I thought it would clash with an existing P3D `rotate()` method but it seems not. Always thought it should be more like `rotateAt()` or `rotateAround()`. 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 -

```auto
/**
   * Rotate around an arbitrary vector, similar to glRotate(), except that it
   * takes radians (instead of degrees).
   */

public void rotate(float angle, float v0, float v1, float v2)

```
