Local tonemapping (I'll refer to it as LTM) - a component I considered a missing piece in video games rendering, especially with physically-based pipelines and using... | |

| | | | | Implementing a Physically Based Camera: Understanding Exposure Manual Exposure Automatic Exposure Automatic exposure is the process of adjusting camera settings in response to a given scene to achieve a well exposed image.This is sometimes referred to as eye-adaptation in games. However, the goal here is to obtain settings that will be used by other rendering... | |

| | | 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. | ||
