Detailed Description

Arbitrarily-oriented disc.

The point Center is the center of a disc in the plane with normal Normal. The disc has an OuterRadius. If InnerRadius is greater than 0, the domain is a flat washer, rather than a disc. The normal will get normalized, so it need not already be unit length.

Generate returns a point inside the disc shell. Within returns true for points within epsilon of the disc.
