Hi! I want to know if my OpenGL is later than version 1.1 or not. What command shall I use to obtain it?
The reason I raise this question is:
when I study using OpenGL library under Delphi 5.0 following the instruction of a reference book base on OperGL later than version 1.1, I found that OpenGL in Delphi doesn't include some routines and state variables introduced by book. For example: glEnableClientState(routine) and GL_COLOR_ARRAY(state variable).
By the way, my reference book is base on C language. However, because OpenGL is independent of operationing system, I think its identifiers should be the same no matter what language we use.
In case my version of OpenGL is too old, is it possible to update it? Because OpenGL follows the GPL license and it may be provided on Internet.
Thank you much!
