Voronoi on Solid

+https://user-images.githubusercontent.com/14288520/202746548-02f2525f-f34b-44cf-9054-fd5ce9697ca6.png +
+

Dependencies

+

This node requires both SciPy and FreeCAD libraries to work.

+
+
+

Functionality

+

This node creates Voronoi diagram on a given Solid object. The result can be +output as either series of fragments of the shell of Solid object (series of +faces), or as a series of solid bodies.

+

Note: this node uses FreeCAD’s functionality of solid boolean operations +internally. This functionality is known to be slow when working with objects +defined by NURBS surfaces, especially when there are a lot of sites used. Also +please be warned that this functionality is known to cause Blender crashes on +some setups.

+

Inputs

+

This node has the following inputs:

+
    +
  • Solid. The solid object, on which the Voronoi diagram is to be generated. +This input is mandatory.

    +
  • Sites. List of points, for which Voronoi diagram is to be generated. This +input is mandatory.

    +
  • Inset. Percentage of space to leave between generated Voronoi regions. +Zero means the object will be fully covered by generated regions. Maximum +value is 1.0. The default value is 0.1. This input can consume either a +single value per object, or a list of values per object - one value per site. +In the later case, each value will be used for corresponding cell.

+

Parameters

+

This node has the following parameters:

+
    +
  • Mode. The available options are available:

    +
      +
    • Surface. The node will split the surface (shell) of the solid body into +regions of Voronoi diagram.

    • +
    • Volume. The node will split the volume of the solid body into regions +of Voronoi diagram.

    • +
    +

    The default value is Surface.

    +
  • Flat output. If checked, output single flat list of fragments for all +output solids. Otherwise, output a separate list of fragments for each solid. +Checked by default.

  • +
  • Accuracy. This parameter is available in the N panel only. Precision of +calculations (number of digits after decimal point). The default value is 6.

+
+

Outputs

+

This node has the following outputs:

+
    +
  • InnerSolid. Solid objects (or their shells, if Surface mode is used) +calculated as regions of Voronoi diagram.

  • +
  • OuterSolid. Solid object, representing the part of volume or shell, which +is left between the regions of Voronoi diagram. This object will be empty if +Inset input is set to zero.

  • +
+
+
+
