This class can be used if an IGeometricObject with a ray shape is needed. Use the Ray structure instead if you need a lightweight representation of a ray (avoids allocating memory on the heap).

In contrast to a real ray, a RayShape object has a finite length! Infinite rays should not be used because finite rays are faster and produce less numerical problems.

Important: Do not put rays into composite shapes (for example CompositeShape). If a composite shape collides with another object, all contacts of this object pair are merged into a single ContactSet. Thus, ray hits of child rays of the composite shape are "merged" with normal contacts of other child shapes; the result is undefined.
