Introduction:

The ArelXML Helper provides PHP methods to generate AREL XML. The full class documentation can be found here.

The basic usage of the ARELXML Helper is like this:

// start - providing path to AREL HTML file and Tracking Configuration
ArelXMLHelper::start(NULL,$arelPath,$trackingXML);

// create your AREL objects

// create a 3D model
$oObject = ArelXMLHelper::createGLUEModel3D(
                      "1",       //ID 
                      "http://dev.junaio.com/publisherDownload/tutorial/metaioman.md2", //model Path 
                      "http://dev.junaio.com/publisherDownload/tutorial/metaioman.png", //texture Path
                      array(0,-100,0), //translation
                      array(3,3,3), //scale
                      new ArelRotation(ArelRotation::ROTATION_EULERDEG, array(-90,0,0)), //rotation
                      1 //CoordinateSystemID
                      );

//output the object
ArelXMLHelper::outputObject($oObject);

// create a 3D model from an image
$oObject = ArelXMLHelper::createGLUEModel3DFromImage(
                      "image",
                      WWW_ROOT . "/resources/image.png", 
                      array(0,-70,0), //translation 
                      array(5,5,5), //scale
                      new ArelRotation(ArelRotation::ROTATION_EULERDEG, array(0,0,0)), //rotation
                      2 //CoordinateSystemID)
                      );

//output the object
ArelXMLHelper::outputObject($oObject);

// end the output
ArelXMLHelper::end();

These are the different types of objects you can create:

Object	Method to create
3D model from 3D file (obj,md2,fbx)	ArelXMLHelper::createGLUEModel3D
3D model from image (image-plane)	ArelXMLHelper::createGLUEModel3DFromImage
3D model from movie (movie-plane)	ArelXMLHelper::createGLUEModel3DFromMovie
Location based model from 3D file	ArelXMLHelper::createLocationBasedModel3D
Location based model from image (image-plane)	ArelXMLHelper::createLocationBasedModel3DFromImage
Location based model from movie (movie-plane)	ArelXMLHelper::createLocationBasedModel3DFromMovie
General Location based POI	ArelXMLHelper::createLocationBasedPOI
