Subtraction of Planes


When a negative plane overlaps a positive plane, space appears to have been subtracted from the positive plane. The resulting shape shows a missing portion where the negative plane merges with the background. Sometimes subtraction leads to loose parts.

A smaller negative plane can be completely contained within a larger positive plane.
