point back to origin p.x cx p.y cy rotate point float xnew p.x c p.y s float ynew p.x s p.y c translate point back p.x.. c p.y s float ynew p.x s p.y c translate point back p.x xnew cx p.y ynew cy If the rotation is exactly the wrong side around.. I've messed up the rotation. In this case it is float xnew p.x c p.y s float ynew p.x s p.y c I hope one day I'll remember..
