osculating plane

基本解釋

A tracing algorithm for calculating the intersection curves of two free-form surfaces by using their osculating plane is presented in this paper.
提出了一種利用密切平麪對兩自由曲麪進行追蹤求交的算法。
A cusp curve, an osculating curve and a cave and convex boundary line divided the coupler plane into some portions, the feature is different in a different portion of coupler curve.
其方法是，用尖點曲線、自切點曲線及凹凸分界線把連桿平麪劃分出若乾個區(qū)域，不同區(qū)域內的連桿曲線具有各自的類別特征。
