Detailed Description

Cone.

e0 is the apex of the cone and e1 is the endpoint of the axis at the cone's base. OuterRadius is the radius of the base of the cone. InnerRadius is the radius of the base of a cone to subtract from the first cone to create a conical shell. This is similar to the cylindrical shell, which can be thought of as a large cylinder with a smaller cylinder subtracted from the middle. Both cones share the same apex and axis, which implies that the thickness of the conical shell tapers to 0 at the apex. InnerRadius = 0 for a solid cone with no empty space in the middle.

Generate returns a random point in the conical shell. Within returns true if the point is within the conical shell.
