get pitch, yaw, roll from a CMRotationMatrix

Question

I have a CMRotationMatrix *rot and i would like to get the pitch, yaw, roll from the matrix. Any ideas how i could do that?

Thanks

Answer 1

pitch, yaw, roll from the matrix. Any ideas how i could do that?

In which order? Pitch, yaw and roll, commonly called Euler angles, don't represent rotations unambigously. Depending on the order you carry out the individual sub-rotations you end up with completely different rotation matrices.

My personal recommendation: Don't use Euler angles at all, they just call for (numerical) trouble. Use a matrix (you already do) or a quaternion.
