Overview

The Scalar to vector node converts the Input scalar into a vector. This conversion happens according to the node input type conversion rules which are described in the Node Input Type Conversion documentation.

When converting a scalar to a vector, each component of the vector is simply set to the value of the scalar :

vector.x becomes scalar
vector.y becomes scalar
vector.z becomes scalar

These nodes have no other settings apart from the Input node.

Settings:

• Name: This setting allows you to apply a descriptive name to the node, which can be helpful when using multiple Scalar to Vector nodes in a project.
• Enable: When checked, the node is active and the conversion operation will take place. When unchecked the values assigned to its Main Input, if any, are passed through, otherwise a value of 0 is passed through.

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.

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

Literally, to change the position of something. In graphics terminology to displace a surface is to modify its geometric (3D) structure using reference data of some kind. For example, a grayscale image might be taken as input, with black areas indicating no displacement of the surface, and white indicating maximum displacement. In Terragen 2 displacement is used to create all terrain by taking heightfield or procedural data as input and using it to displace the normally flat sphere of the planet.

A shader is a program or set of instructions used in 3D computer graphics to determine the final surface properties of an object or image. This can include arbitrarily complex descriptions of light absorption and diffusion, texture mapping, reflection and refraction, shadowing, surface displacement and post-processing effects. In Terragen 2 shaders are used to construct and modify almost every element of a scene.
