This repository contains formulas which are compatible with the Gnofract 4D fractal generator. Many are also compatible with FRACTINT https://www.fractint.org/ and with UltraFractal https://www.ultrafractal.com .
A fractal formula is a simple program which tells a fractal program how to draw a particular kind of fractal. For example,
Mandelbrot {
init:
z=0
c=#pixel
loop:
z=z*z + c
bailout:
|z|<4.0
}
Draws the Mandelbrot set.
The intent of this repository is to provide an easy way for authors of fractal formulas to collaborate on and share formulas.
All formulas in the repository are MIT-licensed except those in the orgform directory. See orgform/README.md for more detail.
