Detailed Description

This is the base class of anything renderable! We use this class to handle renderable objects that can have simple geometry such as triangles, spheres, etc.

Rendering primitive parent class. These objects are usually created by a 'Primitive' subclass when rendering is done. The primary difference between two classes is that the 'Primitive' always remains in scene space, or world space, and a rPrimitive is allocated per render sample and transformed into clip and screen space. These objects are destroyed after rendering is complete.
