Bump mapping with ext_texture_env_dot3

I’m using this extension to to per pixel bump mapping and it’s working ok, except that I can’t find out how to specify the light vector.

I know how to calculate it but can’t finf the opengl call needed to actually set it :slight_smile:

I’d appreciate any information or pointers to a web page you might have.


This is not the forum for this type of questions, this is for beginner stuff.


Ok, it was a simple question on how to call the API. That seemed like a beginners question to me :slight_smile:

But point taken… I’ll ask elsewhere, although I think I’ve found my answer already.
