Computing 3d clipped voronoi diagrams on gpu
WebVolumetric PolyCube-Map-based methods offer automatic ways to construct all-hexahedral meshes for closed 3D polyhedral domains, but their meshing quality is limited by the lack of interior singularities and feature alignment. In the presented work, we propose **cut-enhanced PolyCube-Maps**, to introduce essential interior singularities and preserve … WebAbstract. We propose a GPU algorithm that computes a 3 D Voronoi diagram. Our algorithm is tailored for applications that solely make use of the geometry of the Voronoi cells, such as Lloyd's relaxation used in meshing, or some numerical schemes used in fluid simulations and astrophysics. Since these applications only require the geometry of ...

WebOct 6, 2024 · 1. Introduction. Key motivation for the generation of Voronoi diagrams is the analysis of spatial data and, therefore, generalized Voronoi diagrams find application in various scientific disciplines whenever closest-point associations or proximity based spatial partitioning are involved: E.g., ranging from graph labeling [] and voxelization [] over … WebJun 10, 2009 · The most effecient algorithm to construct a voronoi diagram is Fortune's algorithm. It runs in O (n log n). Here is a link to his reference implementation in C. Personally I really like the python implementation by Bill Simons and Carson Farmer, since I found it easier to extend.
