Now that computer displays with vector and character drawing capabilities are becoming a common form of on-line graphic output device, interest has turned toward providing a curvilinear display capability. Naturally, curves can be drawn as a series of short vectors stored in display memory, but the goal of current research is to provide hardware which draws a curve by generating such vectors, or perhaps, continuous beam motion, from a concise specification of a curve segment.
Cohen et al. (Wed,) studied this question.
