Point-Cloud of Body with the Kinect SDK

I am making a program with an SDK where, when users are discovered, the program draws a skeleton for them. I recently saw a game advertised on my Xbox, Nike + Kinect, and saw how it displays a copy of a character doing something else:

Or

Can I create a point cloud representation of only the detected person (and not the background)? Thanks in advance!

EDIT

Using this site , I can create point clouds, but still I can’t cut off the human body.

//get player and depth at pixel

int depth = rawDepthData[depthIndex] >> DepthImageFrame.PlayerIndexBitmaskWidth;

//check each pixel for player, if player is blue intensity.

Kinect for Windows SDK v1.5 has a sample that could be changed for this.

Examples of names: depth-d3d or depthwithcolor-d3d.

They are both point clouds.
