三点法画圆的预备知识（点径法和两点法相对比较简单，不作详述）：

思路：

• 已知三个点：p1点p2点p3点
• 求出两个向量v1(p1-p2),v2(p2-p3);
• 上述两个向量叉乘，得到圆所在平面的法向量n=v1×v2；
• 上述两个向量分别和n叉乘，得到两条直径的方向向量n1=v1×n,n2=v2×n;
• 求出两个中点m1(p1,p2之间)m2(p2,p3之间);
• 根据两个中点和两个方向向量，得到两个直线的点向式方程L1，L2;
• 联立两个方程，求出交点（也就是圆心）的坐标表达式

两个点向式方程

联立求出圆心坐标表达式

注意事项：

上述表达式中，分母可能为0；

如果圆的平面在XY平面，那么z坐标表达式的分母则为0，会导致错误；

有两种解决方案(等效的)：

方案一：

在使用坐标表达式之前对分母进行判定，如果分母为0，则表示该坐标为0，而不用调用坐标表达式；

方案二：

使用圆所在平面的法向量进行判定，如果法向量的x，y坐标都是0，说明圆所在平面为xy平面，那么z就可以直接赋值0，而不用调用坐标表达式；

角度测试

• GetAngleTo的返回值为弧度值；
• 返回值介于0-180度（0-π）之间；
• 不会有负值；
