AR.js Custom-Marker

Basic Code for AR.js Custom Marker

1. Upload the image you want inside the black border here (try to avoid white backgrounds).
2. Download the .patt file and the pdf file
3. Change this code in the aframe-ar.js file

      // honor this.data.preset
			if( _this.data.preset === 'hiro' ){
				arProfile.defaultMarkerParameters.type = 'pattern'
				arProfile.defaultMarkerParameters.patternUrl = THREEx.ArToolkitContext.baseURL+'examples/marker-training/examples/pattern-files/pattern-hiro.patt'
				arProfile.defaultMarkerParameters.markersAreaEnabled = false
			}else if( _this.data.preset === 'kanji' ){
				arProfile.defaultMarkerParameters.type = 'pattern'
				arProfile.defaultMarkerParameters.patternUrl = THREEx.ArToolkitContext.baseURL+'examples/marker-training/examples/pattern-files/pattern-kanji.patt'
				arProfile.defaultMarkerParameters.markersAreaEnabled = false
			}else if( _this.data.preset === 'area' ){
				arProfile.defaultMarkerParameters.type = 'barcode'
				arProfile.defaultMarkerParameters.barcodeValue = 1001	
				arProfile.defaultMarkerParameters.markersAreaEnabled = true
			}else {
				// console.assert( this.data.preset === '', 'illegal preset value '+this.data.preset)
			}	    

to this. You need to add the last else if statment.

      // honor this.data.preset
			if( _this.data.preset === 'hiro' ){
				arProfile.defaultMarkerParameters.type = 'pattern'
				arProfile.defaultMarkerParameters.patternUrl = THREEx.ArToolkitContext.baseURL+'examples/marker-training/examples/pattern-files/pattern-hiro.patt'
				arProfile.defaultMarkerParameters.markersAreaEnabled = false
			}else if( _this.data.preset === 'kanji' ){
				arProfile.defaultMarkerParameters.type = 'pattern'
				arProfile.defaultMarkerParameters.patternUrl = THREEx.ArToolkitContext.baseURL+'examples/marker-training/examples/pattern-files/pattern-kanji.patt'
				arProfile.defaultMarkerParameters.markersAreaEnabled = false
			}else if( _this.data.preset === 'area' ){
				arProfile.defaultMarkerParameters.type = 'barcode'
				arProfile.defaultMarkerParameters.barcodeValue = 1001	
				arProfile.defaultMarkerParameters.markersAreaEnabled = true
			}else if( _this.data.preset === 'custom' ){
				arProfile.defaultMarkerParameters.type = 'pattern'
				arProfile.defaultMarkerParameters.patternUrl = _this.data.patternUrl;
				arProfile.defaultMarkerParameters.markersAreaEnabled = false
			}else {
				// console.assert( this.data.preset === '', 'illegal preset value '+this.data.preset)
			}	    

4. Change the marker reference.

<a-marker-camera preset='custom' url='path/to/the/file.patt'></a-marker-camera>

In this repo you can see the example files from Ar.js modified to accomodate the custom marker.
