David Coeurjolly

Directeur de recherche

Biography

I am Directeur de Recherche CNRS at LIRIS in the Origami team. Director of the Groupement de Recherche (GdR) Informatique Géométrique et Graphique, Réalité Virtuelle et Visualisation. Co-lead of the PEPR ICCARE. General chair of the Graphics Replicability Stamp Initiative. Co-founder of the DGtal library. My main focus is digital geometry, geometry processing and point sampling for Monte Carlo rendering.

Geometry Processing Cmake Recipes

This repository contains cmake/CPM recipes that I use to easily integrate geometry processing libraries and utilities to my c++ projects. When included in your CMakeLists.txt script, cmake will automatically download the deps and prepare the targets.
