This part of the book covers Physically Based Shading from the fundamental concepts to how to implement custom lighting models.
You will learn the microfacet theory, get to know many different custom lighting functions, including handy ways to visualize and analyze them and how to implement them in Unity.
Youâll learn how to hack your custom lighting functions into the Unity standard shader, so you can take advantage of its extensive functionality, including specular reflections and global illumination.
Youâll also learn how to implement advanced techniques not included in the usual type of custom lighting function, such as translucency. This part includes an overview on how to implement reflections, or how Unityâs ...
