From the README

A composable, distance-estimated 3D fractal engine for the browser. You build a fractal by ordering small primitive operators (box fold, sphere fold, scale, rotate, kaleido, Mandelbulb power, …) into a formula; the engine packs that formula into a GPU buffer and renders it live with WebGPU.

No build step. No dependencies. core/ is pure ES modules — drop it on any static host and import it. There is nothing to compile.

### ▶ Live demo Drag to orbit · scroll to zoom · pick a preset. Needs a WebGPU-capable browser (recent Chrome/Edge, or Safari Technology Preview) with a GPU. New here?
