cheers all
Yeah Wodzu, i just read the section in the red book about the perspective matrix, and how you can draw 2d menus using the glOrtho. Since the perspective matrix is 2 deep, you can switch to glortho just to draw the menus etc...
Glu(OpenGL Utility Library) is like another layer on top of OpenGL. So commonly used routines would be included, to extend from OpenGL. I think thats right describing it like that.
Does anyone have a camera class that i could take a look at? I want to try to implement my own, so i can get a better understanding.
