Multi marker tracking

Postby yuccai » Mon Oct 03, 2016 5:11 am

Hi everyone,

Does anyone know to run a multi marker tracking example ?
I've tried to run https://artoolkit.github.io/jsartoolkit5/examples/multimarker_barcode_threejs.html and on localhost but I can't get the transform matrix. I still have a Nan value in it.

Thanks for your help

Hi Yuccai,

Where are you extracting the matrix from?

So I have the event 'getMultiMarker' which run a callback with a parameter called 'ev'. My transform matrix is ev.data.matrix.
Here is the code :
arController.addEventListener('getMultiMarker', function(ev){
ev.data.matrix //is the transform matrix
}
By the way, the artoolkit.getTransformationMatrix() function is neither working.

I am having some difficulty with this, but for other reasons. :)

May i ask, when you open the window and load the browser's development tools. Is there any output in the console?
