摘要：

Methods for defining G(2) curves with conic segments are introduced in this paper, the conic is represented by implicit equation. Firstly, a method for interpolating two given endpoints, two given tangent directions at the endpoints as well as a curvature at either endpoint is presented. Secondly, a method for interpolating a point sequence in a plane with conic segments is offered. Lastly, a method for fitting a point sequence in a plane is given. The methods are very robust for any 2D data sequences. The global G(2) continuity can be hold whether the data set is open or closed.
