Is there a stress nephogram in SOFA？

Is there a stress nephogram in SOFA？like the following picture:

Hi @Changjing-Liu

This depends on the ForceField yo are using and how the draw options/method are implemented.
Which one are you using?

Else we are thinking about proposing such nephogram through the Caribou plugin, aiming at a modular approach for FEM continuum mechanics. To be continued.

Hey @Changjing-Liu

For the TetrahedronHyperelasticityFEMForceField, this is indeed not implemented.
This could be done by updating the code (especially the draw function) as it is done in the TetrahedronFEMForceField

[ChangjingLiu]

Thank you so much for your speedy reply @hugtalbot
For the TetrahedronFEMForceField, where can I find the examples of draw function?

[hugtalbot]

Yes @Changjing-Liu
As I said, in the code TetrahedronFEMForceField.inl. Hope this helps

[ChangjingLiu]

Whoa, looks like I could try and finish the draw function of the TetrahedronHyperelasticityFEMForceField and submit a PR for it!
