Shader Family: Light

Output: Color

The mib_cie_d light shader utility is used to determine a color for a light source. It is connected to the color parameters of other light shaders.

The Comission Internationale de l'Eclairage (CIE) has standardized several illuminants. The most well known of these is called D65, but there is an entire range of CIE D illuminants. The number 65 refers to the associated color temperature of 6500 Kelvin. This illuminant describes the color of daylight with an overcast sky which is widely used to define the color white, and its sRGB coordinates are (1,1,1). The other CIE D illuminant differ from D65 by the associated color temperature. This implementiation supports color temperatures from 4000 Kelvin to 25000 Kelvin.

Name	The name of the shader node displayed in the render tree. Enter any name you like, or leave the default.
temperature	The associated color temperature of the CIE D illuminant in degrees Kelvin. The allowed range is from 4000 to 25000 Kelvin (the default is 6500 Kelvin).
intensity	Determines the intensity of returned color (the default is 1).
