Monotone Polygon Intersection: Geometry, Computer Applications, and Computer Graphics
This is a 1991 technical report from the RAND Corporation in Santa Monica, catalogued by the Defense Technical Information Center, treating algorithms for intersecting monotone polygons for a computing and mathematics audience. Its three figures are plain line diagrams: two piecewise-linear profiles drawn against a horizontal dashed baseline, with a third panel shading the region between an upper and a lower chain in dotted and hatched tones, giving a designer a clean model of stepped, shaded boundary regions.
