| *[in]* **m2** affine matrix 2
| *[out]* **dest** result matrix
.. c:function:: void glm_mul_rot(mat4 m1, mat4 m2, mat4 dest)
| this is similar to glm_mat4_mul but specialized to rotation matrix
Right Matrix format should be (left is free):
.. code-block:: text
R R R 0
R R R 0
R R R 0
0 0 0 1
this reduces some multiplications. It should be faster than mat4_mul.
if you are not sure about matrix format then DON'T use this! use mat4_mul
Parameters:
| *[in]* **m1** affine matrix 1
| *[in]* **m2** affine matrix 2
| *[out]* **dest** result matrix
.. c:function:: void glm_inv_tr(mat4 mat)
| inverse orthonormal rotation + translation matrix (ridig-body)
