摘要
本文研究和开发了一个变分几何的参数化造型系统(VGPDA)。该系统能自动生成约束方程,较好地处理约束一致性问题,并将约束一致性判断与约束方程的求解相结合,使得求解过程方便、快速;此外,VGPDA 的另一独特之处在于运用符号微分方法提高了算法的精度和可靠性。
In this paper,a variational geometry based parametric modelling System (VGPDA) is explored and developed.The system consists mainly of the following functions: (1) Establishing automatically the constraint equations;(2) Detection of constraint consistency;(3) Fast solving of the constraint equations.Especially,a symbolic differential method is used to improve the accuracy and reliability of problem solving.
