M.Sc. Dissertation

Acompanhamento de Raios Otimizado para Solidos CSG.

M.Sc. Dissertation, Federal University of Rio de Janeiro. Rio de Janeiro, Brazil. April 1991.

This work presents a new approach to accelerate the Ray Tracing algorithm, well-known in Computer Graphics by high realism images. A new proposal is presented for CSG solids using Spatial Subdivisions (Octrees). An hybrid structure between CSG and Octree is used, and the visualization process is enhanced using a new algorithm called Cell-Progression, which is a generealization of the Bresenham algorithm for 3D with cells of different sizes.
