API Reference > geometry-core > Numerics > MomentData > accumulateTriangleMomentsXY accumulateTriangleMomentsXY Method compute moments of a triangle from the origin to the given line. Accumulate them to this.sums. If pointA is undefined, use this.origin as pointA. If this.needOrigin is set, pointB is used accumulateTriangleMomentsXY(pointA: undefined | Readonly<WritableXAndY>, pointB: Readonly<WritableXAndY>, pointC: Readonly<WritableXAndY>): void Parameter Type Description pointA undefined | Readonly<WritableXAndY> pointB Readonly<WritableXAndY> pointC Readonly<WritableXAndY> Returns - void Defined in geometry4d/MomentData.ts Line 302 Last Updated: 12 June, 2024
