Hi, I've been searching for a way to rotate a vector as vec_rotate does it. Now I'm too curious to see the algorithm behind it. Can you explain it briefly?

I guess it's three consecutive "2d" rotations (pan rotates xy, tilt xz, and roll yz). I'm not sure in which order they are performed, though.

Yes, that's the algorithm. The angle is converted to a rotation matrix, with which the vector is then multiplied.
