Now we $("div.version." To view the tree: Here we can see the three frames that are broadcast by tf: the world, turtle1, and turtle2. Now let's look at how tf is being used to create this demo. This demo is using the tf library to create three coordinate frames: a world frame, a turtle1 frame, and a turtle2 frame. Here a tf listener is listening to the frames that are being broadcast over ROS and drawing a tree of how the frames are connected. Keywords: transforms, coordinate frames Tutorial Level: BEGINNER Next Tutorial: Writing a tf broadcaster For debugging purposes, view_frames also reports some diagnostic information about when the oldest and most recent frame transforms were received and how fast the tf frame is published to tf. The values for r, g and b, between 0 and 255, will set the color of the pen turtle1 draws with, and width sets the thickness of the line..
