摘要: A novel algorithm for approximating planar algebraic curve with biarcs is presented. With reasonable selection of split points the segmented according to convexity and monotonicity. For every segment biarc constructed based on tangents two end careful common tangent point biarc. The whole approximate keeps some important geometric features original such as convexity, monotonicity G 1 continuity easy operate achieve in NC machining. Numerical experiments show that reliable efficient. approximation error can be controlled by recursive call algorithm. As a direct application, we apply calculate offsets curve.
