Class GLSLAtmosphereFactory

java.lang.Object
  org.xith3d.effects.atmosphere.AtmosphereFactory
      org.xith3d.effects.atmosphere.GLSLAtmosphereFactory

All Implemented Interfaces:

Updatable

public class GLSLAtmosphereFactory
extends AtmosphereFactory

The AtmosphereFactory is a visual effect for spheres. It computes in real-time the atmosphere of a planet see from space.

All computations are done by the GPU using shaders.
