The fractal formula creates the basic shape and form of a fractal. Ultra Fractal comes with a number of standard formulas that you can use. You can also download additional formulas from the Internet and even write your own formulas.

Fractal formulas are managed in the Formula tab of the Layer Properties tool window.

- At the top, the
**title**of the fractal formula is shown. Hold the mouse cursor over the title to see the entry identifier and the file name of the formula. - The
**Browse**button opens a modal browser to select another fractal formula. - The
**Reload**button reloads the fractal formula from disk and recalculates the layer. - The
**Edit**button opens the fractal formula in the formula editor. - The
**Help**button opens the help file for the formula, if one exists. - The
**More**button shows a menu with additional commands. - The
**calculation settings**specify how the fractal should be calculated. See Working with fractal formulas. - The
**iteration settings**specify how many iterations should be used. See Maximum iterations. - The
**formula parameters**are additional parameters specific to the selected fractal formula. See Formula parameters.
