Kepler's (Stellated) Fractals
Hop David attracted my attention to Keplerian Fractals . He replaces every horn of a stellated (non-convex) polyhedron by small self-similar polyhedron. The picture shows that we can make it in two different ways (we will obtain a II-type (solid) fractal if we combine I-type ones). Interactive Kepler's Octahedron is made of 4 Tetra Flakes (hit it to get next iteration). Hop David found out that it turns into a cube under iterations. He found "Cantor's Octahedron" beneath the cube's surface too. Kepler's Stellated Dodecahedron I-type II-type (solid) Kepler's Great Stellated Dodecahedron I-type II-type (solid) .

Now That You're Here
The primary purpose of this site is to exhibit my images and music compositions. In addition, I wish to provide some personal suggestions for creating fractal images and music depending on different levels of technical knowledge. The "thumbnail" Galleries contain a number of fractal images or fractal-derived images created by programs requiring different levels of technical experience. The program used is indicated below each image and "clicking" on the image will link you to an enlarged version. Some enlarged images in Gallery-1 are also accompanied by fractal music compositions. In some instances, fractal images may have undergone additional processing with an image editor (i.e., post-processing) after being generated by the indicated program. The MIDI music for this page was composed with the full MusiNum program discussed below. Media Player (available on Windows Update) is the MIDI player used for Internet Explorer. Crescendo (operating in detached mode) is the MIDI player plugin I am using for . A basic version is available from the Crescendo homepage (freeware).

Fractals and Chaos von Koch Curve Lab Report Neils Fabian Helge von Koch's "Snowflake" Purpose
The purpose of this project is to show how to create a von Koch curve, including a von Koch snowflake. Mathematical Background Swedish mathematician Helge von Koch introduced the "Koch curve" in 1904. Starting with a line segment, recursively replace the line segment as shown below: The single line segment in Step 0, is broken into four equal-length segments in Step 1. This same "rule" is applied an infinite number of times resulting in a figure with an infinite perimeter. Here are the next few steps: If the original line segment had length L, then after the first step each line segment has a length L/3. For the second step, each segment has a length L/3 , and so on. After the first step, the total length is 4L/3. After the second step, the total length is 4 L/3 , and after the k th step, the length is 4 k L/3 k . After each step the length of the curve grows by a factor of 4/3. When repeated an infinite number of times, the perimeter becomes infinite. For a more detailed explanation of the length computation, see [ , p. 107] or

35. Shiki.archive.9512: Fractals
fractals are the opposite of optimal. Intervals, straight lines, planes, smooth surfaces, smooth curves, polyhedra are not fractals.
Wlodzimierz Holsztynski (
Mon, 4 Dec 1995 22:16:50 -0800 (PST)
Alexey's blinding knowledge of fractals:
Before anybody would use the above text for a fractal
metaphor let me correct it, since Alexey's text is absolutely
misleading, extremely.
A fractal has *nothing* to do with covering space optimally.
No fractal covers space. And no fractal surrounds area optimally.
In the plane circles and only circles do but they are not fractals.
In the euclidean space spheres and only spheres (this time with
respect to volume, which is the 3-dim analog of area) do but they are
not fractals. In that sense and in most any natural, naive sense fractals are the opposite of optimal. Intervals, straight lines, planes, smooth surfaces, smooth curves, polyhedra are not fractals. There are two notions of dimension in geometry (in the theory of so called metric spaces): topological dimension and Hausdorff dimension. For regular sets like polyhedra the two coincide with

6. Other Polyhedra
In principle our algorithm should create quantum fractals for each of the regular polyhedra. The only restriction on the array of vectors is that they are all of unit length, and their sum is a zero vector. We added, for comparison with the Platonic solids configurations, two additional simple yet regular figures: double tetrahedron and icosidodecahedron. Notice that tetrahedron is self-dual, while dodecahedron and icosahedron are dual to each other. Double tetrahedron array is obtained by combining with - that is with the inverted configuration. Figure: Quantum Double Tetrahedron. Icosidodecahedron has particularly simple and elegant expression for its 30 vertices: they are of the form: and its cyclic permutations, and and its cyclic permutations, where is the golden ratio. All of its edges are of length . For its 30 vertices was needed to resolve the atrractor's fine structure. Figure: Quantum Icosidodecahedron.

38. Generation Of 3D Fractals For Web
Unlike the well known Lsystems fractals, this algorithm does not need a rather complicated string parser and 3D turtle for its Fractal Trees and polyhedra.
Generation of 3D fractals for Web
A wide variety of amazing 3D fractals can be obtained by iteration of very simple rules many times. The simple rules lead to very small (1-3kb) algorithms and scripts realized in Java, JavaScript or VRML. The scripts are flexible and can be combined in a library of fractals for application in complex scenes. It is well known, that as since fractals possess self-similarity on scaling, therefore they can be made by iterations of scaling transformations. In Figure 1 it is shown how the famous Koch's snowflake is obtained by repetition of simple transformations: scaling, rotations and translations.
Figure 1. Generation of the Koch’s snowflake. The initial segment 1 is shrunk three times, then three small copies are translated upward and two of them rotated by +-60 degrees. Then this procedure is applied again to the entire curve 2 to get the next curve 3 and so on. Unlike the well known L-systems fractals, this algorithm does not need a rather complicated string parser and 3D turtle for its realization. It uses "natural" 3D operations: scaling, rotations and translations and it can be used with any "3D engine" (VRML, Java3D or Java1 applets). Unfortunately, there is no such "built in" 3D engine in present-day browsers.
Fractal Trees and Polyhedra
It turns out that very realistically looking 3D Trees and other Plants can be obtained just as the Koch’s snowflake by repetition of scaling, rotations and translations. Generation of a simple tree is shown below.
