Skyfall-GS – Synthesizing Immersive 3D Urban Scenes from Satellite Imagery

Harder, Better, Faster, Stronger Version of Uber H3 in Rust

I’ve been experimenting with Rust lately and wanted a project that would help me explore some of its lower-level and performance-oriented features. Inspired by Sebastian Lague’s videos, I decided to implement my own ray tracer from scratch.The initial goal was just to render a simple 3D scene in the browser at a reasonable frame rate. It evolved into a small renderer that can:
 • Run locally or on the web using wgpu and WebAssembly
 • Perform mesh rendering with a Bounding Volume Hierarchy (BVH) for acceleration
 • Simulate both direct and indirect illumination for photorealistic results
 • Be deployed easily as a free web demo using GitHub PagesThe project is far from perfect, but it’s been a fun way to dig deeper into graphics programming and learn more about Rust’s ecosystem. I’m also planning to experiment with Rust for some ML projects next.GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;tchauffi&#x2F;rust-rasterizer" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;tchauffi&#x2F;rust-rasterizer</a>
