Methods

Name Description
constructor(cp?: CurvePrimitive, fractionTol: number = Geometry.smallFraction): UniformStrokeCollector Constructor.  
announceIntervalForUniformStepStrokes(_c: CurvePrimitive, numStrokes: number, f0: number, f1: number): void Announce uniformly distributed fractions in the fractional interval.  
announcePointTangent(_p: Point3d, f: number, _v: Vector3d): void Announce a single fraction.  
announceSegmentInterval(_c: CurvePrimitive, _p0: Point3d, _p1: Point3d, _numStrokes: number, f0: number, f1: number): void Announce the fractional span of the segment.  
claimFractions(remove01: boolean = false): number[] Retrieve the collected fractions, optionally removing 0 and 1 first.  
claimLineString(result?: LineString3d): undefined | LineString3d Create a LineString3d by evaluating the curve at the collected fractions.  
endCurvePrimitive(_c: CurvePrimitive): void Announce that all data about the curve has been announced (ignored).  
endParentCurvePrimitive(_c: CurvePrimitive): void Announce that all data about the parent curve has been announced (ignored).  
needPrimaryGeometryForStrokes(): boolean Request primary geometry to avoid cached strokes.  
startCurvePrimitive(cp: CurvePrimitive): void Announce the curve primitive that will be described in subsequent calls.  
startParentCurvePrimitive(_c: CurvePrimitive): void Announce a parent curve primitive (ignored).
