Chapter 6: Physically Based Rendering Using the glTF2 Shading Model

This chapter will cover the integration of Physically Based Rendering (PBR) into your graphics pipeline. We use the Graphics Language Transmission Format 2.0 (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 because it requires multiple big steps to be completed and work simultaneously before a correct image can be rendered.

Our goal here is to show how to implement all these steps from scratch. ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
