Magri D., Cignoni P., Tarini M. Anisotropic MatCap: easy capture and reproduction of anisotropic materials. In: STAG 2016 - Italian Chapter Conference 2016 - Smart Tools and Apps in computer Graphics (Genova, Italy, 3-4 October 2016). Proceedings, article n. 10. The Eurographics Association (ed.).

We propose Anisotropic MatCap, a simple data structure based on a small volumetric texture that is able to represent, under a fixed lighting, the behavior of anisotropic materials. The data structure is designed to allow fast and practical capture of real-world anisotropic materials (like for example fabrics) and to be used in real-time renderings, requiring only negligible time and texture memory overheads. The resulting technique is suited for application scenarios where digital objects must be inspected by an end user, recreating the look of an object made of a captured anisotropic material and seen under the predetermined lighting conditions. The technique proved particularly useful for garments and cloth visualization and design.
