Abstract

Vertex Block Descent (VBD) is a fast and robust method for the real-time simulation of deformable objects using the finite element method. Originally, the method was designed for the popular linear tetrahedral elements. However, these elements have low accuracy and introduce locking artifacts. In this context, we propose an extension of VBD to: (i) support any isoparametric elements and shape function orders; (ii) improve its performance even for high-order elements; and (iii) enhance convergence through the use of sub-stepping. Overall, using other types of elements enables more accurate results while maintaining a computational cost comparable to linear tetrahedra.

进一步使用顶点块下降

顶点块下降法（VBD）是一种快速、鲁棒的可变形物体有限元实时仿真方法。最初，该方法是针对流行的线性四面体单元设计的。然而，这些元素的精度较低，并引入了锁定工件。在这种情况下，我们提出了VBD的扩展：(i)支持任何等参元素和形状函数顺序；（ii）提高其性能，即使是高阶元件；(3)通过使用子步进来增强收敛性。总的来说，使用其他类型的元素可以获得更准确的结果，同时保持与线性四面体相当的计算成本。

期刊介绍： With the advent of very powerful PCs and high-end graphics cards, there has been an incredible development in Virtual Worlds, real-time computer animation and simulation, games. But at the same time, new and cheaper Virtual Reality devices have appeared allowing an interaction with these real-time Virtual Worlds and even with real worlds through Augmented Reality. Three-dimensional characters, especially Virtual Humans are now of an exceptional quality, which allows to use them in the movie industry. But this is only a beginning, as with the development of Artificial Intelligence and Agent technology, these characters will become more and more autonomous and even intelligent. They will inhabit the Virtual Worlds in a Virtual Life together with animals and plants.
