Putting it together – Vuforia^TM with JME

In this section we will show you how to integrate Vuforia^TM with JME. We will use a natural feature-tracking target for this purpose. So open the VuforiaJME project in your Eclipse to start. As you can already observe, there are two main changes compared to our previous projects:

• The camera preview class is gone

• There is a new directory in the project root named jni

The first change is due to the way Vuforia^TM manages the camera. Vuforia^TM uses its own camera handle and camera preview integrated in the library. Therefore, we'll need to query the video image through the Vuforia^TM library to display it on our scene graph (using the same principle as seen in Chapter 2, Viewing the World).

The jni folder contains C++ source code, which is required for Vuforia^TM. To integrate Vuforia^TM with JME, we need to interoperate Vuforia's low-level part (C++) with the high-level part (Java). It means we will need to compile C++ and Java code and transfer data between...
