ABSTRACT:
A polar controller takes user-input to specify the creation of graphic shapes. An interface of the polar controller receives from a user a start angle, a stop angle, a step angle and a radius length for the graphic shape. A polar execution engine of the polar controller generates the graphic shape based on the start angle, the stop angle, the step angle and the radius length. For example, when the radius length is expressed as a function of angle, the polar controller is able to draw spiral-like shapes.
