For using openni package and also for generating point cloud you should have Kinect or Asus Xtion ( Depth Sensor). OpenNI wont work with normal usb camera. usb_cam package is to capture rgb image using usb camera.
For generating pointcloud u can use either Kinect with freenect package or rgbdslam ( available for electric Older version of ROS)

If you are only interested in creating 3D, you can use lsd_slam or ORB slam, it will give nice 3d in real time but it wont publish any pointcloud message.
