file	EnvironmentMap.cpp [code]
	Environment map using latitude-longitude format. An environment map roughly models distant illumination surrounding a scene by conceptually surrounding the scene with a spherical emitter that emits light inwards according to a distribution defined by a 2D 'environment' texture map that is projected onto the surface of the sphere. Note the term HDR environment map is thrown around a lot; the only difference is that the underlying environment texture is stored in some type of high dynamic range format, such as OpenEXR or HDR.
file	EnvironmentMap.h [code]
file	NullEmitter.cpp [code]
	Null emitter which doesn't emit any light, defined at a single point in 3-space.
file	NullEmitter.h [code]
file	OmniEmitter.cpp [code]
	Point emitter / light which emits light uniformly in every direction, defined at a single point in 3-space (omnidirectional).
file	OmniEmitter.h [code]
file	OrientedEmitter.cpp [code]
file	OrientedEmitter.h [code]
	Area emitter/light which emits light uniformly across a 2D domain, defined at a single point in 3-space, and restricted to the local positive hemisphere (oriented along hemisphere about local surface normal).
