I'm curious if anyone has some advice about how to perform a boolean subtract using two 3D objects in Processing. Let's say I wanted to be able to make molds (for glass, for example) out of arbitrary 3D models - I imagine taking that 3D object and 'subtracting' it from the center of a solid box, leaving the negative of that 3D object embedded in the box. Eventually I'd like to print this mold on a 3D printer, but I can handle that myself.
