Progress indeed. But I don't understand what you are saying about
the transfer function.<br>
<br>
I' starting to wonder if I have two issues occurring simultaneously.<br>
In a new thread I just posted I described my problem in getting the
colours in place.<br>
I need to write to a vtk file first and load it back. I just found
that when I just did that<br>
and then switched fo volume rendering, an error was there about the
absence<br>
of an opengl extension:<br>
<br>
ERROR: In
/usr/local/git/ParaView/VTK/Rendering/VolumeOpenGL/vtkOpenGLProjectedTetrahedraMapper.cxx,
line 185<br>
vtkOpenGLProjectedTetrahedraMapper (0x58ae490): The required
extensions are not supported.<br>
<br>
This is complete unknown terrain for me.<br>

progress! it sounds like volume rendering is working on the
wavelet dataset.<br>
<br>
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.<br>
<br>
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. <br>
<br>
If all else fails post the dataset to the list. After creating
your cube go to the file menu and "save data".<br>

Hi Burlen, <br>
<br>
I have upgraded to the AMD drivers. Thanks for the hint. It has
improved the situation a bit.<br>
<br>
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.<br>
<br>
The situation with my own cube, though, has unchanged.
unfortunately. <br>
The cube disappears in "volume" representation node, also when
I re-inserted scalar values for each of the 8 vertices.<br>

Hi Bertwim,<br>
<br>
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.<br>
<br>
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 <a href="http://support.amd.com/en-us/download" target="_blank">AMD drivers</a>.
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.<br>

Aashish, <br>
<br>
Thanks for the suggestion.<br>
<br>
However, doing this gives me all
kinds of opengl errors (invalid
instruction).<br>
<br>
Besides that, the wavelet gives me a
cube indeed, but I need to
understand when <br>
I can have a volume rendering. I
created new Source's (e.g.
tri-prism, a wedge, <br>
a box with boundaries of finite
thickness etc.). But I cannot get
volume rendering<br>
to work, grrrrrr. (See other thread)<br>
<br>
Kind Regards,<br>
