=== Exhaust flames === | |||
The latest addition to the Atmospheric Light Scattering framework is a procedural shader effect to render thruster and afterburner exhaust flames. This effect integrates over a 3d-distribution of glowing emitters in a bounding box, which means that it doesn't generate sharp edges in the visuals. | |||
Flame color, density, distribution of shock diamonds and widening in thin atmosphere are all runtime configurable, allowing to account realistically for changed thrust or ambient pressure. | |||
Here's an example application for the Space Shuttle main engine - note how the exhaust plume is narrow early on and shows pronounced shock diamonds while it widens in the thin upper atmosphere: | |||
