EZ Math Movie, Tutorials, Designs, Random Points and Lines

Draw a point and a line segment; repeat.

Here is a simple program that sets up the graph and then loops the drawing repeatedly till you click the stop button - a classic way to work with EZ Math Movie.

Study the source code. The graph is set up in the before loop code. Then two things happen repeatedly in the loop code. First, a random x- and y-coordinate are generated, and a point is plotted at those coordinates. Second, a pair of random (x, y) endpoints are generated, and a line segment is drawn between them. As the program runs, the points and line segments are scattered about the graph.

You will have to press the stop button to halt this program.

Running the example program

This program has one of the classic EZ Math Movie forms. The form works this way:

In our example program each drawing cycle consists of:
