Gnofract 4D – create beautiful images called fractals

Gnofract 4D is a GNOME-based, free, open source program which allows users to create beautiful images called fractals.

The images are automatically created by the computer based on mathematical principles. These include the Mandelbrot and Julia sets and many more.

It allows you to treat a fractal which has more than one parameter as a four-dimensional object and interactively view slices of this object from arbitrary angles, giving rise to some very unusual images.

It contains a Fractint-compatible formula compiler, allowing it to draw an unlimited number of fractal types, using numerous coloring options.

Features include:

  • Easy to user interface.
  • High quality output with 24-bit color rendering.
  • Coloring methods for smooth gradients.
  • Antialiasing.
  • Unlimited undo.
  • Unlimited output size.
  • Full-screen mode.
  • Previews.
  • Simple interaction.
  • Fast calculations.
  • Supports Fractint and UltraFractal formulas and coloring algorithms, allowing it to draw an unlimited number of fractal types, using numerous coloring options.
  • Base fractal can be displayed in millions of ways, using many coloring algorithms, including old favorites like biomorph, powerful options like Orbit Traps, and unique methods like Hot and Cold. Display multiple fixed points, critical values, or other regions using the “fate” option.
  • Create images which are a cross between the two sets and explore their inter-relationships (‘4D’).
  • Explorer Mode and AutoZoom help you find interesting parts of the fractal automatically.
