NextFractal is an application for creating fractals and other algorithmically generated artwork from scripts.
Rather than exposing only a collection of fixed formulas, the program uses scripting languages to describe the image to be produced. This makes it useful both for interactive fractal exploration and for repeatable, programmable rendering.
Two different grammars are supported. The Mandelbrot language focuses on Mandelbrot, Julia and Fatou sets, while CFDG is a context-free grammar aimed at recursively constructed geometric images.
This is free and open source software.
Key Features
- Creates fractals and other algorithmically generated images from scripts.
- Provides a Mandelbrot domain-specific language for Mandelbrot, Julia and Fatou sets.
- Supports CFDG scripts for generating recursive geometric artwork.
- Includes tools for interactively exploring rendered fractals.
- Lets users alter script parameters to generate variations without rewriting the complete design.
- Provides a real-time graphics engine for displaying the results of scripts.
- Supports time-based animation for parameters that evolve continuously.
- Offers event-based animation for more structured sequences.
- Exports rendered images for use outside the application.
- Can export generated animations as video.
- Includes documentation and scripting examples for learning the supported grammars.
- Uses JavaFX for its graphical interface.
- Uses FFmpeg for video-related functionality and FreeImage for image processing.
- Runs on Linux as well as other major desktop platforms.
