In this paper, we first review local counting methods for perimeter estimat
ion of piecewise smooth binary figures on square, hexagonal, and triangular
grids. We verify that better perimeter estimates, using local counting alg
orithms, can be obtained using hexagonal or triangular grids. We then compa
re surface area estimates using local counting techniques for binary three-
dimensional volumes under the three semi-regular polyhedral tilings: the cu
bic, truncated octahedral, and rhombic dodecahedral tilings. It is shown th
at for surfaces of random orientation with a uniform distribution, the expe
cted error of surface area estimates is smaller for the truncated octahedra
l and rhombic dodecahedral tilings than for the standard cubic or rectangul
ar prism tilings of space. Additional properties of these tessellations are
reviewed and potential applications of better surface area estimates are d
iscussed. (C) 1999 Academic Press.
