# 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.

## DISCLAIMER

This is an experimental renderer as I am currently learning graphics programming. Please take this into consideration when reading the code for this renderer.

## Requirements

- [xmake](https://xmake.io/#/)
- Windows SDK Latest
- Visual Studio 2022 + ATL Toolkit
- HLSL Shader Model 6.6
- GPU with, ideally, the following features:
    - DXR
    - Mesh shaders
    - Work graphs

## Building

- xmake
- xmake f --mode={debug/release}
- Copy the contents of the bin folder in build/windows/x64/{debug/release}/
- Copy the D3D12 folder in build/windows/x64/{debug/release}/
- xmake run
