Modification of forcefields’ positions

[ARN]

Hi
How can I change the center of forcefields at runtime using C++?

[Hugo]

Dear @arnr

Could you detail what you mean by changing the center of a forcefield?
Are you talking about a specific forcefield?

Best wishes,

Hugo

Dear @Hugo
Hi!
I want to get the list of all forcefields in the scene and move them in runtime.
if it’s possible please give me an example for the Spherical ForceField.

Best regards.

Dear @arnr

ForceFields in SOFA corresponds to internal or external forces applied on bodies.

I think what you mean would be to modify the SphereForceField so that the center of force would be evolving among time. Is this correct?

If so, it would look like:

// definition of the sphereFF in the scene
typename sofa::component::forcefield::SphereForceField<Vec3d> SphereFF = New<sofa::component::forcefield::SphereForceField>();
m_root->addObject(SphereFF);

...

for( interation loop)
{
    // move at each time step the SphereFF
    SphereFF->setSphere(const Coord& center, Real radius);
}

I hope it helps.
Best,

Hugo

PS: are you working at Kyungpook NUT ?
