- Fraxious
-
- Fraxious is a program which displays Mandelbrot, Julia, and a few other
- fractal types. Currently, it runs only on PowerMac.
-
- Overview
- You create a fractal by choosing New and the fractal type you want from the
- File menu. You are then presented with a dialog box of parameters to fill
- in. When you press OK, Fraxious creates a window and generates the fractal
- in it. You can adjust the colours using the Palette floating window.
- You can 'zoom in' by selecting a portion of the currently displayed fractal.
- Saving the fractal saves it as a PICT with some other resources, so you can
- reopen it in Fraxious to continue generating or adjust the colours, or open
- it in an image-editing program like Photoshop.
- When you have two fractals of the same type open, you can create a movie
- which 'moves between' the two fractals. For example, you could create a
- movie between a Mandelbrot and a zoom of it; between two Julia Sets with
- different real and imaginary parts; or between two Mandelbrot sets using
- different powers of Z.

- Fractal Types
- Mandelbrot - mandelbrot set for Z^2 + c
- Julia - Julia set for Z^2 + c
- Newton - Newtons method for Z^n - 1
- Henon Map
- Strange Attractor
- FM2D - Two-dimensional fractal brownian motion - good for clouds
- General Mandelbrot - Mandelbrot with (fairly) arbitrary equations. Allows
- expression with */+-^ operators and functions real, imag, abs, norm, arg,
- conj, cos, cosh, exp, log, sin, sinh, sqrt, sin, sinh, sqrt, sqr, tan, and
- constants e and π (pi). For example: (Z/e)^c+sin(c) or ((c+e)^(z*c)). Be
- warned - this is slow, as the equation is interpreted rather than compiled.
- General Julia
- Lyapunov
-
- Bugs.
- There are some bugs which cause the program to end unexpectedly. Please let
- me know of any bugs you find, with details of how to recreate them.
-
- Comments.
- Please let me know of any improvements or any interesting algorithms to add.
- Also let me know if you have found the program of any use.
-
- This is freeware.
