Enlighten is the leading real time global illumination solution for game developers.
Enlighten computes diffuse indirect lighting using radiosity. Unlike other radiosity solutions, Enlighten lets you move and change lights and materials at runtime.
With Enlighten in your engine
Improve your game lighting with high-quality realistic global illumination from many dynamic light sources
Provide lighting artists with instant feedback on their lighting changes, rather than waiting hours for a bake
Give game designers the freedom to create experiences that depend on indirect lighting
No need to work around the limitations of static lighting: Enlighten delivers improved lighting quality and reduced development cost
Minimal runtime cost for static light sources, using high-quality baked lighting with real-time previews
