Anyone know a quick solution to finding a matrix M in the following situation:
Let''s say we have a rotation matrix for the angles R(ax + bx, ay + by, az + bz). In this case the rotation order is XYZ.
I want to find the angles mx, my and mz that will build a matrix M such that:
R(ax + bx, ay + by, az + bz) == M * R(ax, ay, az)
That is the application of the rotation matrix for ax/ay/az on the rotation matrix for the angles mx/my/mz will produce the matrix that I already have for the angles ax+bx/ay+by/az+bz.
I know I can solve this by building inverse matrices and getting the matrix M and then decomposing to get mx/my/mz... However I''m curious as to whether there''s a quicker way to get those angles.
Thanks to anyone with any ideas...
