could someone please tell me where I can learn about pixel and vertex shaders
there You can learn something about it
First of all, vertex and pixel shaders do not exist in OpenGL under that name. They’re called vertex and fragment programs.
Secondly, a thread has been started in the advanced forum, and you’d better check it since vertex and fragment programs are considered an advanced topic in OpenGL.
there is an extension called:
This ext. is in OpenGL 2.0 the newest version of this API
I see no one is pointing to the openGL extensions specs…
The pdf is quite large (over 1000 pages) but works well.
