Pre-multiply a rotation matrix by a matrix which maps the z-axis to the negative x-axis, the y-axis to the z-axis and the x-axis to the negative y-axis. ANIM_V_PERMUTE This has the effect of twisting an object in the default view orientation into the default object orientation before applying the matrix. Given a matrix designed to operate on an object, yield a matrix which operates on the view. |
