Shedding real light on some not so real things. Image based lit Stanford dragon: diffuse SH specular environment map sampling. Many real-time engine writers have concentrated on getting their equations right. The most recent result is the. Siggraph Physically Based Shading Course. I will roughly lay out the basic principles of PBS and refer to other very good online blogs which have covered most of the details that do not need to be repeated ad absurdum.

Shedding real light on some not so real things. Notes on importance sampling. Some tutorials on importance sampling specular terms that are out in the wild have what I found to be an information gap: the step from the PDF to the actual sampling function is missing. Hopefully this step-by-step guide can help out one or two other confused readers. I checked all integrals with Maxima. Simplify - Simplifiy Expression. Or put it into Wolfram Alpha and check the.
