ABSTRACT:
A user-friendly procedure for the generation and display of geometric figures on a graphics screen uses a cursor placement device such as a joy stick to both define the initial position and size of the geometrical figure. Two specific examples are described: the generation of a circle and the generation of a square or rectangle. In the first example, the cursor is first positioned to point to the center of the circle at which point a small circle is drawn. The circle is expanded in response to the pressing of a designated key by the user until the desired size is attained. In the second example, the pointing by the cursor is to the upper left corner of the square or rectangle, and the square or rectangle is then expanded in response to the user deflecting the joy stick down and to the right.
