public getPointAt(u: number): Vector

Returns a vector for point at relative position in curve according to arc length getPointAt(u: number): T;

Parameters

  • u: number

Returns

Vector

public getPoints(divisions?: number): Vector[]

Get sequence of points using getPoint( t ) getPoints(divisions?: number): T[];

Parameters

  • divisions?: number optional

Returns

Vector[]

public getSpacedPoints(divisions?: number): Vector[]

Get sequence of equi-spaced points using getPointAt( u ) getSpacedPoints(divisions?: number): T[];

Parameters
