Hi @Hugo,

Have you gotten back from holidays?

Wong

Sure, I will @ you on December 17.

Hello @hugo,

Just want to drag or block the artery/vessels and clip the aneurysm. So the level of accuracy should be fairly high.

Wong

Hello @hugo,

Just deform flexibly like the real one, from all directions and keep the performance in persisting contact. Because the vessels are located in the gap of the soft tissues.

Wong

Hello @hugo,

Where can I find the plugin using shell model?

Wong

Hello @yordan-kyosev

I think the situation is more complicated than you think. What I want to model is something like vessels. So you have to think on the case that the rope has branches.
As far as I can see, representation of beam is still nothing more than a strings of rigid bodies. It may cause low performance having masses of rigid frames and…[Read more]

Hello @epernod

By the way, now how are your TopologicalModifiers coming along in volumetric cutting? I think the topological change for tetra mesh at runtime could help deal with this problem.

Wong

Hello @epernod

Well, I have to say that I have ever tried to use SubsetTopology.
But the first problem is that using SubsetTopology would make the scene more complicated and inefficient. Secondly, the spring connecting the Hex and Tet mesh would result in abnormal behavior when the haptic feedback involves. And the constraint solving process…[Read more]

Hello @hugo

Do you mean you will talk about this case in the session?
After all I will be not be able to attend this session and I do not know if you will find a solution at last.
So I think I will try another method to solve this issue, such as remeshing techniques and will also at the same time wait your news after the session.

Hello @hugo

I did not couple the needle and the brain though. You saw such scene at the beginning just because the Geomagic plugin was not at work.

Well, what I want to achieve is to make the local deformation closer to reality as you can see in the picture of the realistic surgery in the attachment.

Did you see the two pictures in that…[Read more]

Hi @hugo

Do you have any progress?

Wong

Hello @hugo

Do you have any progress?

Wong

Hello @hugo

Could you give me a reply?

Wong

Hello @hugo

ROIBarycentricMapping does inherit from BarycentricMapping.
You can see the m_mapper there.

Hello @Hugo,

I use Sofa v19.06 and there is no any compile error.
And can you tell me how to make it an external plugin?

Wong

Hello @hugo

Can you give me a reply?

Wong

Hello @hugo

This is my example. I hope you can literately help me. The issue is described in ReadMe.txt so you should be make sure that you read it beforehand.

https://www.dropbox.com/s/epexah0rjj49zh0/problem.rar?dl=0

The version of Sofa is 19.06. You can use your own method to modify(refine) the tetrahedral mesh because if I provide it, it…[Read more]

Hello @hugo

Well, however this plugin is extraordinarily hard. I once raised this issue on the forum but the author of the plugin did not give an example about free contacts on some local area of a soft body. And this plugin is temporarily used for soft robots not for free contacts.

So if any relevant developers & authors do not have time to…[Read more]
