Hello everyone,
I am facing some issues when trying to create an instrument with more than two sections. In such a case, an erratic motion can be observed.
To reproduce the issus, one may start from the basic example _3instruments.scn_ and modify it the following way:
- I added a third section to the guidewire (I added line 37 to add a second straight section
``
- modified line 36 to maintain the same total straight length and the same number of visual and collision edges ``
- and added this section in line 40
``.
You can find here the complete modified scene:
```xml
```
I am using SOFA v23.12.0 and BeamAdapter v23.12.
Is there any additional line I should modify in order to add the third section? @epernod , @hugtalbot do you have any idea?
Thanks a lot for your help!
Hi,
thank you for the report and the scene. I have tested on my side and I also have an... helicopter motion.
I will work on it... hopefully this week, or next week.
