Real-time GPU path tracing: Unbiased Cab City WIP 1

Found some time to do another quick instancing test with OTOY's Brigade engine:

- 1024 dynamic instances of a car (materials can be customized per instance, not shown yet)

- car model contains about 23k triangles

- 400k triangle city scene (can be instanced tens of times without performance loss)

It's now also possible to have a complete city with hundreds of instanced city blocks containing thousands of (instanced) animated characters and cars, essentially a real-time path traced photorealistic GTA. It's mighty impressive. But that's for another video :)

UPDATE: Yes! Ich bin mit diesen Demo auf die grossen Deutschen website PC Games Hardware erschenen, das ist ja ganz toll! :D : http://www.pcgameshardware.de/Raytracing-Hardware-255905/News/Brigade-Engine-Raytracing-GTA-Stil-1040284/
