Detailed Description

Compute and display the daylight sky color using OpenGL.

The sky brightness is computed with the SkyBright class, the color with the SkyLight. Don't use this class directly but use it through the LandscapeMgr.

overridevirtual

Compute sky brightness values and average luminance.

Parameters

noScatter true to suppress the actual sky brightness modelling. This will keep refraction/extinction working for didactic reasons.

Implements Atmosphere.
