Abstract

In this paper, we present a new method of discrete Ray-- Casting, using parallel rays, having the property that each point of the - scene belongs to one and only one ray. This study is based on the theory - of arithmetic discrete geometry. The rays are modeled by Figueiredo-- Reveillès' discrete naive 3D lines that tile the space and that can be - incrementally generated.
