API Reference > geometry-core > Curve > RegionOps > computeXYAreaMoments computeXYAreaMoments MethodStatic Return moment sums for a loop, parity region, or union region. If rawMomentData is the MomentData returned by computeXYAreaMoments, convert to principal axes and moments with call principalMomentData = MomentData.inertiaProductsToPrincipalAxes (rawMomentData.origin, rawMomentData.sums); computeXYAreaMoments(root: AnyRegion): MomentData | undefined Parameter Type Description root AnyRegion any Loop, ParityRegion, or UnionRegion. Returns - MomentData | undefined Defined in core/geometry/src/curve/RegionOps.ts Line 276 Last Updated: 13 June, 2024
