Blue to Scalar
Node Description & Purpose:
The Red/Green/Blue to scalar nodes all take a colour as input and output the respective colour component as a scalar. For example, the Red to scalar node will output the red value of the input colour.
Node Type: Function
This node has no other settings apart from the Input node.
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.
