What is Anisotropy?

Anisotropy is a term used in 3D visualization to describe the variation of a material’s physical properties in different directions. In other words, anisotropy refers to the directional dependence of a material’s properties. This can be visualized using various methods, including isosurfaces and volume rendering.

For example, if you have a cube made of plastic, its physical properties (e.g. density, color) will be different depending on which direction you measure them. If you measure the density along one of the cube’s faces, it will be different from the density measured perpendicular to that face.This directional dependence can be exploited to create more realistic 3D models.
