This part of the User Guide explains some of the fundamental concepts used for rendering and by shaders in Terragen 2.
Displacment[edit]
The Displacement page explains displacement.
Global Illumination[edit]
This Global Illumination|document from the Terragen 2 Reference explains global illumination (GI) and how it works in Terragen 2.
Translucency[edit]
This page explains the translucency effect available in several shaders.
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.
