FVoronoiDiagramField

Use a Voronoi diagram to support faster querying of Voronoi-like data from arbitrary sample points:

API > API/Runtime > API/Runtime/Voronoi

Use a Voronoi diagram to support faster querying of Voronoi-like data from arbitrary sample points:

  • Distance to closest point
  • ID of closest point
  • IDs of closest two points
  • Distance to closest Voronoi cell boundary (not considering bounding box walls)

Note: Queries are only thread safe if each thread has its own FVoronoiComputeHelper
