directly from the real world and the model for database construction. The
Shape of Individual Model has the shape of the individual objects and
because it is created with relatively few polygons, a virtual CG space can
be constructed with the Shapes of Individual Model, in other words, a
scene database. As it is possible to measure the “unity” among the
individual objects, it is particularly useful and effective in data retrieval
and comparative evaluations. As a result, the “meaning” of each polygon
is common in the all shapes of Indivisual Objects. For example, No.32
polygon always means the position of the left eye and No.66 polygon means
the top of nose and so on. This is very important in the retrieving by using
graphic information.

The acquisition and evaluation of the Shape of Individual Model
Based on the aforementioned theory, we created an experimental Shape of
Individual Model acquisition system and evaluated it.

Acquisition of the scanned shape
To acquire the scanned shape data, we used a non-contact type three-
dimensional scanner made by Cyberware (COLOR 3D DIGITIZER
