| | | | | 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. | |
