Hello,
I'm looking to use ChBodyEasyClusterOfSpheres
<https://api.projectchrono.org/classchrono_1_1_ch_body_easy_cluster_of_spheres.html>to
create a simplified collider for a larger simulation I'm working on. It
seems I can pass it a vector of vectors of points that the spheres are
centered on, so that's what I tried to do. SphereCenters is an Nx3 numpy
array. Based on my read of the documentation and the errors I'm getting, I
am passing the right data types, but evidently I'm missing something, as it
still isn't working.
[setup code, all of this has been working]...
mesh_for_collision = chrono.ChBodyEasyClusterOfSpheres(
chrono.ChVector3d(chrono.ChVector3d(*sphereCenter) for sphereCenter in
sphereCenters),
vrad,
1.0,
False,
True)
torus_mesh.AddCollisionShape(mesh_for_collision)
torus_mesh.EnableCollision(True)
sys.Add(torus_mesh)
[then all the chronoirr code for visualization]
This still raises the error:
Traceback (most recent call last):

TypeError: Wrong number or type of arguments for overloaded function
'new_ChVector3d'.
Possible C/C++ prototypes are:
chrono::ChVector3< double >::ChVector3()
chrono::ChVector3< double >::ChVector3(double,double,double)
chrono::ChVector3< double >::ChVector3(double)
chrono::ChVector3< double >::ChVector3(chrono::ChVector3< double >
const &)
Any thoughts or insight would be greatly appreciated!
