Connect new markers to different models

April 9, 2013 - 5:53am #1

Hello. I am new with Vuforia and I am trying to add new markers to the ImageTargets example to be able to recognize them and show the model I want. I've studying the code but I don't find any clue.

Thank you very much

OK. I will look for a solution. 

Thank you very much

Vuforia needs an ImageTarget (or alternatively a FrameMarker) to determine the position of the "virtual world" (which includes your 3D model) with respect to the Camera.

If you don't want to use a target, then you need to figure out your own solution, for instance using the Gyro sensors of your device (and perhaps use Vuforia just fro rendering the Videobackground), but this is not a case explicitly supported by Vuforia.

I did it thanks to the articles you showed me. Thank very much. I will continue learning vuforia! Only one more thing: Is it possible to place a 3D model in a specific position around the user using Vuforia without targets (for example 3 meters west)?? 

Thank you very much

Thank you very much for your help. I'm going to study the code and articles and I'll tell you later.

Thanks!

Hi,

for adding new targets, you will need to create your own DataSet (also know as "Device database") by uploading a few images to the Target Manager, and then load your dataset at runtime, using the QCAR::DataSet::load() function, as shown in the sample code in the ImageTargets.cpp file (see the  loadTrackerData() function)

More in general, I would suggest to read this article about Image Targets:

https://developer.vuforia.com/resources/dev-guide/image-targets

This article is also another useful introduction to the topic above:

About how to render your own 3D  model, you can look at this step-by-step tutorial:
