Standard classes

All standard transformations, fractal formulas and coloring algorithms that come with Ultra Fractal are also available as classes in the Standard.ulb file. This file is installed with the other standard formula files in the main formula folder. For more information, see the documentation for the standard formulas:

• Standard transformations
• Standard fractal formulas
• Standard coloring algorithms

For tips on how to use the standard classes, see the class usage examples.

Generally, to get as much formulas and classes working together as possible, it is necessary for them to share the definition for common types of classes. These shared definitions are in the file common.ulb. By adhering to these definitions, different formulas and classes from different formula authors can easily work with each other. The common.ulb file is installed in the folder for public formulas so it can be updated automatically via the online formula database when necessary.

The common.ulb file is intended mainly for formula authors. For everyday users, it does contain some useful classes:

• Clip Shape Merge allows a single clip shape parameter to accept multiple clip shapes. See Generic Clipping.
• Image Trap allows an image to be used as a color trap for the Direct Orbit Traps coloring class.
• Transform Merge allows a single transformation parameter to accept multiple transformations. See Generic Transformation.
• Trap Shape Block and Trap Shape Merge allows a single trap shape parameter to accept multiple trap shapes, and to transform trap shapes. See also Example 2 - Orbit trap classes.

For formula authors, the common.ulb file is invaluable and almost any class should be based on one of the base classes found here. If you think modifications or new base classes are needed, please contact info@ultrafractal.com with your suggestion.
