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>
<br>
Regards,<br>
Bertwim<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 moz-do-not-send="true"
href="http://support.amd.com/en-us/download">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>
Bertwim
