### paper Interactive Simulation of Elastic Deformable Materials

Hi has any one readed the paper "Interactive Simulation of Elastic Deformable Materials" by martin.servin In chapter 2.4 they propose a new time step method but I can not deduce the formula a*lambada formulateinpaper.png this is my deduce mydeduce.jpg Note the term "1/2 * deltat + B" is differently ...

### Re: Is collision constraint proposed in PBD paper correct?

I have the same question, how to make a robust softbody surface-softbody surface collision algo,and make it suitable for use in the PBD

### Re: Capsule separating axis

Actually in my code I find Axis as 1. triangle face normal, 2.Triangle edge-capsule edge , 3.triangle point - capsule edge 4.trignale point - capsule edge point 3 and 4 will have totally 2+2*3 axis but they can be simplified to 3 axis test .in my code i first find the cloest point between first tria...

clauchiorean:

Thanks a lot for the information , By the way do you know how current games couple the IK system with the artists-maded animation ?

### Re: Opensource inverse kinematics library

Hi clauchiorean:
I am very interseting about the implementation of the project ,what method do you use in the IK solution, I only know the simple cylic coordinate descendt but seems not enough could you refer me the method use in your project?

### Re: New research on real-time deformable body dynamics (FEM)

Hi Dirk： I read the paper <<A nonsmooth nonlinear conjugate gradient method for interactive contact force problems >> But there seems some problem in the paper . As they say r = (H − I)Lamda+h can be interpreted as the gradient of a non-smooth nonlinear quasi-quadratic function f(Lambda) ≡ 1/2|| r||...

### Re: New research on real-time deformable body dynamics (FEM)

XperienS: Thanks alot for you reply,that's the data I need, Actually I am more intersting about your new CG LCP sover, so you mean you solve rigid body and sift body all use your new solver? Or you use traditional PGS solver for rigid body and use your new solver for rigid-soft constraint(contact et...

### Re: New research on real-time deformable body dynamics (FEM)

That's great ,Look forward to see your paper,but also I am a little intersted to know the speed efficiency and memory need when solve the system

### Re: [Help] Need method to fill a Surface mesh with nodes

the paper<<Tetrahedral Mesh Generation for Deformable Bodies>>
describle the volume mesh generate . but it based on tetrahedron ,may be you can change the method to cube?hope this will help
