I want to load a 3D object from a URL to a CloudRecoTarget, anyone knows how to do it?
Can you specify your intention more precise? I'm not sure if if get it.
Where is your problem and what kind of technology are you using (App, Server...)?
I guess you want to upload a 3D object, that you are downloading from somewhere of the web, to the Vuforia Cloud Database to create a Vuforia Marker that can be used in Unity for an AR application.
Usually you have a server that handles the communication between the app and the Vuforia API. Your server can simply add a target (your 3d object) to the cloud database and after analysing the target you can download the marker from Vuforia. That's the way I've done it.
Probably you can do this without a server using Unity and C# only. Have a look at the Vuforia API to write you own Vuforia Client in C#. Maybe there is a code snippet somewhere.

As the guys already said in the comments, this is a security measure imposed by CORS.
Btw. here's a shameless plug: I'm the author of the forge-convert-utils library that can be used to convert Forge models into glTF 2.0. With it you could host the glTF assets anywhere you want (and have the server use any CORS headers that are needed), and you can load them into your Unity app using any of the glTF loaders such as glTFast or UnityGLTF.
I'd like the Hololens to take in through the camera and project an image over tracked images and I can't seem to find a concrete way as to how online. I'd like to avoid using Vuforia etc for this.
I'm currently using AR Foundation Tracked Image manager (https://docs.unity3d.com/Packages/com.unity.xr.arfoundation#2.1/manual/tracked-image-manager.html) in order to achieve the same functionality on mobile, however it doesn't seem to work very well on hololens.
Any help would be very appreciated, thanks!
AR Foundation is a Unity tool and 2D Image tracking feature of AR Foundation is not supported on HoloLens platforms for now, you can refer to this link to learn more about feature support per platform:Platform Support
Currently, Microsoft does not provide an official library to support image tracking for Hololens. But that sort of thing is possible with OpenCV, you can implement it yourself, or refer to some third-party libraries.
Besides, if you are using HoloLens2 and making the QR code as a tracking image is an acceptable option in your project, recommand using Microsoft.MixedReality.QR to detect an QR code in the environment and get the coordinate system for the QR code, more information please see: QR code tracking
i have to build an app like this:
https://www.youtube.com/watch?v=vetDCkbQGM4
It should simply detect the cockpit of a car and should show informations. For example "this is air conditioning", "this is switch button for the radio". The targets will be pre defined. Basically the app should detect everything and should show information.
Can I realize this with Vuforia? Which framework is suitable for this task?
I hope you guys can help me.
Cheers!
Since your targets are pre-defined, the simplest solution would be to use aruco markers to get 3D world positions/rotations through your user's camera feed.
See the AR Marker Detector in the Unity Asset Store for an example. Vuforia uses 'VuMarks' that are more intricate versions of this.
If you can't add computer-readable labels to the real world for your project, then you are talking about real-time object recognition. That is a much harder problem and not yet easily solvable in Unity as far as I know. It would require something like Google's Cloud Vision API. There is a Unity Cloud Vision project on GitHub, but I have no idea how well it works or what it's capabilities are.
Yes it is possible, you were first require to google. There are different SDK/Framework and Unity Asset store packages available.
You can use Free Vuforia AR Starter Kit from asset store to up and run your logic. Or You can also use Free AR Toolkit. There are different kind of tut available which can show you how to implement these pacakges.
I want to build a cross-platform mobile app that can identify QR-codes and will render a 3d model on it using AR.
I found that Unity in combination with Vuforia will do the trick on the AR part, but is it possible here to download and use 3D models dynamically?
Thanks
I guess what you're looking for is called AssetBundle be aware that downloading a large model (+texture) at run time can be heavy and will highly depend on the internet connection of the device.
Hope this helps.
I'm already make an augmented reality app that can read images marker, but I wonder if i can make augmented reality without marker in unity.
Can anyone tell me how?
Maybe What you need is SLAM, I think. Simultaneous Localization And Mapping, and is markerless, just recognite and track the environment.
These are 2 videos about slam:

One is from kudan, one is from wikitude. If this feature is what you want. Then I am sure that what you need is SLAM.
You can get more from:
wikitude slam
kudan
And, vuforia is not adviced. In fact, Smart Terrain does recoginate the environment, it still need a marker.
You can use Google ARCore, Vuforia or 8thWall SDKs. All of them have motion tracking or extended tracking. So you do not have to use markers. You can take a look at ARCore HelloAR example:
https://developers.google.com/ar/develop/unity/tutorials/hello-ar-sample
you can using ARUnity. ARUnity is the Unity plugin for ARToolKit. (Well the marker would be some kind of image which is used for tracking. ARToolKit calls it NFT.)
You can download it here:

(Scroll down for the ARUnity download link)
Documentation is available here:

Best is, it is free and open-source :).
