  • Method for determining a largest inscribed rectangular image within a union of projected quadrilateral images
    Patent number: 6729733
    Abstract: A method determines a largest rectangle on a display surface. A polygon L is drawn on a first depth plane having a depth z=1 in a depth buffer. A rectangle R is drawn with a predetermined aspect ratio on a second depth plane having a depth z=0. A center of projection is determined with a minimum depth z in a range [0,1] that maps the rectangle R into a largest rectangle S in the first depth plane so that the rectangle S remains completely inside the polygon L.
