[SOLVED] How can I get the local frames in TetrahedralCorotationalFEMForceField?

[Wong]

Hello everyone,

As some papers of Sofa presented, each tetrahedral element in TetrahedralCorotationalFEMForceField does have a local frame within it. And I want to use these local frames to do a mapping. So how can I obtain these local frames?

Hi @outtt

I have really no idea what you are talking about when you mention these “frames”.
Can you explain a bit please?

Hello @hugo,
I think this is the feature of the component in Sofa. It is no reason that you have no impression about this. The paper(figure 2) mentions about these local frames and you can know about it by reading this paper.

Hi Wong,

I saw the paper, but I am not sure whether I understand your question very well, I dont have so much experience, but you are looking for the local frames, for instance in the two attached figures below shows the this a simulation of the three layered beams and a point mapped to it. Could you please elaborate more whether these local frames you want to display them, or you want to know their location. I will do my best to help as much as I can.

Hello @meldiwiny,

Yes. It is just the kind of scene I am looking for, as the figures shown above. I want to map the beams to the local frames. How can I implement it?

The visualization of the local frames is not necessary, but it would be fine if they do.

Hello @meldiwiny,
Have you found the local frames?
I am eager to use them and waiting for your good news daily.

Hello @meldiwiny,

Thank you.

This topic can be ignored. I have solved the problem.

Nice to hear Wong,

Could you let us know how you solved your issue?
I close also this topic.
