Mandelbulber
About this Project

The Mandelbulb is a three-dimensional analogue of the Mandelbrot set. In reality there are many natural fractal shapes such as clouds, trees, broccoli, and such.

The Mandelbrot set is two-dimensional. When it was discovered, computers weren't very powerful and so it wasn't possible to render three-dimensional fractals. But nowadays the computing power is thousands of times better. It has opened up many new possibilities.


By the end of 2007, a small group of people from Fractal Forums decided to develop algorithms and software for rendering 3D fractals. In the beginning everyone tried to expand the Mandelbrot set to three dimensions. But there were many different approaches and some of the first experiments were incredible. We were hooked. It's easy to understand why.


The rendering of first images took alot of time and was difficult because the first programs didn't have any graphical user interface. Fractals were rendered slice by slice; programs needed gigabytes of memory. After development of Distance Estimation algorithms, rendering became faster with less memory consumption.

New types of 3D formulas were also discovered.



These three-dimensional fractals can be zoomed infinitely, just like two-dimensional fractals. The zoom scale is only limited by calculation precision.

Within the Fractal Forums community, two seperate pieces of rendering software have emerged: Mandelbulber and Mandelbulb3D. Each have their strengths and limitations.

Krzysztof Marczak is the creator of Mandelbulber and he continues to enhance it.
