Physical Simulation:Mass-spring systems 质点弹簧系统是一种经典的物理模型,简单方便,但稳定的求解器还是需要使用比较复杂的隐式欧拉积分方法,利用雅可比迭代法或者共轭梯度法求解大规模的线性方程组来求解速度矢量。这篇博客内容是学习了胡渊鸣大佬开的课程的笔记。 质点弹簧系统是一种拉格朗日视角的物理模拟,把...
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...
网格弹簧质点系统模拟(Spring-Mass System by Euler Integration) 弹簧质点模型是利用牛顿运动定律来模拟物体变形的方法。如下图所示,该模型是一个由m×n个虚拟质点组成的网格,质点之间用无质量的、自然长度不为零的弹簧连接。其连接关系有以下三种: 1.连接质点[i, j]与[i+1,j],[i, j]与[i,j+1]的弹簧,...

3. Specify the system parameters: Define the parameters of the system, including the mass, damping coefficient, and spring constant. Since you mentioned that the mass is unknown and will be iteratively tested, you can set an initial value for the mass and update it during the simulation based...
Mass Spring System(弹簧系统)
质点弹簧系统在模拟布料时经常使用,但显式方法不稳定,容易算炸。隐式方法通常计算量大。因此可以使用一种快速隐式方法,利用最小二乘法最小化能能量,来比较快比较稳定地来解算质点弹簧系统。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。

In this paper, a mass-spring system is used to predict the draping behavior of woven fabrics. The material properties important to fabric draping are measured from the Kawabata system and the experimental data are incorporated into the simulation to calculate internal forces, based on which the ...
