Thread: Does my card support multitexture our not?!?!

Hello again,

I'm trying to implement a 2 pass multitexture algorithm on a NVidia GeForce FX 5200 w/64 mb VRAM with my iMac G5. In the article I was reading, it said to check for GL_ARB_multitexture as well as GL_EXT_texture_env_combine. My card supports GL_ARB_multitexture, but not GL_EXT_texture_env_combine. Is my card bad, and do I really need support for this extension? Here's the list of extensions my card does support:

GL_ARB_vertex_program
GL_ARB_vertex_blend
GL_ARB_window_pos
GL_ARB_shader_objects
GL_ARB_vertex_shader
GL_EXT_multi_draw_arrays

Thanks

I'm sure a 5200 supports it since my GeForce 3 TI does.

I'm just trying to do a bump mapped cube, but the only multitexturing commands it uses is basic commands to set up 2 multi textures, and then it draws them with glMultiTexCoord2fARB. Maybe I'll just try it without GL_EXT_texture_env_combine.

a list of all cards that support that extension:
http://www.delphi3d.net/hardware/ext...re_env_combine

that does list several versions of the 5200, not sure why yours says it doesn't.

If you want to know exactly what he does, look here: http://msi.unilim.fr/~porquet/glexts...mbine.txt.html

Oops, I think I had a bug in my program when it retrieved the list of supported extensions . Now that the bug is fixed, it now shows way more extensions than the previous list, and it supports GL_EXT_texture_env_combine.
