With the rapid advancement of 3D scanning technologies, high-fidelity geometric datasets of huge size have been acquired through hardware devices. A fundamental and challenging problem is how to build the best possible (surface and volume) mapping between different objects of arbitrarily complicated topological types. Inter-shape mapping, or more specifically, finding a low distorted correspondence between two given shapes is a very powerful enabling tool for various applications in digital entertainment, modeling and simulation, vision, medical imaging, and visualization, etc. We seek accurate and efficient solutions to this fundamental and important problem. We have articulated and developed a general and powerful shape mapping paradigm for objects in different dimensions (from 1D curves, 2D surfaces, to 3D solid objects) with arbitrary topologies. Compared with existing shape mapping techniques, our work offers a better and integrated solution to the inter-object correspondence problem. We explore great potential of our mapping framework through various valuable applications such as shape matching, deformation analysis, animation morphing, information transfer, re-meshing, texture synthesis, physics-based modeling, and so on. Furthermore, we envision broader application scopes including scientific simulation, vision, content-driven information retrieval, digital medicine, virtual environments, etc.
