The yellow wireframe is actually a 3D model, see jni/Cube.h. It is a unit cube that is scaled to match the box size.

See this thread for some help rendering a plane, there's a post containing vertex data a few down:

Try rendering a single plane first. Then you'll need to use rotations, translations, and scales to create a box from six planes.

Thanks Kim ,
if i choose to separate the object into 6 panels, any idea where to begin?

i thought that since i can see a yellow frame that marks the cube i can use this to position my panels.
any idea where is the code for this frame ?

thanks,
Ariel.

Sure, this should be relatively easy. You can model a 3D box with the same dimensions as the physical prop, and use a single texture that wraps all sides. Or, you could render 6 planes sized and positioned just right, each with its own texture. You're still just rendering a 3D object over the camera image.
