摘要：

Based on the method of Maxwell and Baker [7], an all-integer algorithm is developed for the rendering of elliptical curves. It is immune to problems of degeneracy and best suited for hardware implementation. At each point the algorithm provides the tangent vector and an estimate of the quantization error, all the data needed for rendering high precision elliptical arcs and generating antialiased curves.
