Surface and surface intersection ( 551 ) is one of the key tasks in cagd 曲面求交(ssi)是cagd中的一个重要课题。
Based on parameter-parameter surfaces intersection curve, the differential geometric properties of implicit-implicit ones are in detail in the paper . these properties include tangents, curvature vector and higher-order derivative vector in cases of transversal intersection and tangent intersection 本文在参?参曲面交线基础上,详细推导了隐?隐形式两曲面空间交线的微分几何性质,这些性质包括截交及切交下的切矢,曲率矢以及高阶导矢等。
