t-FFD: free-form deformation by using triangular mesh

Soft tissue deformation based on tensegric modeling is proposed. This modeling is especially applicable for human females to reform/alter their body shape using tailor-made undergarments. When a digitized mesh data of customer's body surface is provided, a tensegric model is generated, simulating a physically-based deformation of the body shape. The tensegric model is based on a sparse triangular mesh, which approximates body shape. The constraints on the deformation are the constant volume of the model, and the length of specific lines lying on the model's surface, which correlates directly with the size of the undergarments. After the tensegric model is deformed by those constraints, the deformed body shape is calculated by t-FFD (Free Form Deformation by using Triangular mesh). This process operates in real-time in a standard PC environment, and aids customers appreciate the physical effects of the shaping undergarment.
