Detailed Description

Sphere.

The point Center is the center of the sphere. OuterRadius is the outer radius of the spherical shell and InnerRadius is the inner radius.

Generate returns a random point in the thick shell at a distance between OuterRadius and InnerRadius from point Center. If InnerRadius is 0, then it is the whole sphere. Within returns true if the point lies within the thick shell at a distance between InnerRadius to OuterRadius from point Center.
