Hi abhishekkeshri1111,

could you post your question in a dedicated Thread ?

(the current thread is about dragging object in 3D, I fail to see how it relates to your question about Cloud Reco).

thank you

I am sending you the link    "https://github.com/abhishekkeshri/vuforia-project/blob/master/src/com/qualcomm/QCARSamples/CloudRecognition/CloudReco.java"   which i have created for my sample aaps for cloud recognition...

" https://github.com/abhishekkeshri/vuforia-project/blob/master/jni/CloudReco.h "

but i am not able to connect mydatabase to vuforia database. i have uploaded my images but it is not recognising. while i have passed my access key also.

plz tell me the solution.

Hi, we have a simple tutorial for Unity:

https://developer.vuforia.com/resources/dev-guide/unity-drag-ar-object-screen-your-finger

If you are programming natively on Android and/or iOS, an example that could help you is the Dominoes sample; although it does not show how to drag an object, however it shows how to throw a ray from the screen (where you touch with your finger) to a 3D point on the target surface;

this is usually a good starting point for implementing drag and drop of objects via touch interface, so I reommend you take a look at that sample and build on top of it (in particular, you can reuse all the math utility functions that you find there).

I hope this helps.

Hi thank you , your solution was helpful , now i would like to work on dragging and dropping objects......is there any sample app which has that feature?? i checked out the api but having an example would be better..

Hi, the best I can recommend is to read the ImageTargets sample, while consulting the Dev Guide and the API reference which will help you understand the meaning of the various classes and functions used in the sample:

also, are you interested in developing the App for Android, iOS or Unity ?
