Looking forward to the subsurface model introduction

[xu-xionglong]

The document of filament is the best pbr tutorial that I have ever read. However, the section about subsurface rendering is still in the progress. Is there a plan for finishing the document?

It is planned yes, I just need to find the time. Note that the subsurface is a crude approximation. You can find the source here: https://github.com/google/filament/blob/master/shaders/src/shading_model_subsurface.fs

It is heavily based on https://colinbarrebrisebois.com/2011/03/07/gdc-2011-approximating-translucency-for-a-fast-cheap-and-convincing-subsurface-scattering-look/
