% This function mxNiDepth, takes the Current-Depth (movie) frame from
% the Kinect-Stream, and makes it available as matlab variable
% D = mxNiDepth(KinectHandles);
% KinectHandles : Array with pointers to kinect node objects generated by
% mxNiCreateContext, such as main, image, IR, Depth and User node.
% D : A 2D Matrix of type Uint16 with Depth information.
% This depth is not in world-coordinates, if you want
% World-coordinates use mxNiDepthRealWorld.
% To go the next movie-frame use mxNiUpdateContext(KinectHandles)
% See also mxNiDepthRealWorld, mxNiCreateContext, mxNiUpdateContext,
