Sets the elements of the 4x4 matrix m so it becomes a 3D rotation matrix.
m
The resulting matrix will rotate points in the yz-plane around the x-axis when multiplied by a column vector (see mulV).
mulV
The direction of rotation will be counterclockwise for positive values of r when the axis points towards the observer
r
a 4x4 matrix object
the rotation as an angle in radians
m set to be a 3D rotation matrix
