FVoronoiDiagramField

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

Unreal Engine C++ API Reference > Runtime > Voronoi > Voronoi

References

   
Module Voronoi
Header /Engine/Source/Runtime/Experimental/Voronoi/Public/Voronoi/Voronoi.h
Include #include "Voronoi/Voronoi.h"

Syntax

class FVoronoiDiagramField

Remarks

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
