Hi

At the opengl.org main page you can see a topic ‘Cubic Environment mapping demo using OpenGL’
…
use of a number of OpenGL extensions
…
GL_ARB_texgen_reflection

GL_ARB_texgen_reflection
is that extention extist ? I couldn’t find specification for it
at http://oss.sgi.com/projects/ogl-sample/registry/
Is it renamed NV_texgen_reflection?

Thanks
Michail

I’m only aware of GL_NV_texgen_reflection…

This extension does not exist (nor does EXT_texgen_reflection). ARB_texture_cube_map does include the texgens, though.

Radeon has both a EXT_texgen_reflection and a NV_texgen_reflection. Don’t know if they are the same …

As I mentioned in another thread, EXT_texgen_reflection was “promoted” to EXT without our advice or consent. It’s the same as NV_texgen_reflection, and so promoting it served no purpose.

Use NV_texgen_reflection, EXT_texture_cube_map, or ARB_texture_cube_map, but don’t use EXT_texgen_reflection, which we do not (and will not) support.
