Abstract

This paper presents an algorithm to trace discrete straight lines in regular grids of any dimension. Most known line tracing algorithms have been developed in ${\hbox{\rlap{Z}\kern 2.0pt{\hbox{Z}}}}^{2}$ and ${\hbox{\rlap{Z}\kern 2.0pt{\hbox{Z}}}}^{3}$ orthogonal grids. The contribution of this paper is the definition of a method to trace lines in nonorthogonal grids in any dimension. This method is not restricted to being used with a specific grid connectivity as other widespread methods are. Good performance can be achieved because only additions are used during line tracing.
