I saw the 3d functions for actionscript and I was wondering if someone took the liberty and tred to understand them. I need to use them badly for a project and if someone has some coments on them i would be glad to read them!
Hum, I was once experimenting with flash and 3d, this may not be exactly what you are looking for but its well commented I think. Its basically a real and not an abstract or simplified 3d engine basis. Unfortunatelly it runs kinda slow and it crashes due to a bug (which was fixed but I accidentally redid it and don't remember what it was).
If you are looking for the typical 3d stuff you may want to look in the sources section of flashkit, there are more then enough examples of the normal wireframe cubes and similar engines.
