Design Goals

• An easy to use cross platform graphics/compute/os api for rapid development.
• Hot reloadable, live coding environment (shaders, render graphs, code).
• Concise low level graphics api... think somewhere in-between Metal and Direct3D12.
• High level data driven graphics api for ease of use and speed.
• A focus on modern rendering examples (gpu-driven, multi-threaded, bindless, ray-tracing).
• Flexibility to easily create and use different rendering strategies (deferred vs forward, gpu-driven vs cpu driven, etc).
• Hardware accellerated video decoding.
• Fibre based, multi-threaded, easily scalable to utilise available cpu and gpu.
• Data-driven and configurable.
• Plugin based and extendible...

Roadmap

In Progress

• Debug / Primitve Rendering API
• High level graphics api (render graphs, data driven, Uber shaders)
• Multi-threading support (async command buffer generation and job dispatches)
• ~~API (gfx::, os::) / Backend (d3d12::, win32::)~~
• ~~API (av::) / Windows Media Foundation (HW Video / Audio Decoding)~~
• ~~Imgui support w/ Viewports~~

Future Plans

• Hot reloading
• Samples and Demos
• Linux
• Vulkan
• macOS
• Metal
• AV Foundation
• WASM
• WebGPU

Contributing

Contributions of all kinds are welcome, you can make a fork and send a PR if you want to submit small fixes or improvements. Anyone interseted in being more involved in development I am happy to take on people to help with project of all experience levels, especially people with more experience in Rust. You can contact me if interested via Twitter or Discord.
