Oni : a DirectX 12 renderer written in C++

Oni is a modern graphics engine written in C++ with the DirectX 12 API. Its goal is to showcase the latest advancements in real-time rendering. Oni makes heavy use of compute shaders to accelerate the rendering pipeline -- everything that isn't a draw call is done through compute.
