Given a point P(x1,y1,z1) in 3D space and its orientation what would be
the co-ordinates of other end of the line of length L, if it starts at
P(x1,y1,z1). The rotation of point P(x1,y1,z1) takes place about its

the same question.
You’ll need to construct a rotation matrix for the orientation and then
do something like:
P2 = P1 + mat * (0, 0, L)
