本文为对Fast Simulation of Mass-Spring Systems的阅读笔记。本文并非翻译性质或公式推导性质的文章,文章的结构和内容与原论文有极大出入,甚至记号都不一致。内容以我个人的理解为主,不过只要我理解没有问题,那本文介绍的方法和原论文里的应该是一致的。 若有不正之处,烦请指正。 一、隐式欧拉法 从使用隐式欧拉法...
快速隐式质点弹簧的求解方法来源于论文"Fast Simulation of Mass-Spring Systems ",这也是projective dynamics中的一种。 本篇文章将介绍首先介绍快速隐式求解弹簧系统,然后介绍普通隐式求解质点弹簧系统。这两种方法我都使用python实现了一维二维三维,并且在unity中实现了cpu三维求解。其它值得一看的包括cholesky分解以及各...

Fast Mass-Spring System Simulator A C++ implementation of Fast Simulation of Mass-Spring Systems [1], rendered with OpenGL. The dynamic inverse procedure described in [2] was implemented to constrain spring deformations and prevent the "super-elastic" effect when using large time-steps. Dependencies...

The large-scale simulation of dynamical systems is critical in numerous scientific and engineering disciplines. However, traditional numerical solvers are limited by the choice of step sizes when estimating integration, resulting in a trade-off between accuracy and computational efficiency. To address this...

Interactive simulation of cloth has been an important research topic in computer graphics for many years. An interactive simulation demands efficient and unconditionally stable methods. In the beginning simple spring–mass systems in combination with explicit integration schemes were used in order to obtai...
