计算机辅助工业设计中NURBS曲线质量控制方法研究

Research on control method of NURBS curve quality in CAID

在基于NURBS技术的计算机辅助工业设计(CAID)软件中,曲线的质量直接影响到曲面的质量以及后期曲面编辑与修改的难易程度,因此,好的曲线是构建优质曲面的核心与关键;从NURBS曲线的基本理论出发,基于CAID软件平台,结合实际经验,对NURBS曲线质量控制方法进行了研究,提出了提高NURBS曲线质量的实现方案。

In CAID software based on NURBS technology, the quality of curve directly affects the quality of surface and the degree of difficuhy for post-editing and modification of the surface, so high quality curve is the key to build high-quality surface. Combining the basic theory of NURBS curve with practical experience, the study on the method of controlling the quality of the NURBS curves is conducted, and the implementation scheme is proposed to improve the quality of the NURBS curve.
