Detailed Description

Rhombus-shaped planar region.

p0 is a point on the plane. u0 and v0 are (non-parallel) basis vectors in the plane. They don't need to be normal or orthogonal.

Generate returns a random point in the diamond-shaped patch whose corners are o, o+u, o+u+v, and o+v. Within returns true for points within epsilon of the patch.
