查询词典 intersection point

With the boundary point and the known adjacent relations, an overall marching procedure can go on and the iteration process stops until the intersection curve is self-closed or reaches the border of the composite surface. In the later case, the marching must be repeated from the starting point in the reverse direction until the intersection curve reaches the other border of the composite surface.

由一个交点出发，通过计算跟踪方向和跟踪步长，迭代计算出下一个精确的交点；利用边界点和近曲面点计算方法，根据曲面片的拓扑关系找到交线所经过的下一张曲面片，从而使跟踪过程继续下去，直至形成封闭交线环而停止该交线段的跟踪，或到达复合曲面的边界后由首交点反向跟踪到达复合曲面的另一边界。

According to the principle of the diameter of a circle corresponding to the right angle and the principle of short side for little angle in right triangle, projecting the initially-chosen point to the hyper-planes of the linear equation group in which every linear equation can be regarded as a hyper-plane and the projection points can be obtained. The initially-chosen point, and one arbitrary projection point, and the solution point are all on the surface of the relative hyper-geometry ball, therein-to, there is a projection point which is nearest to the solution point and it can be regarded as the next iterative initially-chosen point, so the solution problem of the linear equation group can be changed as an iterative problem of approaching the solution on the surface of a hyper-geometry ball.

根据直径对应的圆周角足直角以及直角三角形中短边对小角的原理进一步知道，当将初始点向线性方程组中各个方程所代表的超平面上投影得到投影点时，初始点和其任何一个投影点及方程组的解点都将位于一个相应的超球面上，其中必定存在一个投影点离问题解点的距离最短，即把该点作为下一次迭代的初始点，从而可将线性方程组求解的问题变成球面上逼近解点的迭代问题。
