The standard Brillouin zone and schematic structures of 3D PPCs with a spherical atom in simple lattice
such as diamond, bcc, fcc and sc lattices can be found in many textbooks and reports [38-43].
Suppose a simple lattice
polygon P has area A, B boundary points and I interior points, then
Traditional ornamentation is also reduced to basics, with curved ridgelines straightened and gable end ornament simplified to a simple lattice
framework inspired by traditional grain racks.
This direct connection is visible not only in the skins' registration of the identity and texture of the surfaces from which they were modeled, but also in the ways in which they record the three-dimensional nature of their mold: in the scabrous buildup that accumulates wherever the skin encounters a bump or a corner and especially in the simple lattices
, made of slender bamboo poles, that Bucher used to give her skins the degree of relief necessary to negotiate inset paneling or the depth of door frames.
What Pederson filled the gallery with on this occasion was mostly wood, slender dowels or delicate slivers of plywood, arranged into simple lattices
held together with lengths of colored thread or yarn (all works Untitled, 2010).
