Unlimited Fractals

Dive into the Mandelbrot set and 77 other fractals with infinite zoom. Arbitrary precision math on the GPU keeps filaments razor sharp at any depth.

Dive into the Mandelbrot set and keep going, past the point where ordinary numbers give out, down to a scale a trillion trillion trillion times smaller than where you started. The detail never stops because the math never rounds off.

INFINITE ZOOM, IN AND OUT

Scroll or pinch to zoom, drag to pan, and hold anywhere to dive, steering as you fall by moving while you hold. The view center and zoom are kept as exact numbers with as many digits as the depth needs, so filaments stay razor sharp instead of dissolving into blocks. The heavy math runs on the GPU using perturbation theory, the same technique the deep zoom record holders use, so even astronomical depths stay smooth. Zoom back out just as far, from anywhere. There is no bottom and no wall.

SEVENTY SEVEN FRACTALS IN SIX FAMILIES

Escape time: the Mandelbrot and Julia sets, plus the Burning Ship, Tricorn, Buffalo, Celtic, Phoenix, Newton, Nova, Magnet, and Multibrot. Iterated function systems and L-systems: the Barnsley fern, Koch snowflake, Sierpinski triangle, Pythagoras tree, dragon curves, Hilbert and Gosper space filling curves, and Penrose tiling. Strange attractors: Lorenz, Rossler, Aizawa, Thomas, Chua, Clifford, de Jong, Pickover, and the full run of Sprott systems. 3D fractals: the Mandelbulb, Mandelbox, Menger sponge, Kleinian, quaternion Julia, and more, ray marched and free to orbit.

MAKE IT YOURS

Open any Julia set: click a point on the Mandelbrot set and its Julia set opens instantly; step back just as easily. A coloring studio: smooth gradients, crisp distance shading, embossed 3D lighting, stripe and triangle inequality averaging, and binary decomposition, over palettes you can shift, densify, and randomize. Tune the detail: raise the iteration count to pull structure out of the deep, color the interior, and switch on 2x or 3x anti-aliasing for the final frame. Save your spot: bookmark a location by its exact coordinates, paste one in to jump straight there, and share it as plain text. Export a poster: save the current view as a full resolution image.
