CalculateVoronoi() [1/2]

static JobHandle CalculateVoronoi ( NativeArray< float2 > points, ref NativeArray< NativePolygon2D > polygons, ref NativeArray< int > polygonSites, out JobAllocations allocations, Allocator allocator = Allocator::TempJob, float addedMargin = 1::0f, float epsilon0 = 10e-8f, float epsilon1 = 10e-6f, JobHandle dependsOn = default )

static

Calculates and returns the polygons that form a Voronoi Diagram by forming the dual graph of the delaunay triangulation. A job is scheduled to calculate the bounding rectangle.

Parameters

points	The sites of the voronoi diagram
polygons	An array that is filled with the resulting polygons. Its length should be equal to the number of points
polygonSites	An array that is filled with integers for each polygon. Each integer corresponds to the site the polygon belongs to
allocations
allocator
addedMargin	Additional margin space for the boundary
epsilon0	The error rate for forming the dual graph
epsilon1	The error rate for boundary intersections
dependsOn

Returns

CalculateVoronoiLookupTable() [1/2]

static JobHandle CalculateVoronoiLookupTable ( int2 dimension, NativeArray< float2 > points, ref NativeArray< int > table, out JobAllocations allocations, Allocator allocator = Allocator::TempJob, float addedMargin = 1::0f, JobHandle dependsOn = default )

static

Calculates a Voronoi Lookup Table (VoLT) with a certain dimension. A job is scheduled to calculate the bounding rectangle.

Parameters

dimension	The dimension in X and Y (similar to a texture resolution)
points	The sites of the voronoi diagram
table	The table is returned after the scheduled Job is completed
allocations
allocator
addedMargin	Additional margin space for the boundary
dependsOn

Returns
