Glad the 3D caught your eye :-)
converting 3D to laser is not a simple thing. Basically you need some sort of a cartoon render-er with vector output. The vector output can then be converted to laser frames.
The 3D stuff I work on has been named laserGL ;-) It is not based on openGL but it has been made so the function calls to manipulate the 3D world are *very* similar to openGL so someone with openGL coding skills could easily code with this laser library. Possibly openGL code can be converted to laserGL code without too much effort. However, the 3D mesh / object data is a bit different in nature.
This could be the rumor you heard of ;-)
do you code yourself?
