Get Specular Colour

Get Specular Colour

Provides the "Specular Colour" of the current Render State. The Render State is affected by any shaders which were called before this function is called, among other things.

Specular Colour is the additive component of the appearance of a surface which was reflected from light sources by an amount that strongly depended on the viewing angle, surface normal and light direction. Usually this comes from "specular highlights" settings in the GUI. It is not the specularity of the surface, but the final specular contribution at that point. Currently, ray traced reflections and transmissions are not stored in the specular component, but this may change in future.

The Input connection is not used by this node.

Graphical User Interface, a general term that refers to the interface of any program running in a modern graphical operating system and which does not operate exclusively from the commandline.

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.
