Radius Ratio is
a set of animations that demonstrates
properties of the spherical holes
formed when uniform spheres are
packed. Cubic, octahedral and tetrahedral
packing arrangements may be examined
without anything in the holes,
and with the repective holes filled.
The sizes of the various holes
relative to the spheres being packed
are shown, which can lead students
into an exploration of the radius
ratio concept. An example is given
of computing the relative size
of an octahedral hole..
