"Ephemeris 2" is a highly-optimized skydome system that accurately depicts realistic sky and clouds for real-time games or graphics applications. It features a dynamic 24-hour time cycle comprising sunrises, sunsets, blue sky, and shimmering moon. It supports atmospheric sun scattering using a rendering model based on physical properties, as well as astronomically-correct simulations of sun, stars, and moon. Other features employed by this system include God Rays, Aerial Perspective, dynamically lit volumetric clouds and more. A custom-tailored version of this system shipped with the game Stormland by Insomniac. This presentation will describe a variety of graphics techniques employed by this system and the optimizations necessary to bring them to real-time performance.
