Detailed Description

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.

Constructor & Destructor Documentation

rPrimitive::rPrimitive	(	const GeoInfo *	info,
		const Primitive *	p
	)

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.

rPrimitive::rPrimitive

const rPrimitive &

b

Copy constructor.

rPrimitive::~rPrimitive

[virtual]

Base destructor does nothing.
