WebComputing 3D Clipped Voronoi Diagrams on GPU. An efficient GPU implementation to compute clipped Voronoi diagrams in 3D volume. Isotropic Surface Remeshing without Large and Small Angles. A novel algorithm for isotropic surface remeshing which progressively eliminates obtuse triangles and improves small angles. ... WebNov 1, 2005 · The Voronoi diagram construction in GPU is simple. At first, we subdivide the space into subspaces by GPU. Then for each Voronoi site, distance between a subspace, called a voxel, and the site is calculated and compared with the shortest distance stored in the voxel. Each voxel keeps the shortest distance and the region ID it belongs. short powder dipped nails

VoroCrust: Voronoi Meshing Without Clipping

WebThe Voronoi diagram is a fundamental geometry structure widely used in various fields, especially in computer graphics and geometry computing. For a set of points in a compact 3D domain (i.e. a finite 3D volume), some Voronoi cells of their Voronoi diagram are infinite, but in practice only the parts of the cells inside the domain are needed, as when … WebJun 10, 2009 · The most effecient algorithm to construct a voronoi diagram is Fortune's algorithm.
