You should have seen right away that this display is different in several respects. In the first place, I have dispensed with the real space pendulum representation. We have seen enough of that guy for now. Also I have added a Yaw and Pitch Angle controls in the top border of the display. These controls adjust the viewing angles.

The Pitch Angle control tips the viewed object about an axis parallel to the screen and horizontal, through a range from +90 to - 90 degrees. These pitch angles correspond with looking straight at the top of the object and looking straight at the bottom of the object. The Yaw Angle control rotates the viewed object through a full 360 degrees from - 180 to + 180 degrees. You combine the use of these controls to look at any aspect of the viewed object. A single click on the arrows moves the angle 1 degree. A click on the bar on either side of the slide button moves the angle by 10 degrees. Holding the left mouse button down repeats these movements. By holding the left mouse button down on the scroll bar slide button you may drag it to any position.

There was also a less obvious change in the display. Since you now have the capability of swinging the axes around, you might hide part of the picture behind the display border. To get around that situation, you now have the ability to reposition the plot in the drawing area. To do this, simply hold down the left mouse button with the cursor anywhere in the drawing area and drag the entire picture by moving the cursor.

As you can see sectioning the time axis as we have allows us to mark the spot where the orbit passes through the sectioning (p,v) planes. We indicate this spot with a different color and call it the return point. Please defer temporarily the question as to why one would want to do this. In the case of no losses, each plane is intersected at the same location.
