This program is a toy project of mine that generates fractals.
Given an initial path specified in a text file, it will repeat that shape in an animation to generate a fractal, and will continue until it is rendering at least 100,000 line segments.
For example, to specify a right angle whose coordinates are (0, 0), (0, 1), (1, 1) one would create a text file with the following contents:
0 0
0 1
1 1
This will generate the Levy C Curve. More examples of input paths are in the examples folder.
(Note: the rule this algorithm uses to generate fractals doesn't work if the starting point is the same as the end point.)
To run the program, do runhaskell fractals.hs <inputfile>. For example, runhaskell fractals.hs examples/eyes.txt.
This was developed in GHC 7.10.3 using the Gloss graphics package for Haskell. To use Gloss, run cabal install gloss or stack install gloss.
