RESEARCH ON DEVELOPING AN ALGORITHM AND A SOFTWARE TO DRAW BEZIER CURVES

Abstract

This paper presents a research on method ofdesigning Bezier curves in
CAD/CAM environment. A software called “Cong cu xay dung duong cong Bezier”
written by Matlab 2012 for designing and editting Bezier curves is introduced
here. This tool for designing Bezier curves can be used as a stand-alone program
to design free- form curves. By this tool, the user can changes control points to
flexibly and visually control the shape of the curve for designing. This is the base
to design complex 3D surfaces in modern manufacturing. This paper and the tool
for designing Bezier curves can be used for reference in research and training
about the formation of free form curves, free form surfaces in CAD/CAM
softwares. This permits us to understand better and effectively use the softwares
for designing and manufacturing
