mxNiRealWorld2Pixel.m
% This function mxNiRealWorld2Pixel, takes an array of real-world coordinates (XYZ, mm)
%   and projects them into projected (image) coordinates (xy)
%
% 	xy = mxNiRealWorld2Pixel(KinectHandles, XYZ);
%
% inputs,
%   KinectHandles : Array with pointers to kinect node objects generated by
%           mxNiCreateContext, such as main, image, IR, Depth and User node.
%  XYZ: A Matrix of type double with size [N,3] 
%
% outputs,
%   xy : A Matrix of type double with size [3,N], where the first two row are 
%           the x and y coordinates.
