二次曲面相贯线真三维动画的实现

The Implement of TruethreeDimension Animation of Intersected Curves of Quadric Surface

对工程二次曲面的相交情况进行了分析，提出了相贯线的三维仿真显示方法，在微机上实现了相贯线的真三维动画及其三面投影的同步动画，在屏幕上可清晰、真实显示工程二次曲面相贯线各种位置的形状及其连续变化过程，为研究相贯线的性质及分析相贯线的投影趋势提供了科学手段．

In this paper,the intersection condition of quadric surfaces is analysed, the threedimensional simulation display method of intersected curves is proposed also. The truethreedimension animation of intersected curves and simulataneous animation of three plane projection of intersected curves are implemented on micro computer. The various shapes and the continuing variable process of intersected curves of quadric surfaces can be displayed on computer screen clearly.This provides modern science means for people to study the property of intersected curves and analyses the development of projection of intersected curves.
