I can get nice stuff on screen with glVertex3f calls, but what should I do, if I have an array and I have allocated lots of memory for it, and I would then like to use this array as an input-array for gl-functions? Kind of redirecting the input. Or in other words, I have memory for an image, and I want to draw stuff into it with gl-functions. Any ways to do this?

Uhm, google up glDrawElements, glDrawArrays, and glArrayElement.

Also, glColorPointer, glVertexPointer, and glTexCoordPointer.
