[JAVA3D] Bounds (Tight) for a Non-Convex shape?

[Sam Hasinoff]

How would one go about building a BoundingPolytope for a non-convex shape? I'm working with shapes that are almost (but not quite) convex, and I want to obtain some tight bounds for them. Apparently, BoundingPolytope will not generate the convex hull for you, neither through the constructor nor the combine method.   If Java3D just isn't capable of this... does anyone know of some free (for educational use) code that is?   Thanks in advance.   -- Sam Hasinoff Computer Science University of British Columbia
