Observe the non-commutative order M*rot [2D & 3D]
I don't like the rotation of the sphere ... welcome to doctor it !
Don't miss Paul W. rotate RGB image [far superior to Mathcad IMPROC !].
This compendium includes the 3 most used rotation system:

1. Euler [Roll, Pitch, Yaw]
2. Parametric [x,y,z,"t"]
3. Quaternion

Hello Ber7 !

I can see what you are trying to do ... let me find "Wind Mill" equations,
if they exist ?

Cheers, Jean
