"im using opengl"


hi guys, im very noob on 3d, but i have good know how with opengl 2d (this helped), i already achieved how to draw the cubes and basic control of camera.

but in some cubes i have to colorize 1 side (or 2 or 3) with a dif color,
like http://upload.wikimedia.org/wikipedi...onal_prism.png

and i'm also wondering if i can make the cube bords with another dif color to make it more visible :?

thanks,
Arthur.
