Voronoi Split cuts geometry according to a set of polylines. Each line describes a cut along its mid point. Lines are best created with the Tetrahedralize SOP.
Subset of the input geometry to split.
Clip Points Group
Lines leaving these points will be used as clipping lines. Each point will correspond to a new piece.
Instead of cutting at the mid point, it is offset by this percentage along the line.
Create Interior Surfaces
The interior faces of cutting the polygons are created. This requires the input be a closed watertight manifold.
Transfer Attributes to Interior Surfaces
Transfers attributes from adjacent primitives when constructing the interior surfaces.
Stamp Pieces with Point Numbers
Creates attributes storing the original point number and piece number. This allows one to build a stable correspondence between your input points and the resulting polygons.
When enabled, the specified float attribute provides a "weight" for each point.
Specifies how the Weight Attribute is used to place the cutting planes.
The cutting plane for each connected pair of points will be placed such that the ratio of the distances from each point will be the same as the ratio of the weights. The plane will be closer to points with smaller weight and farther from points with larger weight.
This example demonstrates using the Weight Attribute option on the Voronoi Split SOP to create a power diagram.
