Gael Engine - Fun with Lights
After extending the spotlights in the engine, it is now possible to change the aspect-ratio of the spot cones. After that, I've created a simple test scene, which you can see in the video.
Every light casts shadows and for every light, indirect lighting is computed in realtime. The indirect lighting data is stored inside a 3D-texture. It is not the fastest way (completely done on the CPU), but it runs with about 20FPS with 3 active and changing lights. But the grid resolution is not very high - so do not ask for special magic - there is none.
