ABSTRACT:
A method and system for processing graphic objects on a computer with a memory and an attached display and performing binary constructive area geometry (CAG) operations on area-defining geometries such as rectangle, ellipses, and polygons in an object oriented operating system. The operations include the construction of an area and the display of area geometries on an external device. The system allows application programmers to efficiently develop and share software for displaying a plurality of complex views including overlapping views and translucent views.
