Take the following quadratic complex function z = z^2 + c. Substitute a point, and repeat it again, and again. The points that do not diverge form a Julia set, a fractal of infinite detail and uniqueness. This piece, 'fibr,' blends the uniqueness of the fractal along new dimensions with curves, twists and turns.

The piece is rendered in WebGL using 3D SDF raymarching, with a new algorithm developed for raymarching cross-sections along parametric functions. Only render at sizes and sample counts that your GPU can handle, especially on lower-end devices.

By default, the image is square in the browser resolution at 30 samples. The resolution and samples can be adjusted using the 'size' and 'samples' tags. For example: ?size=800&samples=15 Press s to save a .png once it is rendered.
