Dear Rus,

We had many issues with Sensable.
With the Geomagic plugin, make sure to use the GeomagicDriver (and not Omni Driver anymore). See the example in applications/plugins/Geomagic/scenes/Geomagic-Demo.scn

<RequiredPlugin pluginName="Geomagic"/>
<GeomagicDriver name="GeomagicDevice" deviceName="Default Device" scale="1" drawDeviceFrame="1" positionBase="0 0 0" orientationBase="0 0 0 1"  />

Cheers,

Hugo

Dear Mingling,

I succeeded to get the right rotation for both by writing:

...
<Node name="Tooth" >
        <Node name="VisualModel" >
            <OglModel name="ToothVisualModel" fileMesh="Demos/Dentistry/data/mesh/skull_and_teeth.obj" color="white" rotation="0 180 90"/> 
        </Node>
        <Node name="CollisionModel" >
            <MeshObjLoader filename="Demos/Dentistry/data/mesh/skull_and_teeth_coarse.obj"  name="loader" rotation="0 180 90"/>
...

Let me know if it works.
About carving, please look at the links I just sent you.

Best,

Hugo

Dear Nathol,

I never saw an error on this m_componentstate (which is a parameter in a class).
Do you need to compile SOFA yourself? You don’t want to use binaries of SOFA?

Moreover, VS2012 is not supported anymore.
We are now moving at least on VS2013 and VS2015 (see the dashboard). This might be the cause of your issue.

Cheers,

Hugo

Hi Mingming,

Thank you for choosing and experimenting SOFA!

We would need more detail to answer you: what scene are you talking about?
on which object did you apply the rotation ?

For topological changes, please see:

• https://www.sofa-framework.org/community/forum/topic/how-to-incise-3d-object/

Dear Lujain,

Thank you for choosing SOFA!
As you might have noticed, we already have a basic liver simulation example in examples/Demos/liver.scn. You can use this model for your research of course.

However, your question “which component should I use” is too vague. In SOFA, you need to know what simulation you want to achieve. This means that you need to know what spatial an time integration you want to use. Then, I could answer your question.

Cheers,

Hugo

Dear Ben,

The attached ensures that forces are exchanged and added between the constraint points with the same DOF (Vec3d with Vec3d). I guess it isn’t working since you are trying to relate Vec3d and Rigid.

I guess a solution would be to have a rigid object, one Vec3d mechanical (with one single DOF) mapped together with a RigidMapping. And finally, a AttachContraint between your 1-DOF MechanicalObject and your deformable object.

I hope I’m clear, it’s late!
Cheers,

Hugo

Dear Rob,

Sorry for the delay.
Indeed, SOFA would be a good choice I think. A company in the SOFA community (Anatoscope) has expertise in this field. I would advise to contact them.

Best,

Hugo

Ciao Albert,

We are not that much writing scene in Cpp now, we all rather use Python.
But, to answer your question, we you have your simulation:

sofa::simulation::Node::SPtr childNode = rootNode->getChild("name_of_the_child_node")

OglModel< ExtVec3f >* my_OglModel = childNode->get< OglModel < ExtVec3f > >();
my_OglModel->translation.setValue(set_here_a_Vec3_translation);

I am writing from memory, so take is as a hint,
my two cents.

Hi Luigi,

What you want to do is to load a mesh ?
The cuboid is generated in the .scn file by :

<Node name="Visu">
                    <OglModel name="Visual" position="-1 -0.5 -0.5 -1 0.5 -0.5 -1 0.5 0.5 -1 -0.5 0.5 1 -0.5 -0.5 1 0.5 -0.5 1 0.5 0.5 1 -0.5 0.5 -1 -0.5 -0.5 -1 0.5 -0.5 -1 0.5 0.5 -1 -0.5 0.5 1 -0.5 -0.5 1 0.5 -0.5 1 0.5 0.5 1 -0.5 0.5 -1 -0.5 -0.5 -1 0.5 -0.5 -1 0.5 0.5 -1 -0.5 0.5 1 -0.5 -0.5 1 0.5 -0.5 1 0.5 0.5 1 -0.5 0.5 -1 -0.5 -0.5 -1 0.5 -0.5 -1 0.5 0.5 -1 -0.5 0.5 1 -0.5 -0.5 1 0.5 -0.5 1 0.5 0.5 1 -0.5 0.5" triangles="3 1 0 3 2 1 3 6 2 3 7 6 7 5 6 7 4 5 4 1 5 4 0 1 5 1 2 2 6 5 4 7 3 4 3 0 11 9 8 11 10 9 11 14 10 11 15 14 15 13 14 15 12 13 12 9 13 12 8 9 13 9 10 10 14 13 12 15 11 12 11 8 19 17 16 19 18 17 19 22 18 19 23 22 23 21 22 23 20 21 20 17 21 20 16 17 21 17 18 18 22 21 20 23 19 20 19 16 27 25 24 27 26 25 27 30 26 27 31 30 31 29 30 31 28 29 28 25 29 28 24 25 29 25 26 26 30 29 28 31 27 28 27 24" />
                    <RigidMapping template="Rigid3d,ExtVec3f" rigidIndexPerPoint="0 8 8 8 8" input="@.." output="@Visual" />
                </Node>

To replace the cuboid, all you need to do is to set the mesh you want to visualize in the field filename of the OglModel:

    <OglModel name="VisualModel" fileMesh="path_to/my_mesh.obj"/>

and taking care of the rigidIndexPerPoint parameter in the RigidMapping.
Hope this helps,

Cheers,

Hi Sen,

You can use the TopologicalChangeProcessor component as an example. Many example scenes illustrate it in example/Components/topology/TopologyModifers/.

Best regards,

Hugo

[Hugo]

Hi Ruslan,

Could you let us know about the SOFA version you are using ?
Is it the master branch ? up-to-date ?

Isn’t it just the creation of your component that would require a new to allow dynamic memory allocation? I haven’t been writing a scene in Cpp for a long time, I’d rather use Python.

By the way, there is now a Geomagic plugin to interface with the haptic devices from Geomagic. You should have a look at it: https://www.sofa-framework.org/about/news/new-geomagic-plugin/

Hope this helps,
Cheers,

Hugo

Thank you very much for your input Mermail !
Nice work.

Hi Binesh,

There is unfortunately no doc on solvers yet. We are working (slowly) on it.
What kind of solvers would you intend to develop?
Some topics on the forum discussed shortly the solvers, but it remains very light:

• about an optimization integrator
• about forcefields collisions and integration

Cheers,

Hugo

[Hugo]

Hi Mermail,

Could you shortly detail your solution?
Thanks for sharing.

Best,

Hugo

[Hugo]

Dear Mao,

Indeed, the Modeler is not provided in the binaries.
To use it, you need to use and compile the sources.
The Modeler is not sufficiently maintained to be provided in the binaries. We are working on distributing a new Tutorial application with the binaries.
Would this suit your needs?

Cheers,

Hugo

[Hugo]

Thank you for sharing Jaime!

[Hugo]

Dear Benoit,

I am very sorry you did not get an answer yet.
We are not big users of Novint Falcon in Strasbourg.

Hopefully, some other SOFA developers may give some feedback about it!
Anyone ?

Best,

Hugo

[Hugo]

Wahou ! Thanks @epernod !
We did not even know it !

https://cmake.org

Special thanks to Kitware for their article!

[Hugo]

Hervé,

Can you share with us an example of your scene so that I can try a workaround?
Cheers,

Hugo

[Hugo]

Hi Jason,

In this case, I would rather use :

• MeshVTKLoader
• and a VTKExporter

Could you try this ?

Note: ReadState is usually used to “replay” a previous simulation whose positions where saved with a WriteState.
