On this second of three titles in the Matte Surface rendering series, Scott shares with you the round geoform shading techniques he has been teaching for over a decade. He explains and demonstrates the basics of how our brains interpret round forms via value changes. Scott uses observational video clips of a cylinder, cone and sphere in various lighting scenarios to reinforce his value assignment strategy. Walking you through several sketches, he shows his techniques for properly constructing the cast shadows of each of the round geoforms. At the end of the title, Scott renders a more complex form (shown on the cover) from start to finish, demonstrating the use of pencil, chalk and marker. This lecture is intended as a "must-watch" for beginners and a good refresher for the more experienced artist/designer.
