曲面

This paper presented a method for tracing the intersections of two implicit surfaces.the most obvious advantage of this method is: when tracing the intersections, it could quickly get the next tracing point by intersecting this square plane with the two implicit surfaces.

该方法最主要的优点是：在跟踪隐式曲面的交线时，在前一个跟踪交点已经求得的情况下，利用正方形与两个隐式曲面的交点，即可快速有效地求出下一个跟踪点，而不用涉及迭代收敛的判断。
