Node Description & Purpose:
The Exp family of nodes output the natural logarithm value of the Input value.
For colours the calculation is done on a component-wise basis, for example:
Output.red = log of Input.red
Output.green = log of Input.green
Output.blue = log of Input.blue
Node Type: Function
These nodes have no other settings apart from the Input node.
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.
