Detailed Description

Stores the light attenuation(s) of the current environment.

This element stores the light attenuation(s) of the current environment. This used to set up subsequent light sources. The attenuation is stored as an SbVec3f, where the first component of the vector is the quadratic term of the attenuation, the second is the linear term, and the third is the constant.
