Terminal Point

On occasion you may want to make use of the very last point of an iterated point object. You may want to attach a construction to this point, or you may want to measure some quantity that depends on the point.

You cannot construct a terminal point on an iteration that uses multiple iteration maps.

To construct the terminal point of an iterated point image, select the iterated image of the point. From the Transform menu, choose Terminal Point. The terminal point of the iterated point image is constructed. If the depth of the iteration changes, the terminal point moves accordingly.

When you select an iterated point image, the Iterate command changes to Terminal Point.

In the example above, an iteration was used to construct the flight path of a thrown ball. (The pre-image points, not shown here, defined the initial velocity of the ball and the strength of gravity.) To determine the height of the ball after some number of iterations, the terminal point was constructed and used to measure the distance between the terminal point and the ground.
