Boolean operations between extended octrees

This paper describes the Extended Octree model that are an exact representation for polyhedra. Boolean Operations in this model perform in linear time, as they include an implicit spacial localization of the objects. As a consequence, Extended Octrees can be used as a secondary model for performing...

Descripción
Sumario:This paper describes the Extended Octree model that are an exact representation for polyhedra. Boolean Operations in this model perform in linear time, as they include an implicit spacial localization of the objects. As a consequence, Extended Octrees can be used as a secondary model for performing boolean operations in Geometric Modeling Systems. The purpose of this paper is to present and discuss the algorithms for boolean operations using the Extended Octree representation.
