Virtual Humans Forum: Synthesizing human skin
Christophe Hery, Lead Research & Development Engineer, Industrial Light and Magic

Achieving believable rendered skin, with all its nuances, is currently more of a black art than a science. The last few years have seen advances in lighting models, in particular in regards to translucency simulation. However, many artists have a difficult time reconciling the theory with practical production methods. We will be focusing on simple recipes, showing what data needs to be acquired from a human actor and how to feed this data into a rendering pipeline. Along the way, we will take the example of the cg baby from the movie: Lemony Snicket, A Series of Unfortunate Events

Christophe Hery joined Industrial Light & Magic in 1993 as a senior technical director on The Flintstones. Prior to that, he was working for Acteurs Auteurs Associes (AAA) studio in France, setting up a CG facility devoted to feature film production.
As a research and development lead, Hery has been working on skin research as well as supporting shaders and rendering issues. In 2003, Hery was the recipient of a Technical Achievement Award for the development of practical methods for rendering skin and other translucent materials using subsurface scattering techniques. He is currently working on a project on creating talking digital clones and all associated tools and developing processes.

Since 1975, Industrial Light & Magic (ILM) has been providing post-production visual effects services to the entertainment industry. Motion pictures, commercials, trailers, music videos and special venue projects have utilized ILM's unequaled artistry in techniques such as model making, matte painting, computer-generated imagery, digital animation and a variety of related processes required in the production of visual effects. Groundbreaking software required for digital image production has been developed and shared with the industry at large and adopted by other companies and software manufacturers. ILM regularly consults with some of the industry's most highly regarded filmmakers on proof of concept tests. ILM has been associated with fourteen movies which have earned the Oscar for Best Visual Effects and has been awarded seventeen technical achievement awards from the Academy of Motion Picture Arts and Sciences.
