title: Render dense point cloud using XNA4.0
body: <p>my trying to use XNA4.0 to render a dense point cloud from Kinect. The only way I know is to render each point as a triangle primitive. It works fine for a small set of points however, the maximum number of primitive I can draw from one call is 65535, but I want to draw a dense 640*480 depth image. Any suggestion on how to do this? Thanks!</p>
