Hi Alan,<br>
<br>
That is a different issue. You're seeing that warning because your Mesa build is missing floating point support. Some of the older releases didn't have it, however newer releases do. It's always been a build option that's off by default because of patent issues,
so you need to expeictly enable it when compiling mesa. The intention behind that (in hindsight annoying) warning is to alert you are using an ancient version of mesa and or that you may have not built mesa with floating point support. At the time the warning
seemed reasonable to me since without floating point support the projected tets algorithm *could produce precision related artifacts depending on data and rendering parameters and downloading and installing a newer mesa (or simply recompiling your existing
mesa build with floating point support enabled) is a relatively easy fix. For me I'd rather know that there's potentially a problem and update mesa, rather than scratch my head about why there are artifacts in my rendering.<br>
<br>
With regard to the current thread and Bertwim's issue with ATI GPU, I think the code is currently doing the right thing because projected tets algorithm hangs on the ATI card.<br>
<br>
A workaround if you have an ATI card is to set the "select mapper" to "Bunyk ray cast"
<br>

You could try it without modifying any code by setting the following cmake variable.<br>
<br>
VTK_IGNORE_GLDRIVER_BUGS:BOOL=ON<br>

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

I need to write to a vtk file first and load it back. I just found that when I just did that<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>
<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>

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>

When I create a new source (say: a box) I get an a box that<br>
