Anisotropic Map
A texture that controls the shape of the specular highlights from real-time lights, often used for hair shading.
The texture is very similar in concept to a normal map, except instead of controlling surface normals, it stretches the specular highlight in specific directions across the surface.
Anisotropic Tutorials
- http://stephenjameson.com/tutorials/anisotropic-shader-for-hair/Anisotropic Shader For Hair by Stephen Jameson provides a breakdown of a shader setup in the Unreal Development Kit (UDK).
- HAIR!? thread on Polycount by Paul 'Prolow' Lohman has some examples of an anisotropic hair shader in Maya.
