Special Effects   Chair: Ken Musgrave , MetaCreations   3D Rendering Effects for 2D Animation   3D shading and rendering techniques can be applied to animated drawings, after automatically constructing surfaces from the drawings. Modeled surfaces can also track drawings to produce shaded and textured animation.   Lance Williams DreamWorks SKG 1000 Flower Street Glendale, California 91201 USA lwilliams@dreamworks.com   Image-Based Techniques for Object Removal   A simple image-based rendering technique for producing a clean plate from the original background. The algorithm consists of four steps: object identification, image depth extraction, image projection, and incremental rendering. Simply put, the algorithm makes a hole where the bad pixels are, then uses neighboring frames to incrementally fill the hole with good pixels.   Rod G.
