We are about to switch to a new forum software. Until then we have removed the registration on this forum.
let's say I import a model of a plane. I need to rotate each axis independently like in 3D software where you have option to select to rotate model around local coordinate instead of world coordinate. How do I achieve that in processing?
They'll be other methods, but the most straightforward is to draw the object at (0, 0) or (0, 0, 0), rotate it and then translate it to where you want it.
Doing this without gridlock is difficult using Processing rotations from what I remember a while back. You would have to write functions that determine the order of rotations to do. Otherwise you could maybe find code for quaternion or matrix rotations.
ok i found a solution, using quaternion to repesent orientation. Then multiply that with new quaternion to create a new orientation.
