[vtkusers] Problems with ATI video-card and vtk

[Jose Luis Pina]

Hi:

We are developing an application with vtk 4.2 and Tcl/tk 8.3 in Pentium 
III,500.
We have Linux 2.4.20-19.9SMP RedHat 9.0 and recently installed an
ATI Raedon 9200 SE Atlantis,128Mb DDR because the old Nvidia crashed.

When we try to display a volume with Ray casting, i.e Volume Rendering,
and polygons together in the same Window  (lines, cubes,...)  the volume 
disappear.
With the same vtkRenderer or with different, the volume is not displayed.
The only way to see the volume is render it alone, if we only do Volume 
Rendering it display the volume but if we resize the window some strange 
behavior appears, slow movement, flickering...
The same scripts .tcl was working fine with Nvidia.
If someone have a similar configuration or a similar problem solved, please 
notify me.
Thanks in advance Jose Luis.
