Ambient CSS v3 brings Blender-style physics-based lighting to CSS

Ambient CSS v3 – Blender meets CSS

Ambient CSS v3 is a physics-based lighting system for CSS that lets developers control light direction, material finish (matte, glass, brushed metal, etc.), and edge treatments like chamfers and fillets — all via CSS custom properties. The demo site shows real-time relighting as you move your pointer. The post doesn't disclose browser support or performance cost, but the demo runs on Vercel as a pure frontend solution.
