Lately I’ve been posting large code snippets… so today I’m highlighting part of a larger snippet – The above code is the heart of a small experiment I created this morning. It sets up a cube for use with drawTraingles().

The rest of the code can be read here:

Have a look at the swf here…

I also put it on wonderfl…
