just the pure math side of space transformation:
if I am right, the 3x3 matric manage rotation +scaling (in 3d : sin/cos of
the angle are involved); the last row managing the translation;
actually, the great thing with j3d (or any 3D API) is that you do not need
(well, at least at the beginning) to
know much about this as methods can be used directly to rotate/scale/etc..
I remember once accessing a great web site for spacial matrix computation
but can not find it back.
Anyone here who could point us to such a site?
Good luck
