I have a few extra methods like that in PraxisLIVE (such as 7 parameter image()) but haven’t quite got around to this one yet. Interestingly, there is a 4 parameter version of rotate() in Processing already though - /\*\* \* Rotate around an arbitrary vector, similar to glRotate(), except that it \* takes radians (instead of degrees). \*/ publ…
