Bias Scalar

Node Description & Purpose: The Bias scalar node creates a curve, the shape of which depends on the Bias value. The output of the node is the value of the bias curve corresponding to the Input value. Here's a graph showing the bias curve at two different Bias values:


The output value will be between 0 and 1. The node expects both the Input and Bias values to be between 0 and 1. It does clamp these values to make sure that they are within that range.

Node Type: Function


  • Bias: The value defining the shape of the bias curve, as in the graph above.

Error conditions:

  • It is an error for there to be no Input value. In that case 0 is output from the node.
  • It is an error for there to be no Bias value. In this case the Input value will be output.

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.
