Fit zone modeling
Interactive modeling of fit zone from 3D body data
A garment can be divided into two zones to facilitate the 3D pattern generation. One is
the fit zone, and the other is the fashion zone. The fit zone of a garment is in direct
contact with the body surface and is responsible for the comfort of a garment that it
must be designed to correctly reflect the shape of underlying body. In our previous
research, the fit zone was modeled automatically from the body scan data, however, it
was somewhat difficult to get a desirable shape of the fit zone with this method
especially for slacks (Kim and Park, 2004; Kim and Kang, 2002). In this study, a fit zone
was modeled by capturing and reconstructing the quadrilateral gird structure marked
on the surface of a mannequin using a multi-joint coordinate measurement system as
shown in Figure 1.
The surface model of a fit zone was constructed as a B-Spline surface taking the
measured grid points as their control points as shown in Figure 2. The shape of fit zone
was then refined to have a smooth shape by adjusting the position of each control point
manually. Zebra striping technique was applied to verify the smoothness of the surface
visually as shown in Figure 2.
Some examples of the fit zones prepared by this method are shown in Figure 3.
