基于网格测地线的特征重用布局方法研究

Research on Feature Reuse Layout Method Based on Mesh Geodesics

针对传统的规则曲面特征造型设计方法不能满足高复杂度的设计要求,在设计工作中经常需要进行繁琐的高复杂度的特征设计工作,而仅仅依靠设计者的交互编辑,存在精度差,效率低的问题,提出一种以网格测地距离为度量的特征自动重用的布局规划设计方法。通过实例表明,该方法能得到稳定的网格模型,明显减少用户交互,实现在网格曲面模型上快速实现特征模型的设计重用。

Aiming at the issue that the traditional ruled surface feature design method cannot meet the high complexity design requirements,it is necessary to carry out highly complex and cumbersome feature design work in the content.However,relying solely on the designer′s interactive editing,poor precision and low efficiency is likely to occur.A layout planning design method based on the mesh geodesic distance is proposed.The example shows that the method can obtain a stable mesh model and significantly reduce user interaction.Fast reuse of the design of the feature model on the mesh surface model has been realized,
