6 Physically Based Rendering Using the glTF 2.0 Shading Model
Join our book community on Discord
This chapter will cover the integration of physically based rendering (PBR) into your graphics applications. We use the glTF 2.0 shading model as an example. PBR is not a single specific technique but rather a set of concepts, like using measured surface values and realistic shading models, to accurately represent real-world materials. Adding PBR to your graphics application or retrofitting an existing rendering engine with PBR might be challenging, as it requires multiple big tasks that work simultaneously before a ...
