//半径比可以接受负值的输入，如果输入负值，则会按照其绝对值进行绘制；
//半径比越小，椭圆就越扁，半径比越大，椭圆就越圆，但是不能超过1；
//majorAxis主轴new Vector3d(0, 0, 0)，主轴长度为0（短轴长度=长轴长度*半径比，也是0），画不出来
//majorAxis主轴，主轴长度就是长轴半径；
//主轴不仅决定了长轴长度，还决定了长轴的方向；
//起止角度startAngle/endAngle单位为弧度，而不是角度；
//起止角度支持负值，夹角为与主轴正方向，逆时针为正，顺时针为负；
//如果起始角度大于终止角度，那么就按照起始角度逆时针旋转至终止角度进行绘制；
//如果起止角度相等，例如都是0，则绘制一圈360度

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；
