Carbon takes many different forms, each with its own electronic structure and
has a fantastic range of properties. As well as graphite/diamond, a hexagonal di-
amond called londsdaleite, and amorphous carbons of sp2, sp3 and mixed natures
there are all the fullerenes, graphene, nanotubes etc. Fortunately, their different
electronic structures take distinct geometrical forms, so that deducing the geometry
of a sample that has been simulated is a crucial step towards understanding its
properties. Visualization is essential for understanding sample geometries. AViz [1]
is an Atomistic Vizualization package developed at the Technion that can be freely
downloaded and installed. Both still and animated AViz implementations for view-
ing data from our atomistic simulations of carbon allotropes enable understanding
of the simulation results and when compared with laboratory experiments and the-
oretical models provide insight into nanodiamond growth, gas flow in nanotubes,
nanotube vibrations and other topics of current research interest.
