The tree model is a matrix that is applied to a cone shape. Does nutcracker actually do anything in 3D space, or... is everything done on a 2D surface?
I'm interested in two shapes -- a sphere, and a starburst. A "starburst" was created by combustionmark, it has many rays going off in in three dimensions. A starburst could be treated as concentric spheres. It also might be treated as bunch of intersecting lines, or a bunch of arches.
The existing custom model editor works in 2 dimensions. How would it handle 3 dimensions? Does it even matter if nutcracker is only working in 2D?
