Fractal Carpet, OpenSCAD, math and more...

During our week 2 class, we worked on creating a carpet fractal in OpenSCAD, which I named "Bombers" (based on the resemblance to a stealth bomber) I created this by modifying some set code in OpenSCAD. The original design was a 100mm square with minimal depth, missing 1/16 of its area. My assignment was to subtract additional area and repeat the design multiple times. Original shape, code featured on the left with directions. Dr. Schreck and I worked on computing the area of the shape, trying to determine the area of the fractal at its first, second and third iterations. I then recreated the shape in OpenSCAD by adding two "/" marks before the location in the code, indicating to the program to subtract that area. My resulting n=1 looked like the following. n=1 n=2 n=3 n=4 n=4 detail In class, we continued to work on the math involved in the fractal, and produced the following calculation of the geometric series needed to continu...

Dutch Blitz Fractal, Tinkercad

My assignment for week 2 was to investigate the online program Tinkercad, and build a fractal shape. I first used Adobe Illustrator to brainstorm a shape, that I call "Dutch Blitz" inspired by the Amish "hex signs" I grew up seeing in Northwest Ohio. These designs are painted and hung on barns for good luck, and often have geometric, quilt-like designs. Hex Signs "Dutch Blitz Fractal" I began with a cube framework, with a second cube turned 45 degrees, and two spoked half-frames jutting out horizontally from the design. I then shrink that same design and rotate it 90 degrees, placing it inside the other, repeating indefinitely. As the design shrinks two-dimensionally, it also shrinks three-dimensionally, pulling in toward the center of the cube. This is seen in the three dimensional models I created in Tinkercad.
