00061 // compute the 'best fit' oriented bounding box of an input point cloud by doing an exhaustive search.
00062 // it spins the point cloud around searching for the minimal volume.  It keeps narrowing down until
00063 // it fails to find a better fit.  The only dependency is on 'double_math'
00064 //
00065 // The inputs are:
00066 //
00067 //         vcount    : number of input vertices in the point cloud.
00068 //         points    : a pointer to the first vertex.
00069 //         pstride   : The stride between each point measured in bytes.
00070 //
00071 // The outputs are:
00072 //
00073 //         sides     : The length of the sides of the OBB as X, Y, Z distance.
00074 //         matrix    : A pointer to a 4x4 matrix.  This will contain the 3x3 rotation and the translation component.
00075 //         pos       : The center of the OBB
00076 //         quat      : The orientation of the OBB expressed as quaternion in the form of X,Y,Z,W
