Casey Muratori on Opening the Game Engine Black Box

Casey Muratori distinguishes systems whose implementation is inaccessible from systems we simply have not investigated. Using game engines and normal mapping, he shows how a familiar engine feature once required developers to explore an unknown frontier. His normal-map demonstration compares a detailed mesh with a much simpler one and explains both the shading benefit and the silhouette limitation. From How to Open a Black Box, his public reconstruction of a MIT GAMBIT lecture.
