Understanding Mantra raytraced shading

Understanding Mantra raytraced shading Explains the background details of how Mantra uses raytracing to shade objects in the scene. On this page BSDFs How Mantra ray traces surfaces Ray tracing volumes Using BSDFs in shaders Tips BSDFs A bidirectional scattering distribution function (BSDF) controls how light reflects off a surface. BSDFs are probability models. Given a certain angle of incidence, a BSDF will calculate a the probability that the light ray will bounce off the surface in a certain dir
