Node Description & Purpose:
The Dot product node takes the Input and Input 2 vectors and outputs the dot product of the two vectors, which is a scalar value. The dot product is the cosine of the angle between the two input vectors.
Node Type: Function
Settings:
This node has just the one setting, which lets you choose a node for Input 2.
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.
A scalar is a single number. 1, 200.45, -45, -0.2 are all examples of scalar values.
