Hello @nickhockings,

Although I built it successfully but actually I want to report that there were some compile errors which occured in VS2015.

like in load_surface_meshes.cpp line 35
YAML::Node config = YAML::LoadFile(it->c_str());
should be change into
YAML::Node config = YAML::LoadFile(it->string());

And there are some other places using…[Read more]

Hello @hugo,

luckily, I tried to buid it and I succeeded! Only CGAL and Yaml-CCP should be built threre, other dependencies can be directly downloaded and used.

I would continue to test it if there are bugs there. But I think it is hard for me to read the code about CGAL and there is very few information and tutorials on the Internet about how…[Read more]

Hello @olivier-goury

Do you know about this？

Wong

Hello

I think you can take a look at this link to see if it is suitable for you.

Hello @hugo,

Can you tell me how to use MeshMatrixMass because there is no existing example.

I use RestShapeSpringsForceField because I do not want to make the fixed part so hard sometimes.

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.

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?
