Light & Skin Interactions

Simulations for Computer Graphics Applications


  • Gladimir Baranoski, Associate Professor and leader of the Natural Phenomena Simulation Group, University of Waterloo
  • Aravind Krishnaswamy, Senior Computer Scientist, Visual Computing Lab at Adobe Systems Inc.

Light and Skin Interactions immerses you in one of the most fascinating application areas of computer graphics: appearance simulation. The book first illuminates the fundamental biophysical processes that affect skin appearance, and reviews seminal related works aimed at applications in life and health sciences. It then examines four exemplary modeling approaches as well as definitive algorithms that can be used to generate realistic images depicting skin appearance. An accompanying companion site also includes complete code and data sources for the BioSpec model, which is considered to be the most comprehensive first principles model in the field. Despite its wide scope of simulation approaches, the book’s content is presented in a concise manner, focusing on relevant practical aspects. What’s more, these approaches can be successfully applied to a wide range of additional materials, such as eye tissue, hair, and water.
