position of the lower jaw and the second layer from above is the height of
eyes. Also, it is also possible to supply position information that in the
perimeter of these sections which vertex represents the left and right eye or
the mouth. (Figure 9). This way it becomes possible to supply general
information about a certain type of parts, and integrate the individual parts
data into a meaningful Shape of Fundamental Model.

Scanned Shape
It is possible to acquire very delicate but static shape data
consisting of several hundred thousands of polygons about the individual
objects with a three-dimensional scanner. We call this the “scanned shape”.
It is possible to reduce the number of polygons of the scanned shape and
apply textures on them and thus create a graphics model of arbitrary quality,
but the scanned shape being one kind of the sampled data, it does not have
any information about meaning. Also, as the individual sampled data is
not unified, applying “meaning” to it becomes relatively computation-
intensive, thus it is not quite viable. Therefore, if meaning-based data
representation and manipulation is required, then it is necessary to create
the so-called Shape of Individual Model we detail below.

Shape of Individual Model
On one hand, the Shape of Fundamental Model
reflects “meaning”, while on the other hand it represents the scanned
shape with approximated polygon data. In other words, the Shape of
Individual Model is a mediator that provides a link between the data sampled
