On the surface area of the ellipsoid [PDF]

open access: yesMathematics of Computation, 1979
An expression is derived for the surface area of an ellipsoid in the form of a convergent series. The derivation is based upon an n -point Gauss-Chebyshev numerical quadrature. The rate of convergence and accuracy of the formula are demonstrated by computing the surface area of several ...

Surface Area Estimation in Practice [PDF]

open access: yes, 2003
Consider a complex, convoluted three dimensional object that has been digitized and is available as a set of voxels. We describe a fast, practical scheme for delineating a region of interest on the surface of the object and estimating its original area. The voxel representation is maintained and no triangulation is carried out.
