Title: Picture generating method
Inventor: MATSUDA KAZUHIKO
IPC: G06T15/80
Filed: 1989-10-24
Abstract: PURPOSE:To omit the arithmetic processing and to shorten the processing time by calculating intersections of a virtual picture element set between a picture element on the boundary of a display object and an adjacent picture element only with respect to intersection objects of the picture element on the boundary and the adjacent picture element. CONSTITUTION:When all of actual picture elements adjacent to a virtual picture element (g) intersect a single object at the time of calculating intersections of the virtual picture element (g) set between a picture element Gi,j on the boundaries of display objects 3 and 4 and an adjacent picture element, the virtual picture element intersects the object. Consequently, an average value of sampling luminance values of the actual picture element Gi,j and the adjacent picture element is defined as the actual luminance value of the picture element Gi,j. When the sight line of the picture element adjacent to the picture element Gi,j intersect an object other than the object which the sight line of the picture element Gi,j intersects, intersections are calculated only with respect to the object which the sight line of the picture element Gi,j intersects and the object which that of the adjacent picture element intersects. Thus, the arithmetic processing is omitted to shorten the processing time.
