Ya weird. I set the whole extend in the ExecuteInformation routine as per
the <br>
documentation. Should it be set somewhere else? <br><br>

obtained by the reader's output's whole extent. The reader or the module
do not have to provide anything for this to work. Is your reader setting
the whole extent properly?<br><br>

<dd>Hello again,<br><br>
<dd>I was able to figure out how to create a new reader for paraview. The
problem I<br>
<dd>described in my previous message went away when I used the
correct<br>
<dd>vtkTypeMacro. I am able to use the new reader to get data into
paraview and <br>
<dd>do a few things with it.<br><br>
<dd>One thing that does not seem to work is the ExtractGrid filter. When
I try to<br>
<dd>use this filter with my data the VOI min and max values are all
large<br>
<dd>negative numbers. My reader creates a structured points data set. How
does <br>
<dd>the ExtractGrid filter get<br>
<dd>the data extents from the upstream data source in paraview? I have
looked<br>
<dd>at other<br>
<dd>reader code in paraview like the plot3d reader and there does not
seem to<br>
<dd>be any<br>
<dd>special magic that I can find. <br><br>
<dd>Thanks,<br>

<dd>>Hello,<br>
<dd>><br>
<dd>>I am trying to add a new reader to paraview. I am using paraview
version<br>
<dd>>2.2.1 on a<br>
<dd>>Fedora Core 2.0 linux distro. Paraview builds fine. I am
following the <br>
<dd>>instructions in<br>
<dd>>the paraview guide version 1.8 and the instructions in the
PVLocal<br>
<dd>>directory. I was<br>
<dd>>able to compile the "local cone source" example. When I
import the package<br>
<dd>>into <br>
<dd>>paraview it works fine.<br>
<dd>><br>
<dd>>As a first step, I wrote a new reader and tested it in VTK. The
new reader<br>
<dd>>builds a structured points dataset. I then copied the new reader
.h and<br>
<dd>>.cxx file into the <br>
<dd>>PVLocal directory and made the recommended changes in the Cmake
and xml<br>
<dd>>files. I also included the required config files in my .cxx file.
I am<br>
<dd>>able to compile the<br>
<dd>>new reader and create a shared library but the shared library has
an undefined <br>
<dd>>symbol corresponding to my reader. Paraview does not like that.
When I<br>
<dd>>try to import the package I get an error. I have included the
header file<br>
<dd>>for my<br>
<dd>>reader and the two xml files with this message. If anyone sees
what I am doing <br>
<dd>>wrong a hint would be greatly appreciated.<br>
<dd>><br>
