Many global illumination algorithms generate directionally-and positionally-varying radiance data that then need to be somehow re-sampled and used for nal shading. This operation should lter all light over the incident hemisphere through the BRDF to generate an accurate image. This can be done analytically for simple BRDFs, such as Lambertian or Phong-like… (More)
