Abstract :
The technique of placing directed line segments at grid points, known as hedgehogging, which has been used for visualizing 2D vector fields, is considered. A means of rapidly rendering a slice of a 3D field, suitable for a bilevel display, is provided. Shape and shadowing are used to disambiguate orientation. Liberal use of lookup tables makes the technique very fast
