Overview

A short preview of OTOY's Brigade 3.0 engine doing real-time path tracing, running on two GTX Titans.

On Hacker News

HN cites it as the example of real-time GPU path tracing, noting its noise problem.

What UE4 can do is very impressive. But when it comes to real time photo realism I think path tracing is even more impressive. For example this Brigade 3.0 demo: [VIDEO]

I wonder what convolutional neural networks bring to the table. Maybe you could use them to get rid of the noise, or then you could use ray tracing for the base image and train a CNN to "recolour" that image based on a noisy path traced one of the same scene. This demo is 4 years old, but the noise still seems to be a problem: [VIDEO] If anybody's got more recent impressive demos to link, I'd like to see how things have been developing.

well you COULD use OpenCL to "control every pixel". Here's an example of path tracing in "realtime" (ok, it's not quite there yet) on the GPU. [VIDEO] check out this blog too: [LINK]
