Summary: add comment in planet2.cfg for atmosphere2 arguments
Created: 2008–12–04 11:01
Status: Released
Category: Request

Version: 2.0

Description:
there is a comment describing the arguments for the atmosphere option to planet2, but the new atmosphere2 syntax is not commented to explain what the arguments are.
frankie October 19, 2012, at 01:20 PM: Unlike the atmosphere command, atmosphere2 replaces the "exponential" and "linear" terms with a single "density_falloff_exponent" term that defines how fast the density of the atmosphere falls to zero.
# atmosphere2( surface_density, end_elevation, sR, sG, sB [, density_falloff_exponent [, aRatio, aR, aG, aB] ] )
# /* surface_density = amount scattered per unit volume at the planet's surface */
# /* end_elevation = altitude above planetary elipsoid where the atmosphere density falls below 0.1% of density at the planet's surface */
# /* density_falloff_exponent = the exponent used in computing rate of density falloff (linear = 1.0) */
# /* s(RGB) = normalized scattered color */
# /* aRatio = absorbtion to scattering ratio */
# /* a(RGB) = normalized absorbed color */
This was also added in planet2_earth.cfg as a comment.
