AcceleratedRaytracing3

Another video from my engine, that utilizes power of both rasterization and ray tracing in real time. This time cornell box and global illumination solution.

@masterxilo GI is done similar way instant radiosity does it (shoot photons to scene and thus find virtual point lights), although it does generate secondary shadows for global illumination (here comes the power of raytracer) and at last comes gathering part (where comes deferred shading on GPU in hand, because deferred shading is very good solution if you have plenty of lights in scene (especially smaller ones, like these virtual point lights).

@VilemOtte0901 And how's the GI done? Is it raytraced? And the shadows?

Let me know when the demo is ready ;) !

@masterxilo I'm currently preparing demo with paper for this kind of realtime GI, but I don't know when it'll be ready (in real game scene) as I have to do all in my spare time and recently I've been a bit too much busy.

It is based upon hybrid rendering (using rasterizer and raytracer together, to achieve high performance and high quality result), and no CUDA (nor platform specific stuff) is included, raytracing part is done on CPU, shading + rasterization on GPU

This is very interesting, strange that it has so few views/comments. Is your program and or maybe even the code available? How does it work? Does it use CUDA? Or only GLSL? Is it general purpose, does it support triangles?
