Description :

An idealised truncation of a
tetrahedron
from infinty to +infinity.
The model is scaled to have a circumsphere of constant size.
The tetrahedron does not have central symmetry, and hence the limit of
truncation at the two extreme ratios produces different models. This
is seen as a break in the animation cycle at the switch from +infinity
to infinity.
