This is a pretty simple question. If I was to use multiple images in a single texture for a 3D cube, how would I go about re-using each vertex (having 8 total vs 24)?
With a single buffer of 8 vertices, I don't see how I'd properly reuse the UV values.
Any help on that? I know it's not terribly clear, but I figured it was a simple question.
The 2D method is pretty easy, the next coordinates would be the same as the first (0,0 and 0,1 respectively).
However, the above 3D version has me quite befuddled.
