Mathematicians and artists continue to create stunning works in all media and to explore the visualization of mathematics--origami, computer-generated landscapes, tessellations, fractals, anamorphic art, and more
 

Mathscapes, Complex Flows & More :: Anne M. Burns

Computers make it possible for me to "see" the beauty of mathematics. The artworks in the gallery were created using a variety of mathematical formulas.

Tile 7

Here is a fractal tiles created with Geometer's Sketchpad. I start with a single "tile" designed using Geometer's Sketchpad. Then, using Flash Actionscript I place that "tile" in the center of the screen and surround it with 12 copies of the tile that are half the size of the original, then surround those with 36 "tiles" half the size of the second set of "tiles"; the process is continued until the tiles are too small to see. Thus we obtain a "fractal" tiling.

Persian rug

An applet uses a recursive (repeatedly applied) procedure to make designs that resemble Persian rugs. You may choose 3 parameters $a, b$ and $c$, and one of 6 color palettes each consisting of 16 colors numbered 0 through 15. The parameter $c$ ( 0 through 15) represents an initial color. A 257 by 257 square is drawn in the color numbered $c$. Label the 4 corner colors $c1, c2, c3$ and $c4$ (at the initial stage they will all be $c$). then a new color is determined by the formula $a + (c1+c2+c3+c4)/b \mod 16$ and a horizontal and vertical line that divide the original square into 4 new squares are drawn in the new color. The procedure is repeated recursively until all the pixels are filled in.

All of the Circle Pictures are made by iterating systems of Möbius Transformations.

Circle D

Interpreting a complex valued function as a vector field over its domain provides a wealth of opportunities for producing visually appealing images. Starting with a plot of the vector field over a rectangular grid and assigning colors as functions of length and/or direction we easily discern the multiplicities of the zeros and poles of the function. Plotting the vector field of the function only along certain paths, inventing functions for assigning length and color to each vector produces some beautiful images.

The "Mathscapes" artworks in this gallery were created using a variety of mathematical formulas. The clouds and plant life are generated using fractal methods. The mountains are created using trigonometric sums with randomly generated coefficients; then, using 3-D transformation, they are projected onto the computer screen. Value and color are functions of the dot product of the normal to the surface with a specified light vector.

Lilacs

"Inflorescence" is the arrangement of flowers, or the mode of flowering, on a plant--sometimes simple and easily distinguishable, sometimes very complex. "Lilacs" is an example of an imaginary inflorescence that I have created using computer graphics techniques. Two Java applets allow users to see and draw purely imaginary inflorescences at various stages using the recursive (repeatedly applied) functions.
