Calculates the 2nd moment of surface area about the origin by multiplying the surface area of
each triangle in the mesh by its distance from the origin (should be set to
the attachment point of the mesh). The sum of these values is the 2nd moment
of area.#' This metric is size-dependent so to compare moments in terms of shape only, set scale = TRUE.

A collection of functions for sampling and simulating 3D surfaces and objects
and estimating metrics like rugosity, fractal dimension, convexity, sphericity, circularity,
second moments of area and volume, and more.
