UNCHAINED GEOMETRY - Home Page

A transcendental function (zero-contours highlighted in white). An algebraic representation for a particular surface is not unique. A plane passing through the origin is specified by ax+by+cz, for example, and the same plane is described by a = b = c = 1 and by a = b = c = 1/3, but only the latter yields a plane normal (a, b, c) of unit length. ................
