An online garment model reconstruction method is proposed using the axial deformation to simulate the various garment models to display the wearing effect under different sizes. The garment model is classified into three categories according to the structural features. The main sections and key points are determined based on the existing dimensional features. Inverse operation and radial weight are used in the garment deformation. Texture mapping is applied to the model reconstruction result to obtain a new model with clothing patterns. An online system is developed and garment models with multiple scales are applied to adapt to various devices. The reconstruction results are compared and analyzed, which proves that the method proposed can realize real-time 3D reconstruction of garment models with the changing sizes on the web page.

As the EMUs (Electrical Multiple Unit) light frame structure, combined of many complex surfaces, building its geometric model directly is a big challenge. Reverse Engineering Technology is adopted to make the light frame redesign. Considering the characteristics of the frame surface with big curvature changed, irregular contours of structural features and IGES based model, authors proposed the model reconstruction method, by using independent geometric module in Pro/E. Firstly, establish base planes from IGES file, then duplicate light frame surface from IGES file to generate a set of intersection curves with the base planes and surface duplicated above as mixed guide curves. After that, curvature analysis technique is presented for intersection curves precision check. And finally, the 3D model is reconstructed by boundary blend technology. The original data imported can be removed from this model in order to support parts redesign as well as their manufacturability analysis. Research outcomes above offer an efficient innovation solution for surface reconstruction with curvature changed dramatically and IGES based model as well.

AbstractA geometric mapping establishes a correspondence between two domains. Since no real object has zero or negative volume, such a mapping is required to be inversion-free. Computing inversion-free mappings is a fundamental task in numerous computer graphics and geometric processing applications, such as deformation, texture mapping, mesh generation, and others. This task is usually formulated as a non-convex, nonlinear, constrained optimization problem. Various methods have been developed to solve this optimization problem. As well as being inversion-free, different applications have various further requirements. We expand the discussion in two directions to (i) problems imposing specific constraints and (ii) combinatorial problems. This report provides a systematic overview of inversion-free mapping construction, a detailed discussion of the construction methods, including their strengths and weaknesses, and a description of open problems in this research field.
