morf lets you modify an object by blending the shape of two objects together - "morphing" between the two according to a percentage. Any polyhedra may be used, as long as the number of vertices are equal and the vertices are in the same order.
You also have the ability to animate the morphing, creating smooth transitions between target shapes. Keyframes are only created when you specify them, making the animation easier to adjust afterwards.
A common use for morphing is facial animation.
morf is fully supported under version 3.1 and higher of trueSpace.
