This paper presents interpolators that are capable of generating 2D curves in general implicit forms and 3D curves in general parametric forms. In contrast to the existing interpolators, which utilize complicated algorithms to meet the interpolation requirements such as maintaining high accuracy and constant feedrate, the proposed interpolators utilize a simple algorithm and a feedback action which corrects the interpolation results to meet the interpolation requirements.
