vcg files are just configuration files for rviz.  rviz visualizes data on a running ROS network.  bag files are simply stored data from a ROS network that can be replayed using rosbag.<div><br></div><div><a href="http://www.ros.org/wiki/rosbag">http://www.ros.org/wiki/rosbag</a></div>

<br>
I got a bag file about the robot tf and the pointcloud information, as well<br>
as a xml file named pr2.urdf. I know rviz is a visual tool for vcg file, may<br>
I use the rviz package to visualize the bag file? If not, is there any other<br>
way to visualize the bag?<br>
I just have the above files as well as some stl models, without any other<br>
source. What should I do? Thank you.<br>
