Trajectory prediction in Unity

Predict trajectory with Physics.Simulate. Not sure about performance if there is a lot of stuff going on, but should be absolutely fine for small simulations. Anyway in case you use Physics.Simulate a lot dont forget to always profile before optimizing. Or if you are still in a preproduction phase, make a small proof of concept with expected amount (and more for greater confidence) of operations to simulate, so you can be sure that this approach is suitable for your case.

Polygon Clipping (Part 1 & 2)

Polygon clipping is an interesting problem: how do you intersect, union, or diff two polygons?
The Greiner-Hormann clipping algorithm is quite beautiful and intuitive. However the Greiner-Hormann clipping algorithm cannot deal with coincident lines. This turns out to be a huge pain – so there is part 2 that works for all polygons.
