Lighting Namespace Reference

Detailed Description

The lighting subsystem allows for attaching light source functionality to a GraphicsEntityId.

It currently supports a deferred renderer, dynamic global and local shadows, as well as light probes which are used for dynamic or static environment reflections and irradiance.

Classes
class	CSMUtil
	Helper class for creating and rendering Cascading Shadow Maps. More...
class	LightContext

Functions
void	ComputeFrustumPoints (float cascadeBegin, float cascadeEnd, const float aspect, const float fov, Math::vec4 *frustumCorners)
	Compute frustum points using computed frustum and cascade intervals, basically stolen from Math::frustum.
void	ComputeAABB (vec4 *lightAABBPoints, const vec4 &sceneCenter, const vec4 &sceneExtents)
	__ImplementContext (LightContext, LightContext::genericLightAllocator)
