Research On Adaptive Skeleton-driven Deformation For Mesh Model

Digital geometry processing is an important branch of the research of Computer Graphics (CG), and it has been considerable developed in recent years in many areas. As an important part of that, mesh deformation has been widely used in the field of interactive games, television and entertainment, computer-aided design, industrial design, simulation, and more and more scholars have been focusing on it recently. Because the skeleton-based mesh deformation technology can be implemented in a simple and interactive way, it has been applied to a number of3D animation softwares such as3DMax, Maya.Based on the research on skeleton deformation methods, an interactive multi-skeleton-node deformation algorithm is proposed to overcome the shortcoming of one-bone driven and the predetermination, our algorithm can automatically adjust connected skeleton nodes; it thus implements the intuitive and adaptive local deformation of mesh model. Our method effectively combines the fundamental theories in computer graphics, computational geometry.The main content of this article includes:1The introduction of this article’s background and significance, the summary of related work on skeleton-driven deformation and the topology-based skeleton extraction algorithm used in this paper.2The skeleton nodes are approximated into a Bezier curve. With the interaction of skeleton node, the algorithm can automatically adjust connected skeleton nodes.3The local area of the surface vertexes corresponding to the skeleton has been re-bounded to enhance the control of the skeletons on the model in order to achieve more smoothing model deformation effect;4The weight of local model surface vertexes and their corresponding skeleton are calculated to make the mesh model deformation more smooth and natural.
