Hi community and Alessandro
I'm trying to update meshlab from 2023.12 to 2025.7 and i have an the call to meshing_decimation_quadric_edge_collapse?
It does not exist anymore or maybe has been renamed?
Here is the piece of code:


 ms = ml.MeshSet()
    ms.add_mesh(ml.Mesh(mesh.vertices, mesh.faces))

    ms.compute_scalar_by_discrete_curvature_per_vertex()
    m = ms.current_mesh()
    curvature_values = m.vertex_scalar_array()
    quality_weights = np.ones_like(curvature_values)
    quality_weights[curvature_values < 0] = boundary_preservation_factor
    m.vertex_scalar_array()[:] = quality_weights

    target_faces = max(
        10, int(candidate_target_count * (len(mesh.faces) / len(mesh.vertices)))
    )

    ms.meshing_decimation_quadric_edge_collapse(
        targetfacenum=target_faces,
        qualityweight=True,
        preserveboundary=True,
        boundaryweight=1.5,
    )

And here the error at runtime


  ms.meshing_decimation_quadric_edge_collapse(
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'pymeshlab.pmeshlab.MeshSet' object has no attribute 'meshing_decimation_quadric_edge_collapse'
