Add Scalar

Node Description & Purpose: The Add family of nodes allow you to add the colour/scalar/vector coming into the Input by the color/scalar/vector coming into Input 2. The addition is component-wise, for example with a colour :

Input.red + Input 2.red

Input.green + Input 2.green

Input.blue + Input 2.blue

Node Type: Function

Settings: All nodes in this family have just the one setting, which lets you choose a node for Input 2.

A scalar is a single number. 1, 200.45, -45, -0.2 are all examples of scalar values.

A vector is a set of three scalars, normally representing X, Y and Z coordinates. It also commonly represents rotation, where the values are pitch, heading and bank.

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.
