Interactive crayon rendering for animation
Halstead, Howard John IV
MetadataShow full item record
This thesis describes the design and implementation of an interactive, nonphotorealistic rendering system for three-dimensional computer animation. The system provides a two-dimensional interface for coloring successive frames of animation using a virtual crayon that emulates the appearance of hand-drawn wax crayons on textured paper. The crayon strokes automatically track and move with threedimensional objects in the animation to preserve temporal coherency of strokes from one frame to the next. The system is intended to be used as an interactive renderer in conjunction with third-party three-dimensional modeling and animation tools.
