Brigade - brute force game engine

Brigade is in real-time, it’s an engine for video games. It uses path tracing to render the image; instead of rasterisation like every other 3D games.
Brigade uses path tracing, which is an extension to the ray tracing algorithm capable of producing photorealistic images. It traces many rays (samples) per pixel in random directions, and then takes the average value to calculate the final color of each pixel.
Whenever a ray hits a surface, a new ray is traced from that hitpoint in a random direction until the max path depth is reached or until a Russian roulette-like mechanism kills the ray.
This way, path tracing is able to produce effects like diffuse color bleeding, glossy (blurry) reflections, true ambient occlusion, soft shadows, caustics, true depth of field, etc.
It can simulate every known material including participating media like fog, god rays and clouds and materials with sub-surface scattering for example.
