Wikitude

Hello 

I want to have multiple Images which I can scan and receive an AR information.

According to older entries here, it should be possible by now with the SDK 7.

Unfortunately I wasn't able to implement it so far. When I add multiple "AR.ClientTracker's" only the last image works. 

The goal is not like in the documentation or the samples on GitHub to scan one wtc-file and receive multiple AR images. 

The goal is to have different wtc-files and each wtc-file will show an AR image.

Here is my code which works so far (except there is no possibility to remove the trail watermark with our license):

var World = {
	loaded: false,

	init: function initFn() {
		this.createOverlays();
	},

	createOverlays: function createOverlaysFn() {
			this.tracker = new AR.ClientTracker("assets/wald.wtc",
	
		{
			onLoaded: this.worldLoaded
		});
 
		var phonegap_text = new AR.ImageResource("assets/HinweisTxt.png");
		var overlayOne = new AR.ImageDrawable(phonegap_text, 0.2, {
			offsetX: -0.015,
			offsetY: -0.25
		});

				var pageOne = new AR.Trackable2DObject(this.tracker, "*", {
			drawables: {
				cam: [samurai_eyes_animate, overlayOne]
			}
		});
	},

	worldLoaded: function worldLoadedFn() {
		var message = " style='text-align: center; font-family:Arial, sans-serif;'";
		document.getElementById('loadingMessage').innerHTML =
			"<div" + message + ">Swipe right or use back button to exit.</div>";

		// Remove Scan target message after 10 sec.
		setTimeout(function() {
			var e = document.getElementById('loadingMessage');
			e.parentElement.removeChild(e);
		}, 10000);
	}
};

World.init();

Thanks a lot for any advise...

Hello Eva

Thanks a lot for pointing this out. That was a sample project from PhoneGap which, according your information, is not up to date anymore.

I was able to implement your 01_ImageTracking_2_DifferentTargets project files in my project but I do have two further questions.

I am curious about the picture in the assets folder as well. When I deleted the surfboard and the helmet in the assets folder, it was still working (the pictures still showed up). Am I right building the wtc file also includes the Augment so there is no need to have them in the assets folder as well?

Anyways, when I upload my image in the TargetManager and add an Augment and download the wtc file and just replace your "magazine.wtc" in the multipletargets.js with the generated wtc file the Augment will not show up. Not sure what I am doing wrong but I just changed the wtc file...

Thank you

Hi Eva

I tried it today a couple more times but it's still not working.

As yesterday the Wikitude example works fine but not with custom augment.

As base I used your ImageTracking_2_DifferentTargets project from GitHub (which works).

- I start the WikitudeStudioManager and upload a custom jpg file (two star rated)

- I add an augmentation which is called imageOne.png (same file, name as in your example and named imageOne.png in the code as well).

- I download the wtc file ("This will generate a WTC-file containing 1 targets for offline recognition"). 

- I rename the wtc file to "magazine.wtc" as in your example and as it is in the code as AR.TargetCollectionResource

- The wtc file and the imageOne.png are both in the assets folder

Basically I just took a custom image as target image and put as augmentation the same file as in your project (imageOne.png) and used the new wtc file. But unfortunately it's not working.

Thanks for your support

Hi Eva

Thanks for your help.

It works so far when I create the Experience JS and use some of my existing code, it works..

I do have a problem with a video in the StudioManager and still the trial watermark but if I can't figure it out I will open up another topic...

Thanks a lot
