A note on surface inflections


This paper gives an example of a surface whose intersections with parallel planes in three orthogonal directions have no inflections, but there are inflections in the intersections with parallel planes defined in other directions. This surface would pass a quality inspection test used by many designers. Methods are needed for the detection and display of… (More)
