基于悬链线的曲线保长度伸缩变形算法
A LENGTH-PRESERVING EXTENSION DEFORMATION ALGORITHM OF CURVE BASED ON CATENARY
摘要
Abstract
In order to apply the catenary theory to the curve extension deforming process,a length-preserving deformation algorithm is proposed.The local coordinate system of the curve segment was created,and the shape control equation of the curve segment under the local coordinate system was established.The curve segment was calculated by adjusting the shape parameters.The deformation result of the whole curve was calculated by coordinate and geometric transformations.The numerical examples verified the validity and controllability of the method.关键词
