Exp Colour

Node Description & Purpose:
The Exp family of nodes output the exponential value of the Input value. The exponential value is the mathematical constant e raised to the power of the Input value i.e. e to the power of Input. e has a value of approximately 2.7182818.

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

Output.red = e to the power of Input.red
Output.green = e to the power of Input.green
Output.blue = e to the power of Input.blue

Node Type: Function

Settings:
These nodes have no other settings apart from the Input 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..
