cmunistrokegesturerecognizer's Issues

Recognize Circle with Center & Radius/Diameter

I'm using your project to detect if user draws a circle. The detection is fine. However, I'd like to know if it's a circle detected, then what is it's center and radius.

Can you help me with this?

Make it Multi Stroke Gesture Recognizer

Hi,
Thanks for the great code! Anyway, do you think how hard it'll be to make this code recognize multi-stroke?

I am thinking of recognizing the first stroke, filter the 3 templates with highest percentage and wait for the second and....

Any suggestion is much appreciated!

straight lines recognition

It fails to recognise straight lines. unistrokeRecognizerPathDistance uses GLKVector2Distance and GLKVector2Distance can return nan. I guess you should check for that

Crash : while creating new template

I found the following crash while adding a new template.
I am using IOS 5.0 simulator.
