API Reference > geometry-core > Numerics > MomentData > accumulateTriangleToLineStringMomentsXY accumulateTriangleToLineStringMomentsXY Method compute moments of triangles from a base point to the given linestring. Accumulate them to this.sums. If pointA is undefined, use this.origin as pointA. If this.needOrigin is set, the first point of the array is captured as local origin for subsequent sums. accumulateTriangleToLineStringMomentsXY(sweepBase: undefined | Readonly<WritableXAndY>, points: GrowableXYZArray): void Parameter Type Description sweepBase undefined | Readonly<WritableXAndY> points GrowableXYZArray Returns - void Defined in geometry4d/MomentData.ts Line 365 Last Updated: 11 June, 2024
