Gnofract 4D: For when 2D fractals just aren't weird enough

# Settings Menu

You can set all the fractal's parameters from here.

## Preferences Dialog

### Function Section

Allows you to chose which fractal type to draw. See the section called Fractal Types for details of the types available.

### Parameters

Some fractal types (such as the Quadratic fractal) have additional parameters which you can set. These are displayed here. What parameters there are depends on the fractal type.

### Rendering Section

This has various options to trade off image quality against rendering time. Antialiasing makes the image smoother and nice looking, but takes a lot longer to draw (up to five times longer). Default antialiasing is quite a lot faster than Best mode, but can miss some small details. Max Iterations sets the number of iterations a point will go through before we give up and assume it's a member of the Julibrot. If Auto Deepening is on, the maximum number of iterations is set automatically by Gnofract 4D but you can change it by hand whenever you like. Continuous Potential gives a much smoother image, by basing the color not only on how many iterations the point took to escape, but on how far away from the origin it ended up on its last iteration.

### Bailout Section

The Bailout Function is used to decide whether a point has left the set. If function(z) is greater than the Distance, the point has left the set. A few functions don't work very well with some fractal types, for example Barnsley fractals don't mix well with the Or bailout function.

### Other Sections

Width and Height should set the size of the image in pixels, but for annoying reasons can only increase the size of the image, not shrink it. The Location entryboxes allow you to change the coordinates of the screen center and the image size. The Angles tab allows you to set the rotation angles. Only values between 0 and 2 * pi are different; values outside this range "wrap" to points inside that range.

## Color Browser

The Color Browser is designed to let you quickly choose a color scheme which suits the current fractal, by generating a set of previews to choose between. To update the previews to match the current fractal, click Refresh. To apply a colormap to the main image, click the map.
