Profile

A photorealistic Moon viewer running entirely in the browser. WebGPU primary renderer with WebGL 2 fallback.- NASA CGI Moon Kit textures served via a quadtree LOD tile system - Oren-Nayar BRDF (lunar regolith is non-Lambertian with strong backscatter) - Sun position calculated from astronomy-engine (±1 arcminute) - Scrub through the full lunation cycle or watch in real time - Earth and Tycho-2 starfield in the backgroundTech: Three.js with TSL shaders (compile to both WGSL and GLSL), React Three Fiber, Vite. The shading model was the most interesting part — standard PBR looks completely wrong for the Moon because regolith doesn't have a specular lobe; it actually gets brighter at opposition
