PointDCrossProduct(PointD, PointD) 方法

Calculates the 2D cross product magnitude 计算二维叉积大小

Definition

命名空间: DeploySharp.Data
程序集: DeploySharp (在 DeploySharp.dll 中) 版本:0.0.4+6e8a2e904469617cd59619d666c0e272985c0e33
C#
public static double CrossProduct(
	PointD p1,
	PointD p2
)

参数

p1  PointD
First vector 第一个向量
p2  PointD
Second vector 第二个向量

返回值

Double
Cross product magnitude 叉积大小

备注

The cross product in 2D returns a scalar representing the signed area of the parallelogram spanned by the two vectors. 二维叉积返回一个标量,表示两个向量所张成的平行四边形的有符号面积。
