KPolylineCurve2d interface

KPolylineCurve2d 类代表着二维空间中的一个折线段。

The KPolylineCurve2d class represents a polyline in 2d space.

Signature:

export interface KPolylineCurve2d extends KBoundedCurve2d 

Links: export interface KPolylineCurve2d extends KBoundedCurve2d

Extends: KBoundedCurve2d

Properties

Property	Modifiers	Type	Description
params	readonly	number[]	获取当前折线段每个顶点的弧长参数。 Get arc length parameters of all the vertices of the polyline.
points	readonly	KPoint2d[]	获取当前折线段的所有顶点。 Get all the vertices of the polyline.

Methods

Method	Description
getTangent(point)	获得折线段上一点处的切向量。 注意：该函数调用需要确保传入点在折线段上。 Get tangent vector of a point on the polyline. NOTE: the caller needs to make sure the point is on the polyline.
