Hi everybody.

I'm a beginner with FLARToolKit and I've read many tutorials to learn
how to use FLARToolKit.
I've found a lot about multiple marker, or multiple object, and many
things, but I can't find anything about how to use FLARToolKit without
pattern, like eyetoy video games on playstation.

Zugara use it to create an app for online shopping:
http://weareorganizedchaos.com/index.php/2009/06/23/zugara-launches-online-shopping-app-utilizing-augmented-reality-and-motion-capture/

I've tried to do it, I've found different ideas, but I don't know what
is possible :
- capture a part of the webcam video and use it like it was a pattern,
but functions used to do that need a real pattern (.pat)
- capture a part of webcam video and make a real pattern file using
source code of the application to make pattern file...
- Maybe FLARToolKit is not use to do that?

Thanks for reading

flartoolkit needs one or more patterns, you cant do anything but
recognizing these patterns 3d locations with flartoolkit.

their "buttons" are (or rather may be) actually very simple codes that
simply detect if there is a motion in certain area. some examples of
this are very old (from flash 8 days - long before flartoolkit
appeared), you can find them all over the internet, for example

functions actually need bytearray. look up tarotaro online marker
generator, rip out relevant code and you are set.

that's what it does, doesnt it?

Thanks for your answer.
Know I'm sure that it's not possible with FLARToolKit, I'm going to
use the example you gave me.
It will be easier to do that with BitmapData.threshold than trying to
find not native solutions with FLARToolKit.
Thanks again.

Hi Fabien,

I release my own stuff under OneZeroThrice, but from 9 to 5, I'm
Zugara's Senior Software Engineer. :) I wrote ZugMo, the motion
detection engine that you're asking about.

I can't give up any of the inner workings of ZugMo, because of my Non-
Disclosure Agreement with Zugara, but I can say that, to an extent,
Makc is right. There are some optimizations that allow ZugMo to work
alongside ARtisan and FLARToolkit without loss of frame rate. Work in
the direction he provided and you might find a solution.

Thank you very much.
I'm going to try to do something with ARtisan and FLARTollkit.
Thanks again
