Multiply Complement Scalar

Overview

The Multiply Complement family of nodes allow you to multiply the colour/scalar coming into the Main Input by the complement of the color/scalar coming into Input 2.

The multiplication is component-wise, for example with a colour:

Main Input.red multiplied by the complement of Input 2.red
Main Input.green multiplied by the complement of Input 2.green
Main Input.blue multiplied by the complement of Input 2.blue

The complement of a component value can be derived by subtracting the component value from the maximum possible value. For example, the pixel values in a greyscale image range from 0 - 255. The complement of a pixel value of 100 is 155. Likewise the complement of a pixel value of 0 is 255, and a pixel value of 255 is 0.

The effect of the Multiply complement scalar node on an texture map assigned to an Image shader.

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

A single element of an image which describes values for color and/or intensity, depending on the color system which the image uses. Groups of ordered pixels together form a raster image.

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 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.
