UPGEN Lighting is an optimized for maximum performance framework around post-effect that provides a fully dynamic approximation of Global Illumination to your games (requires no precomputations). This solution provides high execution speed, produce great visual results, and uses minimum of system resources. Emulation of indirect lighting could be made as fully automatic, in a semi-automatic way, or by manual designing light to save extra performance.
Under the hood, solution is based on the idea of making ultra-fast type of point light sources (10-20 times faster than standard ones) and using thousands of them to approximate light propagation for the scene in realtime. To achieve this we made a special kind of screen space effect, which bakes each frame hundreds of most valuable lights and applies combined lighting inside G-Buffer for current camera.
This framework provides several workflows for building lighting in your scenes. You can use such Fast Light sources to automatically transfer bounced light from standard light sources using Ray-Tracing. Or you can combine a standard type of light sources with Fast Lights to manually approximate GI in complex scenes and achieve the best performance and a beautiful visual look.
