Lightsprint - realtime global illumination
About Lightsprint

Lightsprint was a world leader in realistic realtime lighting middleware.

Lightsprint SDK is a multiplatform middleware for C++ developers:
  • realtime global illumination offers the most realistic realtime lighting with freely moving lights
  • global illumination precalculation builds lightmaps and more in scenes with static lights

Lightsmark Lightsmark 2008 - lighting benchmark powered by Lightsprint SDK. Realtime radiosity, color bleeding, penumbra shadows.

Lightsprint SDK has helped us create realistic lighting quickly and with minimal effort. It has become an integral part of our pipeline for next-gen games.
