I have a point A:
Known it's Cartesian coordinates (X,Y) and its Euler angle Aka head rotation (R,P) respectively Roll (rotation around X axis) , Pitch (rotaion around Y axis). (I'm not using Yaw because i'm working in graphics 2D)
Now I have a point B:-
Knows its Euler Angles only (X',Y') .
What I need to find is the coordinates of the point B.
