“Techniques for the Generation of Three Dimensional Data for Use in Complex Object Synthesis,” The Ohio State University Department of Computer and Information Science, 1982.
My own dissertation research was centered around investigating and implementing new approaches to the creation and specification of three dimensional data for us in image generation. It built on a system created by Rick Parent of CGRG, and included a surface patch intersection algorithm that utilized the Catmull subdivision scheme made famous by Ed Catmull at the University of Utah. The resulting algorithms and system implementation, called DG2, were used in scene creation at the Computer Graphics Research Group at Ohio State, and later became the heart of the modeling environment at Cranston/Csuri Productions, Inc. Below are some sample images that were created for the dissertation or for related research projects that show the complexity of the models created with DG2.
