Node Description & Purpose:
The Cross product node takes the Input and Input 2 vectors and outputs a new vector which is normal, or perpendicular, to the plane described by the two input vectors.
Node Type: Function
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 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.
