Lloyd 3D

Dependencies

This node requires SciPy library to work.

Functionality

This node uses Lloyd algorithm to redistribute a set of points in 3D space (XOY plane) uniformly inside bounding box or bounding sphere.

Optionally, weighted Lloyd algorithm can be used, to put points more dense in places to which higher weight is assigned.

Inputs

This node has the following inputs:

• Sites. Initial points to be redistributed. This input is mandatory.

• Clipping. Clipping distance for Voronoi diagram. This value will be added to size of bounding box or sphere. The default value is 1.0.

• Iterations. Number of Lloyd’s algorithm iterations. The default value is 3.

• Weights. Scalar Field object used to assign different weights for different places in 3D space. More points will be put in places which have bigger weight. This input is optional. If not connected, uniform Lloyd algorithm will be used.

Parameters

This node has the following parameters:

• Bounds mode. This defines bounding shape of generated points. The available options are:

  • Bounding box

  • Bounding sphere.

  The default value is Bounding box.

Outputs

This node has the following output:

• Sites. Redisrtibuted points.

Example of Usage

• Spacial-> Vector P Field

• Viz-> Viewer Draw
