Abstract: A novel polygon model describing human body shape is developed. Firstly, a method of expressing an arbitrary point on a polygon mesh using the UV plane is proposed. An isomorphic feature of the model enables us to fit the polygon model to three-dimensional (3D) measurements by means of the least square method. Secondly, in order to optimise the model structure, vertices of the model are allocated to trunk shape based on multiple sets of 3D measurements of Japanese women. Finally, the experimental results show that the derived generic model consisting of 1,087 vertices can reconstruct the original shapes with the average error of 1.19 mm, sufficient for practical use.
