Hello Manfred,
What I meant with "like for the textures" was the filtering of the
2D-textures for a visualization on a Quad. Sorry. Thanks for your
answer. If I could work on Linux...

Hello Vincent,
That's nice but for that I need to compile an inherited class and that's
what I can't do for the moment. Is there a possibility to change the
filtering dynamically like for the textures ?
Wait, you can change the filtering mode for volume textures? I am not
aware of having implemented functionality like that. As far as I can
tell from the code, you need to overload the brickActivate method of
your shader. For the texture filtering is hardcoded in OSGBrick.cpp.
With the volume texture filtered nearest neighbor it would not matter
if the color table lookup is performed with nearest neighbor or linear
filtering since the texture lookup itself would only produce discrete
sample values.
Manfred.
