This is how to generate point cloud mesh from the rawDepthPixels data, using Openframeworks and KinectCommonBridge

KinectCommonBridge Mesh Generation

		mesh.clear();
		mesh.setMode(OF_PRIMITIVE_POINTS);
		for(int x=0;x<640;x+=2) {
			for(int y=0;y<480;y+=2) {
				int index = x + y * 640;
				short depth =  kinect.getRawDepthPixelsRef().getPixels()[index];
				if(depth > minDistance && depth < maxDistance) {
					Vector4 world = NuiTransformDepthImageToSkeleton(x,y,kinect.getRawDepthPixelsRef().getPixels()[index] << 3,NUI_IMAGE_RESOLUTION_640x480);
					float scale = 500.0f;
					mesh.addVertex(ofVec3f(world.x,world.y,-world.z)*scale);
				}
			}
		}
