Ultra Fractal

Ultra Fractal is a fractal generation and rendering software application. The program works using a similar paradigm to Photoshop, allowing multiple layers to be combined using layer blending modes, transformations and custom fractal formulas. Fractal formulas, coloring algorithms and transformations may be written by users and a large number of such formula files are available in a public formula database. Fractals may be copied from the interface and pasted as plain text into an email, there is a busy mailing list on which many users post their parameter sets. Calculation using arbitrary precision arithmetic is supported, allowing users to zoom to a magnification of 104000. The GUI is customizable with a dockable MDI. The software calculates statistics about the fractal that is being previewed. Other features include fullscreen mode, color cycling, a render queue, distributed rendering calculations and a detailed help file. Version 4 added support for animations and improved flame fractal rendering. UltraFractal is commercial software, but an evaluation version is freely available. The unregistered version creates watermarked renders. The Fractint formulae were converted to an UltraFractal formula file.
