Abstract
The paper describes a method of assessing the similarity of digital mannequins by using parametric representation. It is the approach in which a computer mannequin model is created by means of the parametric design method before assessing the similarity of models. A wireframe is used for modeling complex surfaces. Firstly, a basic model is applied to a triangular mesh via section decomposition, symmetrization and polynomial approximation. Secondly, parameters are chosen from the anthropometric parameters and the dimensional parameters of the apparel industry standards for the parameterization of the basic model. Thirdly, the basic model is deformed in accordance with the change of the  prescribed parameters. The deformation method includes the following stages: building additional sections, deforming these additional sections according to the change of the prescribed parameters, shifting and linear approximation of the basic sections in compliance with the change of the additional ones. Finally, the deformation results are estimated by using five similarity characteristics of the deformed models and their virtual prototypes.
