Flow Map
A flow map stores directional information in a texture, also called a vector field. This can be used to control the UV coordinates for a water texture, to make the texture flow around rocks. It can also be used to control the direction of a hairstyle's anisotropic specular highlight. Similar map types include CurvatureMap, DuDvMap, NormalMap, RadiosityNormalMap, VectorDisplacementMap.
