Overview

This project showcases a GPU-based raytracer written in Rust for the browser. My goal was to create a simple, streamlined, and responsive renderer. Krust uses a highly optimized BVH to make traversing large models a breeze, and leverages MIS to enhance convergence. I opted for .glb files to simplify GPU data transfers and to ensure accessibility through a widely adopted file format.

Tech Stack:

• Rust: Core programming language.
• Wasm-bindgen: Facilitates communication between WebAssembly and JavaScript.
• React: Used for building the frontend user interface.
• Wgpu: WebGPU implementation in Rust, enabling high-performance graphics and computation.

Future Improvements Currently in Development:

• Subdivision (Catmull-Clark and adaptive)
• Subsurface scattering (diffusion and random walk)
• Volumes
• Radiance caching

Usage

Try out a sample scene on the website. Be sure to enable WebGPU in your browser.

To build and run the project locally, follow these steps:

1. Clone the repository:

   git clone https://github.com/krrud/krust-gpu.git
   cd krust-gpu

2. Build and run the project:

   cargo run
