Brigade X
What is Brigade X?
Brigade X is a high-quality real-time noise-free path tracer.
It's had it's inception in 2019, an official announcement in 2020, a demo-release in 2021 and is scheduled to become a part of OctaneRender sometime in 2022/2023.
I was deeply involved with the rendering architecture for Brigade right from the start. I made significant contributions to Brigade's highly pipelined frame layout, its optimized scene acceleration structure management, the parallel architecture of the engine, and also built almost all of the internal tooling.
Brigade runs on a custom & highly adaptable Vulkan library - to which I made significant contributions over the years, such as its support for vulkan raytracing, descriptor management, shader & pipeline compilation, etc. While this Vulkan library is not showcase-able on a portfolio, it is worth mentioning that it exists, that Brigade X runs on it, and that I contributed significantly to it.
In late 2021 a public demo was released of Brigade X, marketed as "BrigadeBench". To release this demo, which ran on Vulkan, we needed to make sure that we could ship our GPU code securely. For obvious reasons I can't state what we did exactly to make that happen, but given Vulkan's "open" nature, you can imagine some of the challenges that we faced, and the IHV cooperation we needed.
