Fract-ol

Fract-ol is a graphic fractal exploration program, supporting deep-zooms.

MacOs support only

General

Fract-ol runs it’s calculations on OpenCL, which allows for a high iteration count renders and smooth deep-zoom experience.

This project makes use of my libcl library, to make it easier to work with OpenCL and a complex_opencl library, which allows to perform arythmetics on complex numbers inside the cl kernel.

Fractals

Mandelbrot Set

Julia sets

Burning Ship set

Buddhabrot set

Coloring models

Iteration-based count

Escape-time potential

Log-potential (smoothstep)

Black and white log-potential (smoothstep)

Normal-map effect

Usage

Place the directory in your root folder and compile it with

make

Run the program with

./fractol *type_of_fractal*

Where *type_of_fractal* can be one of the following:

• Mandelbrot
• Julia
• Burning_ship
• Buddhabrot
• Buddhabrot_precalc

There are 2 types of Buddhabrot fractals available – normal one, and precalculated one. Because Buddhabrot set is a very computationally intensive task, calculating the set can take a while. For this reason, the precalculated version is available. It will read the data from the map “save” file, buddha_map, and display it on the screen.

Apart from all the normal functionale, it is also possible to change the direction of light falling onto the set in the color mode 5.
This mode is available for Mandelbrot and Julia fractals only.
