Triangle Strips
Author
To my inexperienced, just-jumping-into-3D-ness...
Triangle Strips appeared to be drawing triangles from the last 2 plus the one you next define so it would be:
1 3 | 5 7 |
| |
2 4 | 6 8 |
etc. (for sides of a cube)
Something tells me I''m incredibly wrong, because then I wouldn''t be able to create an entire cube, just the sides around it, not the top/bottom.
Help?

You are wrong, but you still can''t do a cube with a triangle strip without hiding some vertexes.
Assume 6 vertexes a,b,c,d,e,f
Then the triangles rendered, in order, are:
(a,b,c)
(b,d,c)
(c,d,e)
(d,f,e)
a---c---e
| /| /|
| / | / |
|/ |/ |
b---d---f
Each triangle is rendered using one additional vertex (not two) with the two previous.
