提出了一种骨架驱动的弹性变形无网格仿真系统。在该系统中，我们提出了一种新的方法来计算节点旋转，同时应用类似的技术与刚度翘曲，以解决非线性大变形。在我们的方法中，所有节点的旋转评估从采样点的附加骨架通过构造和求解扩散偏微分方程。实验结果表明，该方法可以提高动力学的稳定性，避免静态变形编辑中繁琐的子步计算。此外，通过采用简化技术，可以模拟骨骼关节周围区域的合理变形结果，而无需用户交互。
A meshless simulation system is presented for elastic deformation driven by skeleton in this paper. In this system, we propose a new method for calculating node rotation while applying a similar technique with stiffness warping to tackle the nonlinear large deformation. In our method, all node rotations are evaluated from sampling points in attached skeleton by constructing and solving the diffusion partial differential equation. The experiments indicated that the method can enhance the stability of the dynamics and avoid fussy sub-step calculation in static deformation edition. Moreover, rational deformation results for the area around the skeleton joints can be simulated without user interaction by adopting the simplified technique.
