Types

type ArgsCheckXYInArea

type ArgsCheckXYInArea struct {
	//点坐标
	Point MapMathArgs.ParamsPoint
	//分区范围
	Area ParamsArea
}

ArgsCheckXYInArea 检查点和面的数学问题，点是否在面内 采用矩阵关系处理 测试耗时：10,000次 / 0.038秒

type ArgsCheckXYInAreaList

type ArgsCheckXYInAreaList struct {
	//检查的点
	CheckPoint MapMathArgs.ParamsPoint
	//分区数据
	AreaDataList []ParamsArea
}

type ArgsGetCircleByPoint

type ArgsGetCircleByPoint struct {
	//圆心
	Point ParamsAreaPoint
	//半径
	Radius float64
}

ArgsGetCircleByPoint 给予一个点坐标和半径，计算圆的范围点数据参数

type ParamsArea
