In Silico introduces Maya programming into one of the most fascinating application areas of 3D graphics: biological visualization. In five building-block tutorials, this book prepares animators to work with visualization problems in cell biology. The book assumes no deep knowledge of cell biology or 3D graphics programming. An accompanying DVD-ROM includes code derived from the tutorials, the working Maya computer files, and sample animated movies.
*Teaches artists and scientists to create realistic digital images of humans and nature with the popular CG program, Maya
*This self-contained study guide includes background, foundations, and practice
*Step-by-step example programs and end-result demonstrations help readers develop their own portfolios
*Gorgeous four-color screen shots throughout
