    Methods

    • 判断点相对于直线的位置

      使用叉积计算点相对于直线的位置关系。 这是一个基础的几何算法，用于判断点在直线的哪一侧。

      Parameters

      Returns number

      -1=点在直线左侧，0=点在直线上，1=点在直线右侧

    • 调整角度到正值范围

      将角度调整到[0, 2π)范围内。

      Parameters

      • angle: number

        输入角度（弧度）

      Returns number

      调整后的角度

    • 根据位置判断获取有效交点

      这是一个复杂的逻辑判断函数，根据两个端点相对于交点的位置关系， 确定哪些交点是有效的（在线段范围内）。

      Parameters

      • firstEndpointPosition: string

        第一个端点的位置关系

      • secondEndpointPosition: string

        第二个端点的位置关系

      • firstIntersection: Point2D

        第一个交点

      • secondIntersection: Point2D

        第二个交点

      Returns Point2D[]

      有效交点数组

    • 数值相等判断

      在指定容差范围内判断两个数值是否相等。

      Parameters

      • firstValue: number

        第一个数值

      • secondValue: number

        第二个数值

      • tolerance: number

        容差值

      Returns boolean

      如果在容差范围内相等返回true

    • 判断点相对于两个边界点的位置

      判断一个点相对于两个边界点的位置关系。

      Parameters

      • pointCoordinate: number

        要判断的点的坐标

      • leftBoundary: number

        左边界点坐标

      • rightBoundary: number

        右边界点坐标

      Returns string

      位置关系字符串
