摘要： A graphics system which accelerates generation of pixels including transparent objects by simply adding more rendering devices. The system has composition means and a plurality of rendering devices each comprising a geometric processor, a rendering processor and a frame memory that holds color, depth and weight data in a screen bit map format. Given a plurality of sets of color, depth and weight data about any one pixel position from the frame memories, the composition means first compares the depth data, and multiplies successively the weight and color data starting with those corresponding to the depth data closest to the foreground, thereby generating new pixel data. The system thus permits merging of transparent objects.

摘要： A graphic processing apparatus for generating, displaying or printing characters and graphic data. A successive column access is used in which a row address is designated for access to a memory and data in different column addresses within the designated same row address are successively accessed and buffer means for buffering a series of data between an access by a processor and an access to a memory is provided. A program and image information for display are stored in a main memory. A frame buffer and the main memory are integrally configured simply and small in size.

摘要： In a case where a graphic image segment of which positional information is defined in a world coordinate system and of which size information is defined in a device coordinate system is developed to be displayed on a multi-window screen, the development processing performance is improved in peripheral portions of the window. A rectangular development area (first development area) associated with the window is expanded with consideration of a size information of a graphic segment so as to obtain a second development area. The second development area is compared with a rectangular area (an existence area) circumscribing a graphic image represented only with positional information of the graphic segment. As a result, whether or not the graphic segment is to be developed is determined. The first development area is reduced with consideration of size information of the graphic segment to produce a third development area. The third development area is compared with the existence area to decide whether or not the clipping operation is necessary for the graphic segment.
