JSARToolkit-Wrapper

A simple API to make JSARToolkit easier to use.

Example Usage:

    // Example of creating a new tracker object with all possible options

    var myTracker = jsartoolkit.tracker({

        src       : 'my-video.webm',                  // Source of the video file

        autoplay  : true,                             // Does the video start automatically

        repeat    : true,                             // Loop the video

        volume    : 0,                                // Volume of audio from video source

        target    : doc.getElementById('DOMTarget'),  // The DOM element in which to append the canvas

        width     : 720,                              // Width of the final output

        height    : 360,                              // Height of the final output

        threshold : 100,                              // Adjust tracking-threshold to suit video lighting

        ratio     : 0.5,                              // Adjust size of hidden tracking-canvas (1 = same as video size)

        debug     : false                             // Add a debug canvas to the DOM target that will help when adjusting the threshold

    });

    // Add an image to the first Augmented Reality marker

    myTracker.marker(0).image('my-image_01.png');

    // Add Blender3D models to Augmented Reality markers

    myTracker.marker(2).model('HTML5_Logo001');

    // Adjust properties of Marker_0

    myTracker.marker(0)

      .scale(1)

      .axis(0, 0, 1)

      .angle(0)

      .position(0,0,0)

    ;

    

    // A callback can be fired when an image has been loaded

    myTracker.marker(1).image('my-image_02.png', function( e ){

      console.log( 'Image loaded!', e );

    });

    // Add new images for two more Markers

    myTracker.marker(2).image('my-image_03.png');

    myTracker.marker(3).image('my-image_04.png');

    // Update the image for Marker_0

    myTracker.marker(0).image('my-image_04.png');

    // Animate the properties of Marker_0 on a timer

    var interval = global.setInterval( function(){

      var date    = + new Date(),

          scl     = 1.5 + (Math.sin( date/200 ) * 0.5),

          axs     = Math.cos( date/300 ),

          posX    = Math.sin( date/300 ),

          posY    = Math.cos( date/300 )

      ;

    

      myTracker.marker(0)

        .scale(scl)

        .axis(0, axs, 0)

        .position(posY, posX, 0)

        .angle(date / 230)

      ;

    }, 20);

    // Access the Tracker's Video Element and update it's currentTime

    myTracker.video.currentTime = 1;

  };

 

  // Call the initialize function when the page finishes loading

  doc.addEventListener( 'DOMContentLoaded', function(){ initialize();
