ABSTRACT:
A method and apparatus for deleting and rescanning areas of a horizon display on a computer monitor is disclosed. A cursor, controlled by a pointing device such as a mouse, is directed to a first area on the monitor which is adjacent a second area of the horizon which is described to be deleted and rescanned. The cursor is dragged from the first area across the second area while a user pushes the control button of the mouse thereby defining coordinates of an area for which all points are to be deleted. The points in the first area are scanned to designate them as seed points. Such seed points are used to pick horizon points in the second area. Such picked points are then used to fill-in the second area.
