Hi, i’ve recently came upon an odd problem,
I have a bunch of polygons that are textured using a 3D texture, thing is on my pc at home it works fine, but I ran it on another system today and it decided not to work :S
The data is all there, and the polygons display
however, they are all white and untextured.
Just wondered if anyone else had came accross this or anything similar? Could it just be a setup problem?(hopeful lol)
Thanks
Mal.

It could be a driver or version problem if the card/os on the system that didn’t work has bad opengl support or is older. I believe 3d textures came around in version 1.2 or 1.3. Also, it could be that the card didn’t have enough memory for the texture (although I’m not exactly sure what drivers do in this situation, maybe they’d just fall back to software).
Ihkbob is right, 3D textures were promoted to core in GL1.2 which is quite old now.
This likely means one of two things;
1.) you don’t have an OpenGL driver installed and it’s defaulting to the Microsoft 1.1 renderer
2.) you are using 3D textures that exceed your GPU’s MAX_3D_TEXTURE_SIZE
Just for reference here’s the extension specification, http://opengl.org/registry/specs/EXT/texture3D.txt
And I’ve found it useful to run the OpenGL Extensions Viewer app to tell me basically everything there is to know about my card’s supported features, extensions, and driver versions… http://www.realtech-vr.com/glview/
