[vtkusers] Problem with volume rendering,

[cavallo at kip.uni-heidelberg.de]

hy,
i'm using vtk 4.0 from cvs on a linux box with different video boards but
on almost of these board show just a black window when i'm testing the
example under VolumeRendering/Tcl/SimpleRayCast.tcl.

I tried in that sequence:

nvdidia tnt2 vanta with nvidia gl drivers (black window),
matroxmga400 (it works),
matrox g550 (black)
nvidia tnt2 vanta (black).

all these machines are running xfree86 4.2.0 (suse7.3).
I'm bit frustrated and i like to display volumes: any suggestion?
thanks in advance,
antonio cavallo


ps i've set the VTK_DATA_ROOT to the right path.
