Taken into consideration this practical application , a novel method for parameterized mannequin modeling was proposed . Feature parameters are determined according to anthropometry . Both template and result models are described in terms of polygonal meshes. Low level geometry handling is based on axial deformation technique in computer graphics. Additionally , Radial deformation weight curves also have been introduced to improve the flexibility of modification . The remarkable advantages of this method are the simplicity of operating , the intuition of input and the quick speed of modeling. The method can be effectively applied to 3D garment simulation environment in need of individua
