[ERROR] [TriangleSetGeometryAlgorithms(GeomAlgo)] Edges don't intersect themself. Tearing mesh crashes on Ubuntu but works on windows

[kashyappiyush1998]

Hello,
I am trying to run tearing plugin both version 23.06 and master branch with sofa 23.06. I am sharing my scene file and mesh. The code crashes on ubuntu Ubuntu 20.04.6 LTS with error

Hi @kashyappiyush1998

Thanks for reporting the issue.
Does this remind you a spotted issue @epernod @rmolazem?

[rmolazem]

Hi @kashyappiyush1998

Thanks for sharing the issue. To apply Tearing plugin (at master stage), we recommend using SOFA version 23.12.
Meanwhile, could you please provide the errors shown in the console, not only the crash log?

[kashyappiyush1998]

Hello @rmolazem,
Trying to build Tearing plugin main branch with sofa 23.12 fails with error

/home/piyush/Downloads/sofa-project-main/src/extras/Tearing/src/Tearing/TearingEngine.inl:32:10: fatal error: sofa/component/constraint/projective/FixedProjectiveConstraint.h: No such file or directory
   32 | #include <sofa/component/constraint/projective/FixedProjectiveConstraint.h>

This is because FixedProjectiveConstraint.h is from now master sofa or one being built at the moment towards sofa 24.06

So, I tested sofa latest branch that passed tests with tearing main. This throws different error

Hi, are you using the mouse to pull the tissue?

[kashyappiyush1998]

Yes I am using mouse in both windows and Linux.

[epernod]

Hi,

thank you for your report. Indeed, we have several issues at the moment in the plugin. Some work has been achieved earlier this year to fix the tearing behavior but the mouse support has not been addressed.
We will put that on our todo list but to do hesitate to open an issue to keep track of the issue.
We will work on the mouse interaction as soon as we can. Unfortunately we have limited budget to support this plugin and right now it is not in high priority. If you would like to speedup the work do not hesitate to sponsor us!

Thank you
Best regards
