I’d give the reply above a thumbs up, if I could. ;D

Hi past @scheikl ,
you have to create the interactiveCamera at the root node to get the correct behavior.

Maybe @hugo can elaborate as to why that is. 😀

Hi!
I have a related problem.
I am able to control the internal data of an interactiveCamera, but it does nothing to the view itself, even though I made sure I am using the OpenGL view.

You can find a video of the behavior here: https://cloud.ipr.kit.edu/s/y2tjFW2Za4CX5p2

The code to set the pose is


def move_cam(camera, pose: Tuple[float,…[Read more]

Hi @andrija987,
sorry for the late reply, and that I could not help you solve the problem. 🙁

I am looking forward to the new issue, maybe we can approach that from another angle.

Cheers,
Paul

Hi @hugo ,
thanks for the follow-up! 🙂

Yes and no.
I would like tho get a measure of how much overlap is between two volumetric meshes.
I guess that should happen outside of the collision pipeline.
For example a small ball inside (at the center) of a large ball would not stand in collision with the larger ball.
So I am looking for something…[Read more]

Hi @twxu ,
sadly I am not familiar with the underlying code, but I guess there is some Matrix inversion involved which would make the computation scale roughly cubic.

I did not have the chance to work with cavity inside meshes yet.
Maybe someone from the SoftRobots Plugin (for example @@sescaida) could give you more hints on that?

You are very…[Read more]

Hi @twxu,
the computation time increases with your model size.

Are your models maybe a bit too large?
The Liver of the demo scene examples/demos/liver.scn, for example, has 181 points.

Cheers,
Paul

Hi @twxu,
oh, yes you are absolutely right.
You can generate that by setting recompute to true.

<PrecomputedConstraintCorrection recompute="true" />

Cheers,
Paul

Hi @twxu,
LinearSolverConstraintCorrection is actually a pretty expansive computation, as it solves the linear system at each time step anew.

Could you try the adapted scene as follows?

<root node>
<FreeMotionAnimationLoop />
<GenericConstraintSolver />
<DefaultPipeline />
<BruteForceDetection name=”N2″ />…[Read more]

Hi @andrija987,
I actually don’t know how I would approach that with two deformable bodies…

Maybe you could try to adapt the code in the actuated arm of the SoftRobots Plugin.

Personally I would try to take that code and add the deformable…[Read more]

Hi @andrija987,
no worries. 🙂

The beam part should not be necessary.
As long as you have some Rigid3 objects it should work fine.
I can highly recommend the Tutorials in the SoftRobots Plugin.
For ArticulatedSystemMapping this one should be quite…[Read more]

Hi @sukhraj,
happy new year!

Finding colliding elements between two specific collision models can be achieved with a ContactListener object: https://github.com/sofa-framework/sofa/blob/master/SofaKernel/modules/SofaBaseCollision/src/SofaBaseCollision/ContactListener.h

You can add that to your Scene with

listener = scene_node.addObject(…[Read more]

Solved in https://github.com/sofa-framework/SofaPython3/pull/78 🙂

Hi @jnbrunet,
No worries!

Thanks, have a nice holiday! 🙂

Cheers,
Paul

Hi @jnbrunet,
sorry for the late reply!

Oh okay, that makes sense.

Would a scene with default meshes from sofa/share be okay?

Hey @hugo,
no, the topic is still unsolved. 🙁

If anyone has an idea how to solve/avoid this issue, I would be happy to try it out and report on the results.

Cheers,
Paul

Hi Peter,
sadly I don’t have access to a windows computer, so I can’t really help you more on this.

Cheers,
Paul

Hi Peter,
I just realized I not catch that you are working with the windows version of SOFA.
There should be a SofaPython.lib inside of lib.

Cheers,
Paul

Hi Peter,
the extension (py) not handled is usually caused by SOFA not finding the correct plugin to handle python files.

When starting SOFA (runSofa in /bin), go to Edit->Plugin Manager and make sure “SofaPython” is listed as a plugin. If that is not the case, click “Add” and and select libSofaPython.so from /lib.

Let me know if that fixes…[Read more]
