## Physically based rendering ## Physically based rendering
Physical based rendering as a lighting technique that achieves a more realistic and dynamic look by applying approximations of bidirectional reflectance distribution functions that rely on measured real-world material parameters and environment lighting. *Physical based rendering as a lighting technique that achieves a more realistic and dynamic look by applying approximations of bidirectional reflectance distribution functions that rely on measured real-world material parameters and environment lighting.*

Basic implementation of a metallic-roughness based physical based rendering model using measured material parameters. Implements a specular BRDF based on material parameters for metallic reflectance, surface roughness and color and displays a grid of objects with varying metallic and roughness parameters light by mutliple fixed light sources. Basic implementation of a metallic-roughness based physical based rendering model using measured material parameters. Implements a specular BRDF based on material parameters for metallic reflectance, surface roughness and color and displays a grid of objects with varying metallic and roughness parameters light by multiple fixed light sources.

Adds ```image based lighting``` to the PBR equation. IBL uses the surrounding environment as a single light source. This adds an even more realistic look the models as the light contribution used by the materials is now controled by the environment. The sample uses a fixed HDR environment cubemap as for lighting and reflectance. The new textures and cubemaps required for the enhanced lighting (BRDF 2D-LUT, irradiance cube and a filtered cube based on roughness) are generated at run-time based on that cubemap.
