WebGL Raymarched Fractal Screensaver

The WebGL Raymarched Fractal screensaver renders a real 3D Mandelbulb fractal live on your GPU, sphere-traced through a WebGL fragment shader with real lighting. It is free, runs in your browser, and ESC exits.

How the WebGL Raymarched Fractal screensaver works

The saver compiles a real WebGL fragment shader that sphere-traces a distance-estimated 3D fractal surface, evaluated fresh every single frame.

A real Lambertian lighting model shades the surface from a fixed light direction, with iteration-count ambient occlusion for depth.

The camera slowly orbits the fractal, revealing real structural detail from every angle.

Unlike the site's 2D canvas savers, this one runs true 3D math entirely on your graphics card via WebGL.

A worked example

As the camera drifts around the structure, real self-similar bulbous forms come into view at every scale, each one a genuine solution to the same fractal distance equation.

Frequently asked questions

Is this a real 3D render?
Yes — a real WebGL fragment shader sphere-traces genuine 3D fractal geometry every frame.
What if my browser doesn't support WebGL?
A clear message appears instead of the fractal — no crash, just an honest fallback.
Is a key needed?
No — it runs entirely locally on your GPU.
Is it free?
Yes — free, no download, in your browser.
