ABSTRACT:
Polygon reshaping methods either add or subtract sides of lines of a polygon around an object of a digitized frame of picture stock. A line may be added by selecting a line of a polygon and adding a point to the line, thereby defining two lines with the point as their vertex. The point may be move along the line and away from the line to create an angle between the two lines on either side of the vertex. A line may be subtracted from a polygon either by selecting a line of the polygon and simply deleting it or by selecting a vertex of the polygon and deleting the two lines which shared the vertex. In the former line-removal case, the now-free endpoints of the lines adjacent to the removed line are moved and connected at a point defined along the removed line. In the latter vertex-removal case, a new line is drawn between the now-free endpoints of the lines which were respectively adjacent the removed lines. Any of the changes made to a particularly polygon may be propagated or interpolated through other frames of the shot.
