  ## Documentation
  -- [Filament](https://google.github.io/filament/Filament.md.html), an in-depth explanation of real-time physically
  - based rendering, the graphics capabilities and implementation of Filament. This document explains the math and
  - reasoning behind most of our decisions. This document is a good introduction to PBR for graphics programmers.
  -- [Materials](https://google.github.io/filament//Materials.md.html), the full reference documentation for our material system.
  - This document explains our different material models, how to use the material compiler `matc` and
  - how to write custom materials.
  -- [Material Properties](https://google.github.io/filament/Material%20Properties.pdf), a reference sheet for the standard
  - material model.
