As a professor for almost thirty years, Gregory S. Johnson has had the privilege of teaching thousands of students a wide array of courses including digital sculpture, 3D modeling, texturing, animation, rigging, visual effects, digital painting, programming, game design and development. This book is a compilation of material developed from his introduction to digital sculpting lectures and all of the excellent advice cultivated over the years. Gregory is a member of the International Game Developers Association (igda.org), the Guild of Natural Science Illustrators (www.gnsi.org), and the Association of Science Fiction Illustrators (asfa-art.ning.com) and has worked for years as a 3D artist.
