Water Shader

Node Description and Purpose: The Water Shader is specifically designed to provide a realistic water effect on Terragen 2 surfaces, including wave-shaped displacement, reflectivity, and transparency. Specialized controls are provided to realistically simulate certain water phenomena, for example "wind patchiness".

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.
