'''Atmospheric Light Scattering''' | |||
[[Atmospheric light scattering]] is an alternative rendering framework, containing its own set of effects and shaders focusing on rendering realistic environment-dependent fog and light computations for clouds and terrain. The simulation includes | |||
* Rayleigh, Mie and diffuse multiple scattering of light in the atmosphere, on haze and on clouds | |||
* a volumetric ground fog simulation | |||
* realistic ambient and diffuse light curves for sunset and sunrise conditions measured from a large collection of photographs | |||
* a simple moonlight illumination model | |||
Together with Advanced Weather, it functions as an integrated environment simulation in which the individual elements mutually influence each other. For instance | |||
* clouds and winds are influenced by the distribution of terrain elevation | |||
* prevailing winds, terrain slopes and stability of the lower atmosphere determine the shape of visible clouds | |||
* cloud layers and haze influence color and intensity of light reflections | |||
* winds influence wave patterns on water | |||
* light at sunrise and sunset is position and altitude dependent, allowing for phenomena such as Alpenglow or brightly illuminated high-altitude clouds while the ground is dark | |||
For more powerful graphics cards, the framework includes procedural terrain texturing, including features such as | |||
* terrain slope dependent non-tiling texturing | |||
* hires close-up texturing effects with up to 10 cm detail resolution and dynamically added bumpmap for low-level flight | |||
* terrain appearance changes with user-controlled environment, terrain may appear wet and covered in puddles, dry and dusty, moss-overgrown or covered in a snow-layer of adjustable thickness, all of which respect terrain slope where appropriate. | |||
