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>

indeed. But I don't understand what you are saying

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>

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
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

get volume rendering<br>
to work, grrrrrr. (See

the following.<br>
<br>
When I create
a new source
(say: a box) I
get an a box
that<br>
can be
displayed via
its surfaces,
its
constituing
points, or
wireframe<br>
representation.<br>
But I need a
volume
rendering (so
that I can add
e.g. a
clipping
plane)<br>
How do I get
that?<br>
