A periodic shift in Polar Roses for Valentines Day
|| 2/14/2007 || 6:28 am || Comments Off on A periodic shift in Polar Roses for Valentines Day || ||
Last month I thoroughly explored the applications of geometric tessellations using the polar coordinate filter. After doing a bit more research I discovered how similar these “amazing circles” appear to be very similar to the sinusoidal curves of a Polar Rose. They use the equation:
In the original process I used to construct last month’s Polar Roses each interation added one tile to the entire panorama. I believe this represents the a in the equation. And after each iteration, there would be a new pedal added.
Today’s discovery is the realization of how these panoramas are wrapped around a cylinder to produce the pedals when the polar coordinate system is used. I’ve been working in whole numbers only, yet if the tiles are wrapped in a cylindrically fashion using a half shift, there will be a change in the pedal’s layout.
So to create this shift, half of one tile is removed on each end (notice above), and when they connect after being wrapped around a cylinder they still form a perfect tessellation and thus new pedal configuration when the filter is applied.
The result of this polar shift is quite interesting- a 90 degree rotation for each iteration.

Shifted 90 degrees:
I can now apply this periodic shift to each of the geometries to produce a completely new set of Polar Roses. This should be interesting.
Grant Park Quilt

View the Google Map of Grant Park in Chicago.
I think it’s the eruption of Buckingham Fountain from “Married with Children’s” opening sequence that does it for me. While I chose to name it Grant Park, I thought of calling it Millennium Park Quilt, which after looking at Google Map’s current imagery, I beat Google to the next Millennium, or at least to the Park by April of 2005 (my imagery’s acquisition date). Because of this, I am humbled to say I symmetrically remixed Frank Gehry‘s Pritzker Pavilion– in Google’s the current imagery the pavilion is still under construction…check the details…
I would have a second one, but due to a power outage, Grant Park Quilt #2 was offered to the gods of electricity as a humble sacrifice. I spent the day reading. Up next will be a fractal of this park.
