The derivation of the <i>Sh</i>-matrices using the <i>T</i>-matrix method allows the shape-dependent parameters to be separated
from size- and refractive-index-dependent parameters. This separation also allows for the surface integrals to be solved
and for analytic solutions to the light-scattering from some irregular morphologies to be found. In this manuscript we
derive solutions for capsule-shaped and bi-sphere particles. We analyze the two-dimensional patterns resulting from
these two different simulants of <i>B. subtilis</i> spores. The large differences between the patterns suggest that simple
approximations to complicated particles may not be adequate.
