Here are some codes/softwares related to digital or computational geometry.


Digital surface decomposition into digital planes




Simplification of a digital curve



Fast computation of the characteristics of a Digital Straight Line Subsegment



Union of Digital Straight Segments

  • Implementation of the algorithm presented in "Algorithms for Fast Digital Straight Segments Union". Isabelle Sivignon, International Conference on Discrete Geometry for Computer Imagery 2014, Springer LNCS 344-357. It computes the minimal characteristics of the digital straight line containing two given digital straight segments. The code is part of the DGtal library, as a method of the class ArithmeticalDSS.
