The Barnsley Fern Fractal is a beautiful fractal based on self-similarity sets; mathematically generated patterns that can be reproducible at any magnification or reduction. It is a good example of an iterated function system (IFS) which is a union of numerous copies of itself, each being transformed by a function. These functions are normally contractive, which means they bring points closer together and make shapes repeatedly and infinitely smaller. The best example of an IFS is the Sierpiński gasket, also called the Sierpiński triangle.
Although in it’s most common form the Barnsley fractal represents the form of a plant, or fern, the fractal is much more complex than that and can be used to create a variety of generative art for various means including graphic design, motion graphics and illustration.
This Barnsley fractal fern plugin for Adobe Photoshop is a powerful implementation of the algorithm that unleashes the fractal’s full potential. Its most impressive feature is user-configurable supersampling for clean, antialiased output. All the fractal’s coefficients are fully adjustable thus providing a virtually unlimited number of possible forms.
The shift feature provides controls for asymmetry while the scale feature modifies sizing.
Barnsley Fern Fractal provides file saving and loading so you can save any fractal you create, as well as random fractal generation.
Finally, the plugin provides sampling multipliers for working with high resolution imagery.
