Abstract

A method is described to give the user interactive feedback when trying to create perfect circles and regular polygons, and ellipses of specific dimensions. Users of an interactive draw graphics system may want a facility that will give them interactive and easy to read feedback about the size and shape of the circle, ellipse or regular polygon that they are drawing. Even though grids are provided in the graphics spaces, these may prove hard to read and not as accurate as the user may need. The new method provides an option in the graphic description pop-down which turns "Creation Feedback" facility either on or off. When this facility is turned on, and the user is creating an ellipse, circle, or a regular closed polygon, the system will display the width and height of the object as it is being created.

A Method to Provide Width And Height Information During Creation of Circles, Ellipses, And Regular Polygons

A method is described to give the user interactive feedback when trying to create perfect circles and regular polygons, and ellipses of specific dimensions. Users of an interactive draw graphics system may want a facility that will give them interactive and easy to read feedback about the size and shape of the circle, ellipse or regular polygon that they are drawing. Even though grids are provided in the graphics spaces, these may prove hard to read and not as accurate as the user may need. The new method provides an option in the graphic description pop-down which turns "Creation Feedback" facility either on or off. When this facility is turned on, and the user is creating an ellipse, circle, or a regular closed polygon, the system will display the width and height of the object as it is being created. Since the system provides "rubberbanding" of these objects during creation, the user can watch the object grow and shrink in response to the movements he is making with the mouse. With the information provided about the current size of his object, he will be able to determine when it is precisely the size he needs. If the "Creation Feedback" option is turned off, the width and height information will not appear. The user may prefer this if precision is not a high priority and he wants his screen to be as uncluttered as possible.

The method gives the user hig...
