Smooth Voronoi 3D Cel Colour


This node generates Voronoi noise and outputs the noise value as colour data. Voronoi noise has the appearance of being divided up into different cells. This node assigns a different colour 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:

This node requires a Get position, Get position in geometry, or Get position in texture function node to be assigned to its Main input so that the current render state knows where a sampled point is located in texture space.

  • Name: This setting allows you to apply a descriptive name to the node, which can be helpful when using multiple Smooth Voronoi 3D Cell Colour nodes in a project.
  • Enable: When checked, the node is active, and when unchecked the node is ignored.
  • Scale: This setting controls the overall scale of the noise pattern generated. Increasing the scale value makes it seem like the cells in the noise pattern are larger.
  • Seed: The setting controls the noise pattern generated. Each seed value generates a slightly different pattern.

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.
