Burlen/ Aashish/ B.W.H,
I haven’t been following this thread, but just a note that there is a bug already written about this code, and a similar (but not exact) error.  Said bug report is here:   http://www.paraview.org/Bug/view.php?id=15020  It is slated to be fixed in a minor release within the next few months.

You could try it without modifying any code by setting  the following cmake variable.

VTK_IGNORE_GLDRIVER_BUGS:BOOL=ON

and recompile ParaView. With my ATI Radeon HD7780 projected tetrahedra just hangs.

Looks like certain extensions are still not quite working on yours system even with the proprietary driver. I will see if I can run your code on my laptop but that would be for tomorrow.

** Assuming that this is not data dependent issue (which it should not).

I think its probably this line causing the issue:


bool
                  driverSupport










 #if
                    defined(__APPLE__)











                  = true;











                    #else











                  = !(extensions->DriverIsATI()











                  &&
                  (extensions->GetDriverGLVersionMajor() >= 3))











                  || extensions->GetIgnoreDriverBugs("ATI texturing bug");











                    #endif














On line number 181: can you change this code to :

this->HasHardwareSupport
          =
          renwin
          !=
          NULL
          &&
          this->IsSupported(renwin);
to
this->HasHardwareSupport
          =
            1;

Progress indeed. But I don't understand what you are saying about the transfer function.

I' starting to wonder if I have two issues occurring simultaneously.
In a new thread I just posted I described my problem in getting the colours in place.
I need to write to a vtk file first and load it back.  I just found that when I just did that
and then switched fo volume rendering, an error was there about the absence
of an opengl extension:

ERROR: In /usr/local/git/ParaView/VTK/Rendering/VolumeOpenGL/vtkOpenGLProjectedTetrahedraMapper.cxx, line 185
vtkOpenGLProjectedTetrahedraMapper (0x58ae490): The required extensions are not supported.

 This is complete unknown terrain for me.

progress!  it sounds like volume rendering is working on the wavelet dataset.

You do need the scalars for volume rendering, so make sure you have those when you try. You need to select the scalars in the drop down also, I usually do this before changing to the volume representation. You also may need to edit the transfer function. For testing you could make the opacity over the entire scalar range in which case you should see a solid cube.

If you've done all that and don't see anything it's likely that the dataset is messed up.  Add a dataset->Print(cerr) statement to the end of your request data,  look in the information panel and verify correct number of points and scalar ranges.

If all else fails post the dataset to the list. After creating your cube go to the file menu and "save data".

Hi Burlen,

I have upgraded to the AMD drivers. Thanks for the hint. It has improved the situation a bit.

Furthermore, I created the wavelet source. When selecting "volume" representation, I do see a three 3 picture, in all 5 volume rendering mode (smart, raycast and texture mapping, ray cast only, texture mapping only, GPU based). The picture a rather fuzzy, but then I don't know what I'm supposed to see here. The good news is that the openGL errors I had before when displaying a wavelet, now have gone.

The situation with my own cube, though, has unchanged. unfortunately.
The cube disappears in "volume" representation node, also when I  re-inserted scalar values for each of the 8 vertices.

Hi Bertwim,

In recent releases of ParaView I have experienced issues/flakeyness with volume rendering. Something you should try: Create the wavelet source, then in the properties panel find "volume rendering mode" and set it to "ray cast only".  This has worked for me on a number of systems. may or may not work, but worth a try.

The output you pasted below shows that although you've got a sweet ATI GPU you're not taking advantage of it! You're using the Intel integrated GPU with Mesa drivers. If I were you I would install proprietary the AMD drivers<http://support.amd.com/en-us/download>. This should give you nice performance boost and may even solve the OpenGL errors you reported, which these days are as often (or more) a result of bugs in the Mesa drivers than in VTK.

Hi Aashish,

This is what I do:
1. start paraview
2. Sources -> Wavelet -> Apply.
     A cube is displayed (Outline representation).
3. Select 'Volume" representation"

cube disappears. Then:
=====================

So when you created a wavelet source and change the representation to volume you got the errors? Can you post those errors?

Thanks,

Aashish,

Thanks for the suggestion.

However, doing this gives me all kinds of opengl errors (invalid instruction).

Besides that, the wavelet gives me a cube indeed, but I need to understand when
I can have a volume rendering. I created new Source's (e.g. tri-prism, a wedge,
a box with boundaries of finite thickness etc.). But I cannot get volume rendering
to work, grrrrrr. (See other thread)

Kind Regards,
Bertwim

Can perhaps somebody point me how to address the following.

When I create a new source (say: a box) I get an a box that
can be displayed via its surfaces, its constituing points, or wireframe
representation.
But I need a volume rendering (so that I can add e.g. a clipping plane)
How do I get that?

Bertwim
