   The first animations truncate a regular polyhedron to the mid-points of its edges, then switch to the dual model and truncate back from the mid-points of its edges.

The second animations show the full range of an idealised truncation. The edges are treated as lines rather than line segments. The edges are cut in a ratio that ranges from -infinity to +infinity.

At the extremes of the range the circumsphere of the model grows to become infinitely large. In order to view the transformation the truncated model is scaled to maintain the circumsphere at a constant size. The effect on the base polyhedron is to shrink it into the centre at the extreme ratios.

The animations were made with the following scripts
