Voronoi 3D Cell Scalar

Node Description & Purpose:
This node generates Voronoi noise and outputs the noise value as a scalar. Voronoi noise has the appearance of being divided up into different cells. This node assigns just one value to each cell in the generated noise, which gives a mosaic like appearance. Here is an example of the noise pattern generated by the node:

Node Type: Function

Settings:

  • Scale: The scale setting controls the overall scale of the noise pattern generated. Increasing the scale value make it seems like the cells in the noise are larger.
  • Seed: The seed value controls the noise pattern generated. Each seed value generates a slightly different pattern.

A scalar is a single number. 1, 200.45, -45, -0.2 are all examples of scalar values.

A single object or device in the node network which generates or modifies data and may accept input data or create output data or both, depending on its function. Nodes usually have their own settings which control the data they create or how they modify data passing through them. Nodes are connected together in a network to perform work in a network-based user interface. In Terragen 2 nodes are connected together to describe a scene.
