Benoit fractal software

In the s, Benoit was able to dive much more deeply into his financial theories by using IBM computer processing software to examine vast quantities of financial data at once and to better visualize this new theory. The use of the software led him to the realization that some geometric forms, called fractals, are rough at all scales. They are effectively patterns nested within each other such as fern leaves in nature.

Like the fluctuations of markets, many naturally occurring phenomena had some level of fractal geometry, including the clustering of galaxies, a rocky coastline, music, blood vessels, and the internal structures of plants. Benoit called this his theory of roughness. He believed that fractals could help to simplify the superficially messy objects in science. The rougher and messier a thing, the larger the degree of fractal geometry it represented. In fact, Benoit believed that fractals were a much more intuitive and common geometric occurrence than traditional Euclidean geometry.

Benoit wrote several books and many papers about fractals, his theory of roughness, and its economic implications. He won the Wolf Prize for physics in , thanks to these very same discoveries. Benoit had a passionate and accessible writing style and supplemented his papers and books with many detailed illustrations. This allowed his work to rise to mainstream prominence and to be read by many non-specialists.

In , he was promoted to the rank of Officer. Today he is remembered as a pioneer and a visionary creative. He used intuition, computer visualizations, and a multidisciplinary sensibility to discover fractal geometry and to realize its numerous applications to the broader universe.

Fittingly, today he has a small asteroid named in his honor. This article is the sixth in our series exploring the lives and achievements of famous mathematicians throughout history. Our last article was about the British mathematician Ada Lovelace!

By Lillie Therieau Benoit Mandelbrot saw the harmony and beauty in the messier parts of the universe, applying his theory of fractal geometry to make sense out of chaos. Our Blog. January 10, January 3, Because complex images can be generated from simple formula fractals are often used among the demoscene.

The generation of fractals by calculation without computer assistance was undertaken by German mathematician Georg Cantor in to create the Cantor set. Some were conceived before the naming of fractals in , for example, the Pythagoras tree by Dutch mathematics teacher Albert E. Bosman in The development of the first fractal generating software originated in Benoit Mandelbrot 's pursuit of a generalized function for a class of shapes known as Julia sets.

In , Mandelbrot discovered that one image of the complex plane could be created by iteration. He and programmers working at IBM generated the first rudimentary fractal printouts.

From the early s to about hundreds of different fractal types were formulated. The generation of fractal images grew in popularity as the distribution of computers with a maths co-processor or floating-point unit in the central processing unit were adopted throughout the s. At this time the rendering of high resolution VGA standard images could take many hours.

Fractal generation algorithms display extreme parallelizability. Fractal-generating software was rewritten to make use of multi-threaded processing. Subsequently, the adoption of graphics processing units in computers has greatly increased the speed of rendering and allowed for real-time changes to parameters that were previously impossible due to render delay.

An early list of fractal-generating software was compiled for the book titled Fractals: The Patterns of Chaos by John Briggs published in There are two major methods of two dimensional fractal generation. One is to apply an iterative process to simple equations by generative recursion.

In fractal software values for a set of points on the complex plane are calculated and then rendered as pixels. This computer-based generation of fractal objects is an endless process. In theory, images can be calculated infinitely but in practice are approximated to a certain level of detail. There are numerous coloring methods that can be applied. One of earliest was the escape time algorithm. Some programs generate geometric self-similar or deterministic fractals such as the Koch curve.

These programs use an initiator followed by a generator that is repeated in a pattern. These simple fractals originate from a technique first proposed in by Koch. The other main method is with Iterated Function Systems consisting of a number of affine transformations. The former method represents the classical stochastic approach while the latter implements a linear fractal model. Three dimensional fractals are generated in a variety of ways including by using quaternion algebra.

The Buddhabrot method was introduced in Programs might use fractal heightmaps to generate terrain. Fractals have been generated on computers using the following methods: Menger sponge , Hypercomplex manifold , Brownian tree , Brownian motion , Decomposition , L-systems , Lyapunov fractals , Newton fractals , Pickover stalks and Strange attractors. Many different features are included in fractal-generating software packages. A corresponding diversity in the images produced is therefore possible.

Most feature some form of algorithm selection, an interactive image zoom , and the ability to save files in JPEG , TIFF, or PNG format, as well as the ability to save parameter files, allowing the user to easily return to previously created images for later modification or exploration.

The formula, parameters, variables and coloring algorithms for fractal images can be exchanged between users of the same program. There is no universally adopted standard fractal file format. One feature of most escape time fractal programs or algebraic-based fractals is a maximum iteration setting.

Increasing the iteration count is required if the image is magnified so that fine detail is not lost. Limiting the maximum iterations is important when a device's processing power is low. Coloring options often allow colors to be randomised. Options for color density are common because some gradients output hugely variable magnitudes resulting in heavy repetitive banding or large areas of the same color.

Because of the convenient ability to add post-processing effects layering and alpha compositing features found in other graphics software have been included. Both 2D and 3D rendering effects such as plasma effect and lighting may be included. Many packages also allow the user to input their own formula, to allow for greater control of the fractals, as well as a choice of color rendering, along with the use of filters and other image manipulation techniques.

Some fractal software packages allow for the creation of movies from a sequence of fractal images. Others display render time and allow some form of color cycling and color palette creation tools.

Standard graphics software such as GIMP contains filters or plug-ins which can be used for fractal generation. Blender contains a fractal or random modifier. Many stand-alone fractal-generating programs can be used in conjunction with other graphics programs such as Photoshop to create more complex images. POV-Ray is a ray tracing program which generates images from a text-based scene description that can generate fractals.

Scripts on 3ds Max and Autodesk Maya can be used. A number of web-based interfaces for the fractal generation are freely available including Turtle Graphics Renderer.

Because of the butterfly effect , generating fractals can be difficult to master. A small change in a single variable can have an unpredictable effect. Some software presents the user with a steep learning curve and an understanding of chaos theory is advantageous. This includes the characteristics of fractal dimension , recursion and self-similarity exhibited by all fractals.

Notable fractal generating programs include:. Most of the above programs make two-dimensional fractals, with a few creating three-dimensional fractal objects, such as mandelbulbs and mandelboxes. Mandelbulber is an experimental, cross platform open-source program that generates three-dimensional fractal images. The open source GnoFract 4D is available.
