GL_TEXTURE_3D_EXT work with Linux driver ?

[kdgassiot]

I am compiling a volume visualization sample from ATI (RadeonVolVis) on my Linux box with a GeForce 3 Ti500 card, using the Nvidia Linux Driver. The code works on Windows, and I think I have everything correct for Linux, but when I display it, there is no texture visible on the slices. Does the GL_TEXTURE_3D_EXT extension work under Linux ? I am using the 1.0.3123 version of the driver and GLX libraries from Nvidia. The extension says it is supported when I query the extensions, and the codes are in gl.h ....

If anyone knows if this is supposed to work, I would appreciate it !

Thanks,
Kevin

Hi,

I don't know about the extension, but 3D-textures are supported in the OpenGL standard at least since OpenGL 1.2 (see glTexImage3D).

I played with a vol-vizualizer (about a year ago iirc) with the nvidia driver on a tnt. it was slow as hell (no hw support) but worked.

So I think it should work as an extension, too if the drivers reports that it has the extension..

maybe the texture loading failed somehow?
