To select a fractal formula, click the Browse button. This opens a modal browser that shows the formula files and formulas on your computer. Double-click on a formula to select it.

Hold down the Browse button to open a menu with fractal formula presets. See Presets.

Some formulas contain additional help. Click the Help button to open it.

Click the More button to access commands to copy and paste the settings and parameters on the Formula tab, and to reset all parameters to the default values.

• Guessing starts with a low-resolution preview, and then gradually increases the resolution while trying to guess pixels instead of calculating them. This is the fastest option, but also the least accurate. When you are working with animations, use this drawing method for fast animation previews.
• Multi-pass Linear also starts with a low-resolution preview, but it calculates all pixels instead of guessing them.
• One-pass Linear calculates all pixels from top to bottom.

For maximum accuracy, use one of the linear drawing methods.

Some fractal formulas do not work well with periodicity checking, in which case you should turn it off. If odd lines or dots appear on the top of the fractal, this may be the case.

Specifies how many extra digits of precision should be used for calculations. See Arbitrary Precision.
