You’re very welcome! 🙂

Thanks, you too!

Hi @chiarasapo,
glad I could help!

I would suggest using a Sofa.Core.Controller to call the function on a specified event, such as AnimateEndEvent.
There is a nice example in the SofaPython3 repo.

Just delete all the functions that you do not need. 🙂
For example


class PrintContactController(Sofa.Core.Controller):

def __init__(self,…[Read more]

Hi @chiarasapo,
are you using SofaPython3 out-of-tree?

Also try removing the build folder to start clean.

What may also help is doing a separate install step after building.
cmake --install <sofa target folder>/external_directories/sofapython3/bindings

Cheers,
Paul

Hi @chiarasapo,
as you can see in the bindings for ContactListener, the method getNumberOfContacts is commented out. Could you try uncommenting and recompile it?

Cheers,
Paul

Hi @newbie,
you might want to check out SofaPython3.

There is a binding for the ContactListener, so you can create a ContactListener object with
listener = contactlistener.addObject(
“ContactListener”,
collisionModel1=”@/finger/collisionFinger/triangle”,
collisionModel2=”@/skin/SkinCollision/point”,
)

N…[Read more]

Hi @newbie,
I just tested the scene, and the following works fine for me:


contactlistener.addObject(
"ContactListener",
collisionModel1="@/finger/collisionFinger/triangle",
collisionModel2="@/skin/SkinCollision/point",
)


Cheers,
Paul

Hi @newbie,
I totally missed the fact, that you gave the models a specific name, sorry. 😀
Try replacing the type of Object (TriangleCollisionModel) with the name you gave it (triangle). Same for the PointCollisionModel.

Cheers,
Paul

Hi @newbie,
ah the ContactListener is not in the root node, so your path misses going up one step in the tree.
You could try

contactlistener.createObject('ContactListener', collisionModel1 = '@../skin.SkinCollision.TriangleCollisionModel', collisionModel2 = '@../finger.collisionFinger.PointCollisionModel')


Cheers,
Paul

Hi @newbie,
by specifying collisionModel1 = '@skin.SkinCollision' you are not pointing to an actual collision model, but to a SofaNode that contains multiple collision models.

Try changing that to
contactlistener.createObject('ContactListener', collisionModel1 = '@skin.SkinCollision.TriangleCollisionModel', collisionModel2 =…[Read more]

Hi @newbie,
sadly I started using Sofa with SofaPython3 directly so I’ve never really used SofaPython2.

Is there an error message you could post?

Is the relative path to SkinCollision and collisionFinger correct?

Cheers,
Paul

Hi @newbie,
please note, that there is a difference between SofaPython and the Plugin SofaPython3.

If you are using SofaPython3, you can add a ContactListener with

listener = scene_node.addObject(
"ContactListener",…[Read more]

Hi Sergio,
you’re welcome!
Glad that I could help. 🙂

Hi Sergio,
I think PartialFixedConstraint is what you are looking for.

There is an example at https://github.com/sofa-framework/sofa/blob/master/examples/Components/constraint/PartialFixedConstraint.scn

<PartialFixedConstraint name="partialFixedConstraint" indices="3 39 64" fixedDirections="0 1 1" />

Cheers,

Hi Simit,
you can pass additional arguments to the runSofa binary.
runSofa --help gives you a detailed list of possible options.

Directly running a simulation can be done with
./runSofa -a 1 /path/to/scene/file

Cheers,
Paul

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. 😀

Cheers,
Paul

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]
