=== Atmospheric light scattering === | |||
The ALS rendering framework introduces improved support for rendering cockpit interiors. | |||
==== Environment-responsive glass ==== | |||
A new glass effect for the cockpit interior brings dynamical rendering of raindrop splashes as well as frost. A cube-map reflection of the cockpit interior is also supported. In the future, the effect will also include fogging and windshield wiper support with aircraft-supplied texture masks, all with a realistic interaction with the sunlight, including the enhanced visibility of dirt on glass when looking into the sun due to Mie scattering. | |||

Both frost and the correct splash dynamics of the raindrops need to be modeled airplane side, as the shader can not have the required information. Details to appear on [[ALS technical notes]]. | |||
==== Cockpit interior light and shadow ==== | |||
Do you like the way shadow and light move across the panel in flight when using Rembrandt? ALS is now able to do the same and more using the new model-interior effect which utilizes a cubemap representing the cockpit layout - at hardly any framerate cost. The effect allows to draw very sharp shadows without flickering, semi-shadows and dirty glass, tinted glass and even to render caustics from light refracted on curved glass surfaces: | |||

All that's needed from airplane modelers is a pre-computed cubemap representing the cockpit. | |||

After lots of hard work by Torsten D, a new, more compact [[fgdata]] repository ([[Base Package]]) has now been created. Located at http://sourceforge.net/p/flightgear/fgdata/, this new fgdata has had all aircraft (except for the [[C172p]] and [[UFO]]) stripped from it, as well as the histories of the Scenery, AI, and Models directories<ref name="multiple">{{cite web | After lots of hard work by Torsten D, a new, more compact [[fgdata]] repository ([[Base Package]]) has now been created.
