accumulateXYProductsInCentroidalFrame Method

  • Assemble XX, YY, XY products into a full matrix form [xx,xy,0,0; xy,yy,0,0;0,0,0,0;0,0,0,1].
  • Sandwich this between transforms with columns [vectorU, vectorV, 0000, origin]. (Column weights 0001) (only xy parts of vectors)
  • scale by detJ for the xy-only determinant of the vectors.

accumulateXYProductsInCentroidalFrame(productXX: number, productXY: number, productYY: number, area: number, origin: XAndY, vectorU: XAndY, vectorV: XAndY): void
