Notes on Rayshade - 3 - Lighting and Atmospheric Effects

Rayshade provides a number of different light source types, from the simple "point" light to the much more computationally intensive "area" light.

For each type of light you must specify the intensity, this is either a red- green-blue triple indicating the colour of the light or a single value (providing "white" light).

If no light source is specified, a directional light with an intensity of 1.0 with a vector of (1, -1, 1) is used [Rayshade User's, Guide Chapter 4].

Note that the light sources themselves are always invisible!


Ambient Light

        light intensity ambient
The "background" light present in a scene, there can be only one ambient light, if more than one are defined the last is used.
