Patent number: 5245700Abstract: A system and method in a graphics environment ensures that a line drawn upon the surface of a polygon is always visible to a user of the graphics system. In a Z-buffered environment the range of depth values contained therein are set to the 75% of the total capacity which is considered closest to the surface of a display screen. The line is then drawn into this 75% set of Z-buffer depth values. A shift is then computed, based upon the normal to the polygon in device coordinates. This shift is then added to the previously set 75% range of Z-buffer depth values. The polygon is then drawn at a depth equal to the previously set range plus the shift. Thus, the line will always be visible since, the polygon surface will always be considered by a graphics adapter to be deeper than the line contained on the surface thereof.Type: GrantFiled: November 21, 1989Date of Patent: September 14, 1993Assignee: International Business Machines CorporationInventor: Gordon C.
