Help! Processing getting stuck at context.update();!

DeadSound12

Hello everyone! I am having a serious and mysterious issue with my kinect project for school. We're using an Kinect for Xbox 360, with Kinect SDK 1.7, and SimpleOpenNI Library 1.96 in Processing.

This program is much like the AR SandBox project done with Kinect, Linux and some kind of version of C, but for our project we are using processing so that we can add more onto the code (for example, have fish swim in the areas that are supposed to be blue).

Here is the most recent code: `

import SimpleOpenNI.*;


SimpleOpenNI context;
float        zoomF =0.5f;
float        rotX = radians(180);  // by default rotate the hole scene 180deg around the x-axis, 
                                   // the data from openni comes upside down
float        rotY = radians(0);
boolean      autoCalib=true;


ArrayList <PVector> darkGreenPoints = new ArrayList <PVector>();
ArrayList  <PVector> greenPoints = new ArrayList <PVector> ();
ArrayList <PVector> yellowPoints = new ArrayList <PVector>();
ArrayList <PVector> brightBluePoints = new ArrayList <PVector>(); 
ArrayList <PVector> bluePoints = new ArrayList <PVector>();
ArrayList <PVector> darkBluePoints = new ArrayList <PVector>();


///variables to modify the depth level colors

int dgreenEnd=837;

     println("Can't init SimpleOpenNI, maybe the camera is not connected!"); 
     exit();
     return;  
  }
  if(context.isInit() == true)

     println("done!");

  // disable mirror
  context.setMirror(false);

  context.enableDepth();

  // enable skeleton generation for all joints

` This code was working beautifully a couple of weeks ago, and I have not made any drastic changes to it in between then, just some clean up. After adding in println() statements, I see that Processing doesn't go farther than context.update(). I get no errors in the code, and when I remove context.update(), the rest of the code is able to run. All I get is a grey screen.

I have been on the ultimate and extremely frustrating goose chase to find a way to fix this problem. The kinect is functional, as proven when plugged into a 360.

Please help me. I don't know what to do anymore.

Sincerely,

The incredibly defeated student

You'll get a better response if you format your code. Here's how:

Thank you. I fixed it. I was wondering how to make that magic work.
