violet is a hobby project for experimenting new rendering techniques with 🦀Rust and 🌋Vulkan. Currently it features:

• A ReSTIR-based hybrid-renderer, with real-time ray-traced GI
• SVGF/ReLAX style denoiser, filtering indirect diffuse and specular separately
• Spatial Hash Grid world radiance cache (scratch)
• Reference Path tracer
• glTF model loading
• Render graph (scratch)

(Sponza rendererd with violet-restir)

• restir_renderer.rs: render passes for ReSTIR-based indirect lighting.
• shaders

Firstly, you need to install Rust and, if necessary, the Vulkan driver for your graphics card (e.g. nvdia).

Then, you can build and run the violet-restir app to view the "Sponza" model:

cargo run --bin violet-restir --release -- "./assets/Sponza/Sponza.gltf"

This project benefits from a bunch of wonderful open-source projects, including:

• ash: thin and simple, should be your go-to rust binding for Vulkan!
• egui: lovely ImGUI written in pure rust.
• puffin: easy to use profile for Rust (it also comes with a integration with egui👏)
• rspirv-reflect: minimalism SPIR-V reflection libray.
• MinimalAtmosphere: single-file atmospheric scattering implementation from Felix Westin.

And special thanks to @h3r2tic for his brilliant 💡kajiya, which inspired this entire journey into Rust and Vulkan rendering.
