[Basic]opencv processing + simpleopenNI

Hi forum, I am trying to use the new openCV for processing library.. Seems great! But all examples uses testImages.. I want to use simple OpenNI (kinect) with this library.. Can some help me with this?

A basic example in simpleOPENNI looks like:

SimpleOpenNI context;
void setup()
{
size(640*2, 480);
context = new SimpleOpenNI(this);
context.enableDepth();
}
void draw()
{
// update the cam
context.update();
image(context.depthImage(), 0, 0);
}
