QUOTES

“..The patterns and colors this thing makes are amazing. Swipe your finger on the screen and change the shapes and colors. A nice simple app that’s fun to watch.”

“Much like a watered-down version of a 20-year old Windows app called Kaleidescope that was quite cool in its day. …”

“Very pretty designs. I got it to entertain my little grandson, and he likes to watch it, and touch on the designs to change them. …”

“I will play a Pandora lullaby and turn the Geometrics app on for quiet time and my grandson who is 11months will quietly watch it :)”

“it is a nice app to watch and entertain my grandchildren with for a short period of time, they have asked me to get them a real Spirograph for Christmas.”

“This app is very cool to watch. This is one of the first apps I ever bought & still look at it every day.”

– Easy controls.
– Beautiful designs
– The Other apps in the app store that are similar (kaleidoscope, Spin Art, Fireworks, Spirograph, Tripping App, Mandala Generator) have nice patterns, but were made ahead of time by the developer or an artist using the same math as Geometrics. With Geometrics, you are the creator, discoverer, artist, and mathematician.
– Advanced users can set the equation properties manually.
– Images can be saved to your device.

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)
