Graph-based Computation of Voronoi Diagrams on Large-scale Point-based Surfaces
Bletterer, Arnaud; Payan, Frédéric; Antonini, Marc (The Eurographics Association, 2022)We present an original algorithm to construct Voronoi tessellations on surfaces from a set of depth maps. Based on a local graphbased structure, where each local graph spans one depth map, our algorithm is able to compute ... -
Towards the Reconstruction of Wide Historical Sites: A Local Graph-based Representation to Resample Gigantic Acquisitions
Bletterer, Arnaud; Payan, Frédéric; Antonini, Marc; Meftah, Anis (The Eurographics Association, 2018)Nowadays, LiDAR scanners are able to digitize very wide historical sites, leading to point clouds composed of billions of points. These point clouds are able to describe very small objects or elements disseminated in these ...
