky to expose properties on this new meta-reader that can work across all readers.

The problem you're specifically facing is that readers like PNGReader (and several others) use meta-readers themselves to support things that the original reader doesn't support e.g. reader file series. Also, `vtkSMReaderFactory::GetReaderName` returns the name for the reader proxy, not the class name for the reader.

Hi Paraviewers,

Got a bit of a challenge here.

I?m trying to create a plugin with a custom reader, that is subclass of a vtkMetaReader, so it can read any file via readers registered with ParaView.

All the implementations I saw use a If statement:

https://github.com/Kitware/ParaView/blob/b41d27999a4ac854f4a0e61d98d09c53e7583a60/ParaViewCore/ClientServerCore/Default/vtkNetworkImageSource.cxx

But I would like to have something in sync with the available readers.

For now I use something similar to:

const char *readerName = readerFactory->GetReaderName();
vtkObject *object = vtkObjectFactory::CreateInstance( readerName );[https://www.upwork.com/messages/rooms/room_38bea0513672a1d805f45ad03c83519e]

But for a .PNG file I receive as readerName ?vtkImageFileSeriesReader? instead of "vtkPNGReader".

So basically my question is:

How can I get a proper vtk reader class from a filename with extension?

Thank you very much,

Jonathan Borduas

I'm trying to compile a paraview using a Qt5 (5.7.1) that I've compiled with '-qt-xcb' to avoid too many dependencies. When compiling paraview (git version), I supposed that the following would be sufficient to convey which qt to use:

cmake -DPARAVIEW_BUILD_QT_GUI=ON -DQT_QMAKE_EXECUTABLE:FILEPATH=/software/path/qt-5.7.1/bin/qmake -DPARAVIEW_QT_VERSION:STRING=5  ...

However, the find_package(Qt5) locates the system Qt and its cmake file, which bombs out:

CMake Error at CMake/ParaViewQt.cmake:65 (find_package):
  Could not find a configuration file for package "Qt5" that is compatible
  with requested version "5.6".
  The following configuration files were considered but not accepted:
    /usr/lib64/cmake/Qt5/Qt5Config.cmake, version: 5.5.1
    /usr/lib64/cmake/Qt5/Qt5Config.cmake, version: 5.5.1
Call Stack (most recent call first):
  Qt/Widgets/CMakeLists.txt:200 (pv_find_package_qt)


Which config variables am I missing?

Thanks,

Subject: [Paraview] ParaView and Qt 5

Folks,

With upcoming release (5.3), we plan to move to using Qt 5 by default.
Qt 5 has been out since 2012 and it is well supported on modern
platforms. ParaView will continue to build with Qt 4 until further
notice, but we highly recommend custom application developers and
plugin developers to move to Qt 5 at the earliest since active
development and testing for ParaView will happen with Qt 5.

Changes [1] that landed in master earlier today update ParaView to now
use QOpenGLWidget for rendering which creates a frame buffer object to
do all the rendering in. If you have custom mapper or rendering code
that assumed it was rendering to the default onscreen frame buffer, it
will not work correctly and will need to be updated. Please use the
mailing, if you encounter any such issues. For everything else, the
changes should be fairly transparent except in exceptions documented
here [2].

In the upcoming weeks, we will update the superbuild and dashboards to
build and test using Qt 5.

Thanks,
Utkarsh

Hi Mark,

CMake uses different variables to find Qt4 vs Qt5.  QT_QMAKE_EXECUTABLE is
the Qt4 variable and is ignored by the code to find Qt5.  The variable you
want is: -DQt5_DIR=/software/path/qt-5.7.1/lib/cmake/Qt5

Hi,

I would like to create a plugin that uses h5py and numpy to read a file, do
some operations on it and return VTK objects.
Would it be possible to do the same thing as
http://www.paraview.org/Wiki/Animating_legacy_VTK_file_series#Making_custom_readers_work_with_file_series
but instead of using a vtkPDataSetReader use a vtkPythonProgrammableSource?

I have made a (very naive) try, attached to this post.
When using this to read a series of files I get the errors (version 5.2.0
64-bit) shown below.
To test, just use any hdf5 file. (.h5)

Thanks for any help,
Daan

Message-ID: <20170119161928.GA26876@megas.kitware.com>

Hi,

I recently changed the CDash link that buildbot constructs to be based
on the revision rather than the name of the build and an "after" filter.
However, it turns out CDash that has an implicit "today" filter in there
which causes the results shown to change over time. After talking with
Zack about it, a plain revision query shouldn't have an implicit date
range associated with it, so once the fix is deployed (hopefully today),
the links will work again as intended.

Until then, you can add a "Build Start Time" "is before" "now" filter to
get all of the builds.

Sorry for the disruption,

Hello,

We develop a custom plugin for ParaView which we like to distribute as a 
shared library along with the official ParaView binaries (from 
http://www.paraview.org/download/).

This worked fine up to ParaView 5.1.x, using Debian 6 as mentioned on
http://www.paraview.org/Wiki/ParaView/Binaries#Linux-x64.
Updating to ParaView 5.2, I encounter various problems on Debian Squeeze 
(6):
  - python >= 2.7 required
  - freetype needs pkg-conf only available from Debian Wheezy (7)

What is the official build system for Linux binaries of ParaView 5.2?

Thanks,
Florian

Hi

You will need to use the ParaView-Superbuild, but it is not an easy process.

You can also contact us (Kitware) to do it for you.

Regards

Hello,

We develop a custom plugin for ParaView which we like to distribute as a
shared library along with the official ParaView binaries (from
http://www.paraview.org/download/).

This worked fine up to ParaView 5.1.x, using Debian 6 as mentioned on
http://www.paraview.org/Wiki/ParaView/Binaries#Linux-x64.
Updating to ParaView 5.2, I encounter various problems on Debian Squeeze
(6):
 - python >= 2.7 required
 - freetype needs pkg-conf only available from Debian Wheezy (7)

What is the official build system for Linux binaries of ParaView 5.2?

Thanks,
Florian

Hello Mathieu,

Thanks, for the reply.

Yes, we are using the superbuild where we include our plugin as an 
External plugin. This works fine, however the generated packages (via 
`ctest -R cpack`) are not transferable to different Linux distributions 
(e.g. build on Ubuntu16.04 does not work on Centos7.2 due to different 
versions of system C++ libraries).
Additionally, the generated shared libraries of our plugin cannot be 
combined with the official binaries by copying them over to the 
appropriate library directory (results in segfault when loading the plugin).

This used to work on ParaView 5.1.x when the plugin was built on Debian 
6 using the build options given on 
http://www.paraview.org/Wiki/ParaView/Binaries#Linux-x64. As it does not 
work with 5.2 any more, I assumed the build environment changed. 
Unfortunately, I cannot find any information about the build environment 
for 5.2. Is there any information available?

Kind regards,
Florian

We needed to upgrade to CentOS 6 in order to support the OpenGL2 backend
(and Qt5 compilation). We are using the devtoolset-3 SCL (see this
list[1]). We tried to use a more modern Debian (7 IIRC), but that put us
ahead of what CentOS 6 could run out-of-the-box, so we used CentOS 6
instead.

I'll look at updating that page.

Subject: [Paraview-developers] Adding CGNS as thirdparty to ParaView
Message-ID: <CADHSJjAHp2Od_WinOHboDHHCd+e9TP6kRAsf0DaVxwOt6QWaAQ@mail.gmail.com>

Folks,

Given that there is an increasing interest in using CGNS with ParaView
and that it's quite tedious to build with an external CGNS, I am
wondering if we should consider adding CGNS as a third-party library
to ParaView source itself.

Wondering if anyone has any thoughts on that?

Thanks

Daan,

Can you try changing the `si_class` attribute in the XML for the proxy to
be `vtkSIMetaReaderProxy`? I suspect the classname was changed at some
point. If that works, I can update the Wiki.

Thanks
Utkarsh

Hi Utkarsh,

When I do that I get a segfault, with the following backtrace:

Daan,

I didn't notice this earlier, but you're using a vtkProgrammableFilter
together with a vtkFileSeriesReader. That, I am afraid is not current
supported. You're better off adding support to reading the multiple files
to your Programamble Source itself. The ParaView guide does provide an
example for a reading a file series of csv files as a time series (Section
13.2.2). That should give you pointers to update your Python script. Let me
know if you need additional pointers.

Hi Utkarsh,

I think I can make that work. Is there any way to get a filename pattern
(or list of files) in a nice way through the GUI?

Also I'm having trouble accessing the Properties set in my script when
using it with python_filter_generator.py

Hi Utkarsh,

I managed to fix all of the aforementioned. There is just one problem left,
when I import h5py.
There is no h5py included in the paraview python installation, right? I'm
not married to this specific module, so alternatives are also okay.

ImportError: /usr/lib/python2.7/site-packages/h5py/_errors.so: undefined
symbol: PyUnicodeUCS4_DecodeUTF8
Traceback (most recent call last):
  File "<string>", line 20, in <module>
  File "<string>", line 1510, in RequestData
  File "/usr/lib/python2.7/site-packages/h5py/__init__.py", line 24, in
<module>
    from . import _errors

See also:
http://stackoverflow.com/questions/16871799/trying-to-import-a-module-undefined-symbol-pyunicodeucs4-decodeutf8
This means that the paraview included python installation is UCS2, which is
incompatible with my local version.

Do you have a suggestion for where on the wiki to document the
fileseriesreader I have built?

Daan

Message-ID: <CAA7GnUnhpV7m74_m1aj8PcYSNyN4iZbe4rK837xiW2BFt+vVRA@mail.gmail.com>

Hello ParaView community,

ParaView provides various image compression configuration options
<http://www.paraview.org/Wiki/ParaView/Image_Compressor_Configuration>. I
was wondering how to go about scripting this so that I can test setting
various parameters in a script.

I did check some of ParaView modules but couldn't find anything helpful.

Any pointers from anyone would be helpful.

Best,

Moving to paraview-developers

You mean add the functionality to the ply reader, or generic to all readers?

This is for David Peterson, the person on the phone call last week.  I think he has a short term (i.e., next week) need and a long term (future work) need.

Alan and Utkarsh,

I'm confused. Is this the same feature as reading a series of PLY
files as a time series where each PLY file represents one time step?
Isn't that supported already?

If it is a different feature, what do you mean by time slice?

Thanks,
Cory

You are correct, I am using sloppy terminology (as usual).

I believe we have the ability to write PLY time series, but not read PLY time series.  My user wants to read, not write.

My best guess would be to try to trace the save screenshot functionality, and see what is set.  Sorry, that?s the best I have...

Hello ParaView community,

ParaView provides various image compression configuration options<http://www.paraview.org/Wiki/ParaView/Image_Compressor_Configuration>. I was wondering how to go about scripting this so that I can test setting various parameters in a script.

I did check some of ParaView modules but couldn't find anything helpful.

Any pointers from anyone would be helpful.

Subject: [Paraview-developers] ParaView 5.3 RC1 will be tagged Friday,
	February 10
Message-ID: <CAB5Fpx7Un_+vo0ifVJ2MKfsUFBFTVNnKxT=KtCNHHstA-ocZ7g@mail.gmail.com>

ParaView developers,

We are planning to start the ParaView 5.3 release process by tagging
ParaView 5.3 RC1 on Friday, February 10, 2017. Please get any merge
requests you would like to see in 5.3 merged by then if possible.

As in prior releases, we will likely have several release candidates,
so opportunities for additional bug fixes in 5.3 will still be
available after February 10. The ParaView 5.3 final release is set to
be tagged on March 3, 2017.

Thanks,
Cory

Subject: [Paraview-developers] paraviewweb WebGL
Message-ID: <14B6A68F-44DE-4BE6-B2CD-4852C01FEA89@allenmuse.com>

I am currently using the <VtkRenderer> React component to display .pvd and .vtu files.  Is it possible for the VtkRenderer to display these files using WebGL, or do I need to use a different renderer to display these files using WebGL, like the <GeometryRenderer> component?

In the old version of ParaViewWeb, we specified the renderer in vtkWeb.Viewport.createViewport().

We are looking for the smoothest/most performant way to display these files with ParaViewWeb.

Thanks,
Dave

Hi Dave,

There is no current implementation that will deal with WebGL rendering
using a ParaViewWeb server.
We aim to use vtk-js for it, but we still need to build a client component
and a server side protocol.
And I have no time scale for when those will be available.

As for now, you can still use the old JavaScript code as we still have the
server side endpoints.

But if you can't wait and need those components sooner, you can always fund
us to build them via a support contracts or else.

Seb

Subject: [Paraview-developers] Buildbots migrated to Qt5
Message-ID: <20170131203811.GA18716@megas.kitware.com>

Hi all,

Nearly all of the dashboards which test the GUI are now testing Qt5
(ista and bigmac are the exceptions). Since lots of builder names were
changing anyways, we took the chance to change builders from:

    +opengl2 -> nothing (assumed)
    +qt5 -> nothing (assumed)

and builders doing either the old OpenGL backend or Qt4 now explicitly
have:

    +opengl1
    +qt4

in their build names.
