Ptc Vuforia Engine

[Ceumar Pee]

I'm new to unity and vuforia to complete a project i need vuforia engine AR in package manager, the steps shown in the video for unity are Window->Package Manager -> All Packages ->Vuforia Engine AR.I couldn't access the AllPackages menu so someone suggested that i preview all the packages,i used player setting and selected preview packages, for all the other packages, this doesn't work either.

So i downloaded the vuforia sdk form the site, and i imported all of them into the project,it still didn't show me anything in the GameObject window, i tried to search for the required components like ARCamera and GroundPlaneFinder in the file i imported and they weren't in there.

Nevermind, i figured it out, apparently in versions above 2020 in unity it is labelled as vuforia engine to access it go to window->package manager-> my assets->vuforia engine-> import(these were my settings don't know if it changes from version to version)

Be careful and don't try to import it in middle of a project though apparently it needs to be initialized/imported at the start of the project to avoid dependencies. you can create your project later.

I created a unity project with vuforia engine 10.19.3, exporting and running it on android. The first time the app is started, it requests the missing camera permissions as expected and the engine gets initialized. No matter, if I select "only once" or "when using the app", the next time I start the app, there is no request for camera permissions and the app crashes with a vuforia engine initialization error (see logcat).

If I manually set the camera permissions to none in the android settings for the app, the next time I start the app, permissions get requested again and the engine initializes flawlessly.If I manually change back to other settings then none, app crashes again with the same error.So it only works once after I removed the camera permissions manually.

I have recently purchased the ML2 excited to try the Basic Vuforia Features and after following the ML2 Project Setup + "Getting Started with Vuforia Engine and Magic Leap 2" on the vuforia Developer Library nothing happens when i launch the application. The application simply asks for permission to use the camera and thats it.

After that I imported the unity package of the 3D scan in my project and inserted it to the Area Target Object. I then placed few cubes within the model.
I do see the 3D-model of my room in the unity editor.

I've created a unity project and finished the Magic Leap Project Setup. After that I imported the Vuforia Magic Leap 2 Sample Asset from the Unity Asset Store. After finishing the steps i receive the following errors, which makes it unable to be build.

There seems to be a conflict happening somewhere. I heard from our team that since it looks like you first did the ML2 setup instructions and then imported the sample, that could cause conflicts. Could you try to import the ML2 sample from the asset store in a fresh project and see if that fixes the issue?

i found the solution to the problem in one of the other threads in this forum.
Starting the Vuforia Initialization delayed was the key.
However this fix was from April 2023 so perhaps it should be further investigated.

@darthviper107 Since you moderate here in the forum, i believe that you have some connection with the dev team at Epic. Is there any reason for why Epic does not implement in the main branch the new updates that ARcore has right now? Cause the 4.22 version of the engine is still in the ARcore version 1.2, and the plugin on there part of the branch is in 1.7. Anouther thing, is that it seems they stoped Unreal Engine support, cause the Unity branch is already at the 1.8.

Vuforia Engine is the most widely used platform for AR development, with support for leading phones, tablets, and eyewear. Developers can easily add advanced computer vision functionality to Android, iOS, and UWP apps, to create AR experiences that realistically interact with objects and the environment.

To install this package, follow the instructions in the Package Manager documentation.Alternatively, you can just enable Vuforia Augmented Reality Support through the XR Settings section of the Player Settings (Edit->Project Settings->Player).

After adding the Vuforia Engine package to your project, you can add Vuforia functionality to your scene by adding game objects from the Game Objects -> Vuforia Engine menu.To learn more about Vuforia Engine, go to: -started-with-vuforia-in-unity.html

Vuforia Engine offers a broad range of features and targets to make your AR development process more flexible. One of our newest features, Vuforia Model Targets, is a key capability for both commercial and industrial uses. Model Targets allow applications to recognize physical objects like machines, automobiles, or toys and track them based on a CAD or digital 3D model. For industrial uses, this feature can provide assembly workers and service technicians with AR work instructions and procedural guidance while in the factory or out in the field.

Existing Vuforia Engine apps that were built for phones and tablets can easily be configured in Unity to run on HoloLens. You can even use Vuforia Engine to take your new HoloLens app to Windows 10 tablets such as the Surface Pro and Surface Book.

The best starting point for learning about Vuforia Engine and HoloLens is the Vuforia Engine HoloLens sample (available in the Unity Asset Store). The sample provides a complete HoloLens project including pre-configured scenes that can be deployed to a HoloLens.

The scenes show how to use Vuforia Image Targets to recognize an image and augment it with digital content in a HoloLens experience. The Vuforia Engine HoloLens Sample also includes a scene showing the usage of Model Targets and VuMarks on HoloLens. You can easily substitute your own content in the scenes to experiment with the creation of HoloLens apps that use Vuforia Engine.

Developers looking to create their own AR experiences with Vuforia Engine and HoloLens should sign up on our Vuforia Developer Portal at developer.vuforia.com. In the portal, developers have access to the Vuforia Engine Forums where they can join community discussions, a library with in-depth documentation on all the Vuforia Engine Features, and the Vuforia Target Manager where users can create their own custom Targets. Developers can also sign up for a free Developer License using the Vuforia License Manager.

Device Tracking maintains tracking even when a target is no longer in view. It's automatically enabled for all targets when the Positional Device Tracker is enabled. For HoloLens applications, the Positional Device Tracker is started automatically in Unity.

Targets that are detected, but no longer in view, are reported as EXTENDED_TRACKED. In these cases, the DefaultTrackableEventHandler script that is used on all targets continues to render augmentation content. The developer can control this behavior by implementing a custom trackable event handler script.

It's possible through the Vuforia Engine to manage the performance on the HoloLens to extent AR experiences and reduce the workload on the CPU. The Vuforia Engine offers three modes that can be selected: default, for optimizing speed, and for optimizing quality.

I explored the vuforia SDK for unity while working on unity for one of my AR experience where I had to track the image and got a very good output compared to the image tracking of unity.
But I found out that the surface tracking of vuforia was terrible and had a lot of issues with it.

The most liked part about Vuforia is it uses the existing 3D cad files to generate the Augmented reality experience from it.
The Vuforia Dashboard is quite easy and user friendly.
The Unity SDK of Vuforia works without a hinch for me and is easy for a beginner to start with as there are proper documentation available for it.
It is a modern API that uses 80 % of smaller dataset and provides better output in differernt lightning conditions.
It provides better and improved tracking on a moving objects.

Its surface detection for not much proper and stable as many of the times it doesn't works if the lighting conditions are not proper on surface.
Its still under development phase so there is no proper solution available for thais issues from quite few time.

Vuforia is an augmented reality software development kit (SDK) for mobile devices that enables the creation of augmented reality applications.[1] It uses computer vision technology to recognize and track planar images and 3D objects in real time. This image registration capability enables developers to position and orient virtual objects, such as 3D models and other media, in relation to real world objects when they are viewed through the camera of a mobile device. The virtual object then tracks the position and orientation of the image in real-time so that the viewer's perspective on the object corresponds with the perspective on the target. It thus appears that the virtual object is a part of the real-world scene.

Vuforia provides Application Programming Interfaces (API) in C++, Java, Objective-C++, and the .NET languages through an extension to the Unity game engine.[3] In this way, the SDK supports both native development for iOS, Android, and UWP while it also enables the development of AR applications in Unity that are easily portable to both platforms.
