1) Does the constructor public BoundingPolytope(Bounds[] boundsObjects) create a Polytope that is a convex hull around the pasted in Bounds objects? i.e. a "tight" Polytope around the corners of say several boxes. Or is it some other containment geometry like a box? 2) Can anyone tell me the technique for generating the Planes array that BoundingPolytope needs from a GeometryArray? i.e. given a set of triangles make a set of planes... On a side note, this is exactly the kind of functionality that should be in a Bounds Utility class. (As well as the intersect calls, the transform calls, the combine calls...why do my bounds objects have to carry around all that extra memory for those calls, especially since bounding objects get use ALOT in an application. I know, I know, in Object-Oriented we have infinite memory. - Oh No, OO is choking meeeee!!!!) 3) If I wish to use "off axis" bounding boxes I need to use BoundingPolytopes, right? If I make a box Polytope and transform it, it will be transformed just like geometry and be off axis, right? If you transform a axis-aligned BoundingBox, doesn't that cause the boxes dimension to change because of the interpretation of the upper and lower bounds points? And if so, why does BoundingBox have that call, it seems very misleading. -- __________________________________________________________ Shawn Kendall Full Sail Real World Education Course Director 3300 University BLVD Real Time 3D for Gaming Winter Park FL 32792 [EMAIL PROTECTED] http://www.fullsail.com __________________________________________________________ =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
