    摘要: 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.

    摘要: An object-oriented graphic system performs a scan conversion process on a geometric figure with edges. The figure is represented by a graphic object which contains data describing the edges and a method for traversing the edges to outline the figure. The scan conversion is performed by loading the graphic object into a memory and using the graphic object data and methods to generate a plurality of edge objects, each of which represents one of the edges. The edge objects are then manipulated by means of an edge engine object to generate a plurality of scan lines of varying numbers of pixels which scan lines together fill or frame the geometric figure and complete the scan conversion. The geometric figure can be displayed by displaying the pixels in the scan lines.

    摘要: An object-oriented graphic system is disclosed including a processor with an attached display, storage and object-oriented operating system. The graphic system builds a component object in the storage of the processor for managing graphic processing. The processor includes an object for connecting one or more graphic devices to various objects responsible for tasks such as graphic accelerators, frame buffers, page description languages and vector engines. The system is fully extensible and includes polymorphic processing built into each of the support objects.
