Vector Transformations

Two important transformations for vectors are already implementated in POV-Ray as basic functions by macros.

vrotate( V, <Rotate_X, Rotate_Y, Rotate_Z>)
Rotation of a vector V around the center <0,0,0>
by a rotation vector <Rotate_X, Rotate_Y, Rotate_Z>.

vrotate(< 2.5,1,0>, < 0, 90, 0>)

vaxis_rotate( V1, V2, A)
Rotates V1 around V2 by A degrees
Rotation of a vector around another vector as axis of rotation.

vaxis_rotate(< 0, 1, 0.5>, < 2, 3, 0>, 70 )
