Path tracer

A basic diffuse path tracing demo, with an interactive viewer to place the camera.

Classes
class	BVHRenderer
	Renderer coupled with a basic diffuse path tracer. The user can move the camera anywhere and trigger a path-traced rendering. Can also display the raycaster acceleration structure. More...
class	PathTracerConfig
	Path tracer demo configuration. Parameters for offline rendering. More...
class	MaterialGGX
	CPU methods for evaluating the Cook-Torrance BRDF (Lambert+GGX/Towbridge-Reitz) for a given set of parameters, and sample a ray following the distribution of normals. More...
class	MaterialSky
	CPU methods for evaluating the atmospheric scattering model used by the sky background. More...
class	PathTracer
	Unidirectional path tracer. Generates renderings of a scene by emitting rays from the user viewpoint and letting them bounce in the scene, forming paths. Lighting and materials contributions are accumulated along each path to compute the color of the associated sample. More...
class	PathTracerApp
	Viewer coupled with a basic diffuse path tracer. The user can move the camera anywhere and trigger a path-traced rendering. Can also display the raycaster acceleration structure. More...
