So I want to place an object on a table and the application is supposed to create a virtual world on the table and then place a virtual object inside that world where the real object is in the real world.

Idea is that I can use the reference object just for the initial position of the virtual object, and then let the virtual object move around without the reference object remaining onscreen (or requiring to still be tracked).

If someone could tell me if Vuforia is the right SDK for that and if so, what would be the rough approach I should take, that would be great. Initially I thought smartscene was what I was looking for, but now I'm not so sure.

Is the Vuforia View app a platform that we can use and upload our content? It looks like a great app, but I am wondering if it is a showcase of Vuforia capabilities for developers to demonstrate AR capabilities to prospective clients.

Hello,

I'm relatively new to Unity and AR project and I'm stuck trying to dynamically add a 3D model to an Image Target. I have the following error and cannot understand where is the problem: error CS0246: The type or namespace name 'ITrackableEventHandler' could not be found (are you missing a using directive or an assembly reference?)

Here it is the code I'm using which's been taken from https://library.vuforia.com/content/vuforia-library/en/articles/Solution/Working-with-Vuforia-and-Unity.html#dynamically-add

using UnityEngine; using Vuforia; using System.Collections; public class MyPrefabInstantiator : MonoBehaviour, ITrackableEventHandler {   private TrackableBehaviour mTrackableBehaviour;   public Transform myModelPrefab;   // Use this for initialization   void Start ()   {     mTrackableBehaviour = GetComponent<TrackableBehaviour>();     if (mTrackableBehaviour) {       mTrackableBehaviour.RegisterTrackableEventHandler(this);     }   }   // Update is called once per frame   void Update ()   {   }   public void OnTrackableStateChanged(     TrackableBehaviour.Status previousStatus,     TrackableBehaviour.Status newStatus)   {     if (newStatus == TrackableBehaviour.Status.DETECTED ||         newStatus == TrackableBehaviour.Status.TRACKED ||         newStatus == TrackableBehaviour.Status.EXTENDED_TRACKED)     {       OnTrackingFound();     }   }   private void OnTrackingFound()   {     if (myModelPrefab != null)     {       Transform myModelTrf = GameObject.Instantiate(myModelPrefab) as Transform;       myModelTrf.parent = mTrackableBehaviour.transform;       myModelTrf.localPosition = new Vector3(0f, 0f, 0f);       myModelTrf.localRotation = Quaternion.identity;       myModelTrf.localScale = new Vector3(0.0005f, 0.0005f, 0.0005f);       myModelTrf.gameObject.active = true;     }   } }

Could anyone help me? Thanks in advance!

Hi  I want to make interactive color Book the artist mange UV map  to wrap the body by marker image and i tried to use region capture but results not good or accurate then i tried open_cv and matching algorithms like SIFT &ORB to get marker region but Homography not accurate and not stable, So any suggestions how to improve workflow OR any new suggestions

I want to get results like this video

Hi, 

I don't understand what kind of unit of measure I had to insert in unity: if I try to add a target of 7.5 cm (0.075 meters) and I insert 7.5 in width, the image has 5 stars as augmentable value. If I insert THE SAME IMAGE but with a width of 0.075, the image has 0 stars ....

But in unity, I have a lot of problems with the 7.5 target, and no problems with 0.075 target (well, the problem is that the quality of tracking is very very bad!)

Any help??

Hello! Can you add the Vuforia SDK for Unity function to an external USB camera (for Android smartphones) and the camera mirroring function (for Device Type in Phone mode+Viewer).

Hello,

https://library.vuforia.com/articles/Training/vuforia-fusion-article.html

Based on this, SLAM is the default if both ARCore/ARKit and VISLAM are not present on the user device.

What functionality of Markerless is offered by SLAM in Vuforia? As I know, from the sample application, only Ground plane is Markerless. All others like Image Targets, Model Targets are Marker based approaches. Are there any other Markerless examples in your Sample? So for instance, if I have a device that does not support both ARCore/ARKit and VISLAM, what addionally can I achieve by SLAM only that is Markerless, that I could not have achieved via the Marker based approach? Is it Extended Tracking? Is Extended tracking required for Marker based approach? I thought Extended tracking makes sense only for Markerless.

Also, it seems that all marker based approaches use FUSION_PROVIDER_VUFORIA_VISION_ONLY type as the provider as seen from the log of Sample apps. Does it mean SLAM is used for Marker based approaches too? What is the provider type for SLAM only? Can you give an example use case. I used to think SLAM is only required for Markerless but maybe I am missing something here.

Thanks.

Hello Everyone,

I am a beginner at using Unity and Vuforia and I am building an app for Android that allows user to pick up a 3D physical object which has a marker on top of it. Once the Marker is detected an AR object replace the 3D physical object. My problem is a very common one in AR which is fingers are obstructed behind the AR object. What I want is to to show the fingers as if are holding the AR object. I have been trying to google this for long time and I only found very few step samples which are quite complicated for a beginner like me. If anyone in the forum can please help me sort out this problem. I need a clear guidance with simple language for me to reapply those steps to my project. Also I Know of Vuforia occlusion management asset but I am not sure if that applied to my problem

Many thanks in advance.
