§9-3 两曲面立体相贯

一、概述. 两曲面立体的相贯线为封闭的空间曲线。 由于相贯线既属于甲立体表面,同时又属于乙立体表面,是两立体表面的共有线。为此,求相贯线的实质是求两立体表面上的一系列共有点,然后依次光滑地相连,并判别可见性,描深。. §9-3 两曲面立体相贯. 返 回. 二、 利用积聚性投影求相贯线. 三、 辅助面法求相贯线. 上一节. 四、 复合相贯线. 五、 相贯线的特殊情况及相贯线投影的趋势. 下一节. 退 出. 两曲面立体相交.

  1. 一、概述 两曲面立体的相贯线为封闭的空间曲线。 由于相贯线既属于甲立体表面,同时又属于乙立体表面,是两立体表面的共有线。为此,求相贯线的实质是求两立体表面上的一系列共有点,然后依次光滑地相连,并判别可见性,描深。 §9-3 两曲面立体相贯 返 回 二、利用积聚性投影求相贯线 三、辅助面法求相贯线 上一节 四、复合相贯线 五、相贯线的特殊情况及相贯线投影的趋势 下一节 退 出

  2. 两曲面立体相交
