Physically-based rendering

Real-time rendering using GGX BRDF, image-based lighting, AO, tonemapped HDR, antialiasing.

Two renderers can be used: a forward renderer where objects are directly shaded and the resulting colors stored, and deferred, where all scene information (such as albedo, normals, material ID, roughness,...) is rendered to a G-Buffer before being used to render each light and ambient probe contribution using simple geometric proxies.

Classes
class	DebugRenderer
	Provide debuggging visualization for most scene elements. More...
class	DeferredLight
	Apply a light onto the lighting buffer using a geometric proxy (cone, sphere, screenquad). By processing all lights, the final lighting is accumulated in the buffer. More...
class	DeferredProbe
	Apply a probe onto the lighting buffer by rendering a box. The probe contribution weight is accumulated in the alpha channel. More...
class	DeferredRenderer
	Performs deferred rendering of a scene. More...
class	ForwardLight
	Store lights data for forward rendering in a GPU buffer. More...
class	ForwardProbe
	Store environment probes data for forward rendering in a GPU buffer. More...
class	ForwardRenderer
	A renderer that shade each object as it is drawn in the scene directly. More...
class	PBRDemo
	PBR rendering demonstration and interactions. More...
class	PostProcessStack
	Apply post process effects to a HDR rendering of a scene. More...
