TRIGONOMETRY OVERVIEW:
A polar graph represents a math equation where the distance [r] from the center of the graph is determined by an equation. [r=1 is a circle. r=sin(angle) makes loops]
Polar Graph:
http://en.wikipedia.org/wiki/Polar_graph
Normally you start the angle from 0 and go all the way around to 360 degrees incrementing by some small amount. When you skip faster around the circle in a regular interval (say every 80 degrees), you get something interesting. A Maurer Rose http://en.wikipedia.org/wiki/Maurer_rose
Geometrics takes this maurer rose idea and puts you in control of the design:
The amount to skip, and a multiplier for the angle (to determine how many petals your maurer rose will have).
DESCRIPTION OF CONTROLS:
1. Swipe left or right - Restart the pattern changing the number of "flower petals"
2. Swiping up and down - Restart the pattern changing the "amount of skip"
3. Pressing and holding - Cycle through 3 trigonometric math functions (single sin equation, multiple sin equations, and a tan equation)
Previous Versions
Here you can find the changelog of Geometrics since it was posted on our website on 2013-08-23 03:39:08.
The latest version is 11 and it was updated on 2026-06-30 07:02:50. See below the changes in each version.
Geometrics version 11
Updated At: 2017-10-02
Changes: * Fixed the ability to save the spiral graph image to external storage.
* Advertisements were made smaller to allow users to interact better with the pattern generator.
* Can now press the "back" button to have access to advanced spirograph features.
Geometrics version 8
Updated At: 2013-09-05
Changes: * Fixed some image sizing issues.,* Forced the second pattern to start off in an "interesting" place. (Previously, it would produce what looks like just random lines. Probably because the "pattern" is so complex our human brains don't find them "interesting" because we cannot recognize the pattern),* Set radius and radius change manually.,* Press and hold twice to see the tan(THETA) function produce more beautiful patterns.
Geometrics version 8
Updated At: 2012-03-03
Changes: Several fixes and updates
