Research on Virtual Human Mesh Deformation Algorithm Based on Radial Basis Function

针对影视和游戏行业中的虚拟角色模型的定制和网格变形编辑问题,提出了一种径向基函数的虚拟人体角色网格变形的算法。算法通过增加一定数量的空间离散控制点,快速改变虚拟人体模型的局部形态,从而实现了虚拟角色模型的定制和网格变形编辑。借助这一算法,开发了虚拟角色快速制作原型系统。实验表明,算法和执行流程可以快速批量生产外形各异的虚拟人物角色,并用于具体项目需求中。整个生产过程可以完全通过程序控制完成,也可以引入一定的交互式操作,具有很高的灵活性和稳定性。

This paper presents a mesh deformation algorithm based on radial basis function(RBF) for virtual hu-man characters of virtual character models in the film and game industries. The algorithm can be used for rapidlymodifying models by adding a certain number of discrete control points. With this algorithm, we have developed arapid prototype system for virtual character creation. Experiments have shown that virtual character characters of var-ying shapes can be rapidly produced and used for various project requirements. The production process can be fullycontrolled by the program, or by a certain amount of interactive operations, which provides a high degree of flexibilityand stability.
