addSecondMomentVolumeProducts MethodStatic

Accumulate to the matrix of volume products of a polygon with respect to an origin.

  • The polygon is assumed to be planar and non-self-intersecting.
  • Accumulated values are integrals over tetrahedra from the origin to triangles on the polygon.

addSecondMomentVolumeProducts(points: IndexedXYZCollection, origin: Point3d, moments: Matrix4d): void

Parameter Type Description
points IndexedXYZCollection array of points around the polygon. Final closure point is not needed.
origin Point3d origin for tetrahedra
moments Matrix4d 4x4 matrix where products are accumulated.

Returns - void
