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. Webof Voronoi seeds. This enables VoroCrust to protect all sharp features, and mesh the surface and interior into quality el-ements. We demonstrate the performance of the algorithm through a variety of challenging models, see Figure 5, and compare against state-of-the-art polyhedral meshing methods based on clipped Voronoi cells; see Figures 1 and 2.
