| | | | | Linear space lighting is a term that game developers are becoming ever more used to hearing as games reach for the next level of realism with physically based rendering models (PBR). Though linear space and its counterpart, gamma space, are fairly simple and important concepts to understand, many developers don't learn what these terms really mean. This document will define gamma and linear space, how they differ, and how it applies to the Unity engine. | |

| | | | | Linear-space lighting is the single most important thing for graphics programmers and technical artists to know. It's not that hard, but for whatever reason, no one really teaches it. Personally, I got a BS and MS at Georgia Tech, took basically every graphics class they had, and didn't hear about it until I learned about it from George Borshukov. This post is essentially the short version from my talk at GDC this year. You can check out the slides for more details. | |

| | | A long, long time ago, in pretty much the same place I'm sitting in right now, I was learning how one would do 2D lighting with soft shadows and discovered the age old adage in 2D graphics: linear gradient lighting looks better than mathematically correct inverse square lighting. Strange. I brushed it off as artistic license and perceptual trickery, but over the years, as I dug into advanced lighting concepts, nothing could explain this. It was a mystery. Around the time I discovered microfacet theory I figured it could theoretically be an attempt to approximate non-lambertanian reflectance models, but even that wouldn't turn an exponential curve into a linear one. | ||
