| Abstract: | Development of a curved surface is a new tool for CAD/CAGD(Computer Assisted Geometric Design).The definition and the deformations of planar mapping of a curved surface are presented in this paper.Then several planar mapping methods of curved surface as well as their advantages and disadvantages are analyzed.For NURBS surface is widely used in CAGD,a new planar hybrid mapping algorithm is put forward.By using this algorithm,distortions of the development are reduced.At last we give an example to validate this algorithm. |
