使用VB查找两条线的交点 [英] Finding the intersection point of two lines using VB

问题描述

大家好：

我需要帮助解决我在VB中编写函数的问题。 我需要找到两条线的交点。 每条线由线穿过的点（称为[x，y]）和线的角度（以弧度表示）定义。 
线条永远不会平行 - 它们总是会在某个时刻交叉。 我可以在相交线上找到的所有材料按照每个线由开始/结束点定义来讨论它们......这对我没有帮助。 任何人都可以给我一些
的建议吗？

I need some help with a problem I'm having trying to write a function in VB.  I need to find the intersection point of two lines.  Each line is defined by a point (call it [x,y]) that the line passes through, and the angle (in radians) of the line.  The lines will never be parallel - they will always cross at some point.  All the material I can find on intersecting lines discusses them in terms of each line being defined by a start/end point...which doesn't help me.  Can anyone give me some advice?

谢谢。

推荐答案

我可以在相交线上找到的所有材料按照由起点/终点定义的每一行来讨论它们......这对我没有帮助。 任何人都可以给我一些建议吗？

您可能搜索不当。交点是根据线方程的标准形式计算的。

You might be searching incorrectly. The intersection is calculated from the standard form for the line equation.

第一个搜索是"如何将一条线的等式从斜率截距形式转换为标准形式"。 然后你可以搜索拦截解决方案。

The first search is "how to convert the equation of a line from slope intercept form to standard form".  Then you can search for the intercept solution.
