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...
Cloth Simulation: Implemented a Mass-Spring System algorithm, inspired by the"Fast Simulation of Mass-Spring Systems"paper, for fast and accurate simulation of cloth physics. Integrated OpenMP for efficient parallelization of cloth physics computations, significantly improving performance. ...

This article presents a new method to model fast volume preservation of a mass-spring system to achieve a realistic and efficient deformable object animation, without using internal volumetric meshing. With this method the simulated behavior is comparable to a finite-element-method-based model at a...
Fast Volume Preservaiton for a Mass-Spring SystemHong, MinJung, SunhwaChoi, MinhyungWelch, Samuel W. J
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...
