摘要

Current graphical systems include primitives to draw straight-line segments, circles, Bezier curves and surfaces, NURBS (Non-Uniform Rational B-Splines), but many of them fail displaying curve singularities (self-intersections) correctly. This paper introduces a fast and robust non-uniform binary space partition (BSP) algorithm for implicit curves possibly with self-intersections and other differentiable singularities. These singularities are computed without using traditional differential techniques.
