Detailed Description

A Triangle.

p0, p1, and p2 are the vertices of the triangle. The triangle can be used to define an arbitrary geometrical model for particles to bounce off, or generate particles on its surface (and explode them), etc.

Generate returns a random point in the triangle. Within returns true for points within epsilon of the triangle. Currently it is not possible to sink particles that enter/exit a polygonal model. Suggestions?
