the warning is just a warning the algorithm continues to work as it
had in the past. (right?) Maybe the warning could be removed in
release builds.<br>

I replied into the bug itself, but the simple answer is that
I didn’t build this version of Mesa – it was provided by a
vender and I have no control over it. And it has to work on
this version of Mesa, as it has before.<o:p></o:p></span></p>

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"

I' starting to wonder if I have two issues occurring

In a new thread I just posted I described my problem

I need to write to a vtk file first and load it

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>

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>
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"
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

<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

I cannot get volume

to work, grrrrrr.

get an a box
