■ 論文概要(和文400字程度、英文100ワード程度)
In this paper, we propose a framework of ``fractal deformation'' 
using displacement vectors
based on ``extended Iterated Shuffle Transformation (ext-IST)''.
An ext-unit-IST is a one-to-one and onto mapping that 
is extended from a unit-IST, which we have proposed, 
and is basically defined on a code space.
When the mapping is applied on a geometric space, a fractal-like repeated structure,
which is referred to as ``local resemblance in space/scale directions'',
is constructed on the relationship between points on the domain and those on the range.
By applying the mapping to displacement vectors given on a geometric shape,
the shape can be deformed in the fractal-like repeated manner.
This fractal deformation is easy to control by changing the displacement vectors intuitively.
In addition, a continuous transition between
a continuous deformation and a fractal deformation can be realized.
We demonstrate how the fractal deformation technique 
produces attractive results by showing various examples.
