An information handling system and method includes a display screen for displaying a three dimensional image captured via a three dimensional camera and the processor to detect a selection of a first pixel within the three dimensional image that is proximate to an edge of a first object in the three dimensional image and redefine the selected first pixel to snap to a second pixel within the three dimensional image on the edge of the first object, wherein the second pixel has a large disparity within the three dimensional image and the processor to detect a selection of a third pixel within the three dimensional image that is proximate to an edge of a second object in the three dimensional image and redefine the selected third pixel to snap to a fourth pixel within the three dimensional image on the edge of the second object, wherein the fourth pixel has a large disparity within the three dimensional image.
