I’ve tried to use glDrawRangeElements function but my compiler didn’t recon it. Is it possible to be caused by the fact I’m using OpenGL v. 1.1 ?
Which of those fuctions is faster: glDrawRangeElements or glDrawArrays ?

Yes, it is possible that glDrawRangeElements won’t work because you’re compiling with OpenGL 1.1.

In fact I’d say it’s down right probably the problem!

(I know because it happened to me yesterday )

Maybe you need the header file “glext.h”.
