Wish List

December 12, 2011 - 9:08am #1

Hi all,

Please use this thread as a place to consolidate feature requests for the QCAR SDK. If there is something missing that is holding back your development efforts, we'd like to know about it! If you're having trouble with an existing feature and would like more sample code to help you get started, we'd like to know about that too.

Looking forward to your input, thanks!

Invalid Image Target file format

July 14, 2021 - 8:31am #1

Sooo long story short, I really want to use some kind of qr code as image target.

After generating and downloading these image targets and uploading them back to the database, the format is invalid. I tried different qr codes and also converting them. But actually nothing really works.

Using other image targets works, but I really want to use qr codes. Anyone some idea what I could do or how to convert them properly to get it to work?

Simultaneous use device database and cloud

June 26, 2021 - 4:12am #1

Hello, how can I simultaneous use device database and cloud? I want my Image Target to use two databases, or maybe I have to create two Image Targets, one for Cloud DB, one for Device DB. How do I do that?

New 10.0 Version

June 22, 2021 - 8:00pm #1


what about the new 10.0 Vuforia Version?

I had to start a very complex AR project, and I can't wait for this new version, in particular because if I buy a 9.8 license I had to pay a 10.0 license again when the new version arrives.

How to buy a Vuforia License

June 22, 2021 - 7:13pm #1



We are interested in buying a Vuforia license. I have attempted to reach your sales department by filling out several forms on your web site, in addition to booking a phone call with one of your sales officer and sending emails about this call, but I could not get any response from you.

I would appreciate it if you could guide me through this process.


Thank you.

Image target identification and tracking in relation to small object...

May 25, 2021 - 6:57am #1

Dear Vuforia community,

I am writing in order to get some advice concerning the use of image target in relation to small object (1,5 inches in length). What I want to achieve is to make image tracking work with a small red object.

When I use white paper with corners as a sticker attached to it, it works well.

But when the object is used itself, Vuforia does not recognize it.

When I am using two connected objects Vuforia is able to recognize, but cannot distinguish between the models (although I am using as red object image as image target)

Adding UE4 (Unreal Engine) Support

April 21, 2021 - 1:11am #1

Hello guys,

I'm working on adding the vuforia engine to the UE4 via a plugin.

It's still a work in progress, but for now, I've managed to integrate the vuforia engine with the image tracking capabilities.

** what's done for now ** :

- the full vuforia lifecycle integration (Initialization, resumed/unpaused, suspended/paused, and app termination) with of course the initialization of the device, camera, data, and trackers.

- rendering the camera video background

- tracking image targets

- and rendering 3d model on the target image.
