Data Fields  
float  pos [3] 
float  color [3]

J. Preetham, Peter Shirley and Brian Smits. Siggraph 1999. Note that the original implementation for Stellarium fixed turbidity T=5 and tweaked a few color parameters for a betterlooking sky. When T is set to deviate from 5, the original parameters appear overall better.
