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 00077 // 00078 // 00079 // Please email bug fixes or improvements to John W.
