Augmented Reality

Hi All,   I worked this out a little while ago and thought that I should share it with everyone as it can come in handy when trying to work out how to use JavaScript to control widgets.   The issue that I've faced is trying to work out what all different elements that make up a widget are called.  You can see them in the Widget details pane on the right side of the screen when you select one, but it's not really consistent at the back end for naming compared to what I shows in the UI.   There are two ways to see the correct name:   Method 1 - Look in the app.js file   As you create your project, there is an app.js file stored in Projects\<Project_Name>\dist\app.  If you open up this file in an editor, you can search for your widget by name and then if you scroll around, you can see all the twx-widget-property definitions.   As an example, if I look for a 2D image widget that I've put into the experience, I can see the following propert

Hi folks--   I'm working on a couple of applications where it would be useful to be able to extract some information from the video stream on the camera, e.g. OCR. Is there any way to access the camera data in Vuforia Studio? It would be enough to be able to periodically capture a snapshot of the current camera view.   I've tried $scope.app.camera.getPictureData() and $scope.device.camera.getPictureData(), but both of those return reference errors saying "Camera is not defined".   --Clay

I'm changing the 'src' value for 3D Images in my experience and experiencing an issue. Here is the situation:   In Studio the 3D Images do not have Height of Width set, just a scale value. While the experience is running I use JS to change the src of the images via $scope.setWidgetProp()   The initial images set in Studio have correct proportions but then when I change the source (the new image does not have the same HxW dimensions as the original) the new image is forced into the save HxW "box" as the original and is distorted. Is there a way to force the 3D Image widget to update the "auto" proportions after you change source?

can bind multiple events with single property of a model? if yes then how ?

Hello,    Is there a Glossary of terms used in Vuforia Studio? For example, how is a public view defined and how it is different from a registered view.   Thank you!

If I press "next" too quickly, my animations fall out of sync. I want to disable playback until a step finished playing, and then once it finishes playing re-enable play functionality. How can I do that?

"Unable to connect to an Experience Server. Check your settings or contact you Administrator." I am using Vuforia View on a Vuzix M300. I have published the demo app and am trying to run it by scanning the ThingMark, but receive this message. The Vuzix is connected to Wifi, I have set up the Experience Service with the default address in the project and matched it in the View app by scanning the QR Code. When I try to scan the ThingMark in the 'Publishing an AR Experience' help bar on the right side of the screen, I receive this message. I am using a trial of Vuforia Studio. Anyone know how to resolve this issue?

I have created an experience as shown in the screenshot. On click of open button an image should appear and on click of close button the image should disappear. But in vuzix am not able to make out the cursor movement. How to identify the position of cursor once we view an experience in vuzix and try to navigate.       Thanks, Avinash

how to integrate other 3d models like robot arm animated model ? i have other animated 3d model but they are not playing on click button in vuforia studio.

‎07-03-2018 05:17 AM Is it possible to change the width and height  of 3DImage with the javascript code? I tried in every way but in the end it does not change anything.   i used this code.   $scope.add=function() { $scope.setWidgetProp("3DImage-1", "width", parseInt($scope.getWidgetProp("3DImage-1", "width")) + 1);}     or  $scope.add=function() { $scope.view.wdg["3DImage-1"].width += 1}   but not working.     Thnx Giuseppe

Hi,   Is it possible to dynamically add and remove a widget using JavaScript ?  If it is possible could please tell me how to implement that.   Thanks, Desai

Greetings! I have successfully published an experience but am unable to reproduce it on View. If I click Share->Share Experience it has this url . From my understanding that is the url for that particular experience/project. Clicking the ...-> Settings shows the Default Experience Server as https://da1965643490b660.studio-trial.vuforia.io . This, being common to all projects, I believe is the url to the library containing all experiences.   On Vuforia View->Settings->Experience Service I changed the URL to the default experience server url (also tried with the other one). There is no proxy configuration set on settings. After loading for a while it says "We couldn't find any Library Experiences for https://da..."   I have tried reinstalling Vuforia Studio, reinstalling Vuforia View, republishing the project and creating a new account. All yields the same.   Thank you in advance!

Hi, I want to show some data, which is coming from a query.   What do I need to type as the start and end parameters, when the newest data of the last hour (whenever the app is started) should be shown?   Thanks and sorry for this maybe stupid question,   Robin

Hi ,     I want to change the style of the widget dynamically, for ex. i have to change the color of label on button click or any other event of any widget.How can i do that?Regards,Quadir

For some reason "document.getElementById" is only working for me against 3D widgets not 2D widgets. Here is an example: // this works document.getElementById("3DImage-tech8"); //3D image wdg // these do not document.getElementById("button-1"); //button wdg document.getElementById("image-1"); //2D image wdg yes i have confirmed that those ID's do exist in the project. All i get back for the 2D widgets is null, but against 3D widgets i get a nice element array.

Can someone at PTC provide the correct/best method to force a view update?   The scenario is you change a bunch of values (imgsrc, etc...) via JS and sometimes these changes do not update in the view. How can you force a view update?   @ClayHelberg suggested using $scope.$apply() which does seem to do it but will also throw a bunch of "$rootScope:inprog" errors in the console if you call this while something else (twx?) is already calling it.   Possibly this is a not a problem and i should just ignore the errors. I'm just wondering if there is a more polite way to force twx to update? Something like $scope.app.fn.viewUpdate() <-- i made this up

Hi, Is there a way to connect changes in cad to changes within vuforia studio model resource? For example, data changes in cad are tracked and incorporated into creo illustrate(you are alerted changes are made and have the option to accept) is there a similar system to connect pvz files to vuforia or is removing and reuploading the inevitable way of life?   Thanks in advance! -lulu

I have developed a reasonable method for using Google Analytics to track what people are doing in the Experiences I build. For background I'm building experiences for general costumer use, public experiences, so this is some of the only feedback I get.   What you can get out of this Views: How many people are hitting the experience overall. Historical and realtime Device type: Phone vs. tablet. Can help with design direction if you see everyone is using a tablet. Geo data: Where those people are based on IP, country down to city/region/state data if available Event Flow: Rough idea of how people are moving thru the experience. They first do X, then 40% do Y and the other 40% do Z and 20% exit, etc... Area/feature usage: You can see if there are features or area of your experience that few or none are using. Do they not know it's there or just not interested? Setup Studio How this works is using some old Google tech originally designed for tracking email campaigns. Basically

I made a project with a marker and a model on it. But when I look at it in the view the model jumps a bit and doesn't stay steady on the marker like I would expect it.

Hi, there is a 3D file with 14974 parts,based on which I created AR.But the frame per second is always 0.Currently I deleted some most parts and left 1817 parts.Though,sometimes,the frame per second is still below 16,which is unaccetable.Is there any suggestion for this kind of issue?Thanks.

I used Thingworx Studio to create and publish an experience. When I scan the thingmark using the Vuforia View app on my smartphone and tablet, I can view the experience as expected. But when I use the Vuforia View app on the RealWear HMT1 to scan the same thingmark, I get an error message saying no experience found for that thingmark. - I am using the same version of Vuforia View app on my smartphone, tablet, and HMT1. - I am also using the exact same settings i.e. same URL and same thingmark on my smartphone, tablet, and HMT1. - The network connectivity is not an issue either since I am using the same network for all the three devices.   For some reason it works fine on the smartphone and tablet, but it doesn't seem to work on the HMT1 even when I'm using the same URL, thingmark, version, and network on all the three devices.   Any help would be appreciated.   Thanks.

More details about views in thingwork view, more than just numbers?
