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">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>

This is what I do:<br>
1. start paraview<br>

A cube is displayed (Outline representation).<br>
3. Select 'Volume" representation"<br>
<br>
cube disappears. Then: <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
