INFORMATION TO USERS This manuscript has been reproduced from the microfilm master. UMI films the text directly from the original or copy submitted. Thus, some thesis and dissertation copies are in typewriter face, while others may be from any type of computer printer. The quality of this reproduction is dependent upon the quality of the copy submitted. Broken or indistinct print, colored or poor quality illustrations and photographs, print bleedthrough, substandard margins, and improper alignment can adversely afreet reproduction. In the unlikely event that the author did not send UMI a complete manuscript and there are missing pages, these will be noted. Also, if unauthorized copyright material had to be removed, a note will indicate the deletion. Oversize materials (e.g., maps, drawings, charts) are reproduced by sectioning the original, beginning at the upper left-hand comer and continuing from left to right in equal sections with small overlaps. Each original is also photographed in one exposure and is included in reduced form at the back of the book. Photographs included in the original manuscript have been reproduced xerographically in this copy. Higher quality 6” x 9” black and white photographic prints are available for any photographs or illustrations appearing in this copy for an additional charge. Contact UMI directly to order.

I would also like to thank the other members of my dissertation committee, Wayne Carlson and Kikuo Fujimura, for their encouragement and support. Wayne’s advice throughout my stay at OSU and during my association with ACCAD is greatly appreciated. I vTish to express sincere appreciation to the Chamber of Mines of South Africa for awarding me the Nico Diedericks Research Scholarship in support of the flrst year of my studies at OSU. Financial support by the now defunct Centre for Advanced Computing and Decision Support, and later by the Division of Microelectronics and Communications Technology of the Council for Scientiflc emd Industrial Research is also appreciated. I would like to thank my friends and colleagues at ACCAD and CIS for inspiring me through their own work, and for helping to create a rich and rewarding environment to do computer graphics and animation research. At the risk of leaving someone out, let me mention by name Barb, Beth, Bob, Bren, Cemil, Chuck, Chitra, Dave, Don, Bd, Erika, Fhp, Kevin, Kevin, Kevin, Kikuo, Jim, John, Lawson, Matt, Midori, Meg, Moon, Nathan, Nathania, Neal, Pete, Pete, Phil, Rick, Rina, Roni, Saty, Scott, Scott, Sara, Steve, Steve, Terry, Tonya, Torsten, Traci, Viki, and Wayne. And thanks, Steve, for enduring my frequent visits to your office—I will miss them dearly. I also wish to thank my family for their encouragement, support and forbearance. To my parents, Nico and Hettie, thank you for providing me with a foundation in life unmatched by any other. To our extended family in South Africa, thanks for your love and patience. To pastor Rich Hamstra and the other members of OCRC, thank you for being our surrogate family during our stay in the USA. Finally, I thank my sons, Nicolas and Conrad, who are hving proof that human flgure modeling is best accomplished through reproduction, my wife and partner in life, Ronél, for making it so pleasurable, and the Lord God for making it all possible. ill Vita 25 September 1961 .......................Bom in Pretoria, South Africa 1983 ...............................................B.Sc.
