Dissertation, Thesis, Chapters and Course Notes

Skeletal Design of Natural Forms, Ph.D. Dissertation, University of Calgary, 1995. This dissertation examines the use of inner structure to represent and articulate complex, natural forms. Contributions include analysis of convolution applied to skeletons and new methods for the addition of surface detail, control of surface bulging, and the combination of parametric and implicit surfaces.
