Abstract
The use of 3D computer generated models is a rapidly
growing part of the animation industry. But the established
modelling techniques, using polygons or parametric patches,
are not the best to define characters which can change their
shape as they move. A newer method, using iso-surfaces in a
scalar field, enables us to create models that can make the
dynamic shape changes seen in hand animation. We call such
models Soft Objects.
From the user's point of view, a soft object is built from primitive
key objects that blend to form a compound shape. In this paper, we
examine some of the problems of choosing suitable keys and introduce
some new field functions that increase the range of shapes available
as keys.
