Difference Colour

Node Description & Purpose:
The Difference family of nodes finds the difference of the two input values. The difference is the absolute value of the Input value minus the Input 2 value:

Output = absolute value of( Input minus Input 2 )

For more information about absolute values, see the documentation for the Abs Colour nodeA 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..

For colours the calculation is done on a component-wise basis, for example:

Output.red = difference of Input.red and Input 2.red
Output.green = difference of Input.green and Input 2.green
Output.blue = difference of Input.blue and Input 2.blue
