addSecondMomentAreaProducts MethodStatic
Accumulate to the matrix of area 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 triangles from point 0 of the polygon to other edges of the polygon.
- Integral over each triangle is transformed to integrals from the given origin.
