An Octant Structure For Three-Dimensional Objects
Tianwen Zhang, LiZhongrong Li · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1987
This paper describes an octant structure for three-dimensional objects. A direct proce-dure for encoding larger octant belonging to an object is presented. Operators associated with octants are provided. Union, intersection, and complement of octants encoded objects are computed. Finally we develop data structures for octant operating.
