연속인 곡률을 갖는 삼차 베지에 곡선에 관한 연구

Abstract

Bezier curves have been applied in many fields such as the field of CAD/CAM to help in designing desired objects with curve or curved surface in recent 30 years. Especially, the various fonts can be created by using the cubic Bezier curve. For example, alphabet "R" is constructed by connecting 28 Bezier curves in this paper. The research of this paper is the study to approximate 'R' which is composed of curves to become the curvature continuous. It showed the study that makes the tangent continuous approximated to become the curvature continuous in the connection points of Bezier curves.
