Creating Accurate Anisotropic Lights with Linear Transformed Cosines
Linearly Transformed Cosines, or LTCs, are a set of tools used for quick and accurate shading in games. They're great because they can be calculated quickly. Right now, game engines use LTCs to mimic a model called GGX, but only in its simplest form called isotropic GGX. When it comes to the more co
