siconos.io.shape_collection.load_vtp_file(shape_ref)

Read a VTP shape from an HDF5 reference and return a loaded mesh.

Parameters:

shape_ref: h5py.Dataset

HDF5 dataset containing the VTP shape, stored as a string

returns:

mesh (SiconosMesh or SiconosConvexHull) – Loaded mesh object

class siconos.io.shape_collection.ShapeCollection(io, collision_margin=None, backend='bullet')

Bases: object

Instantiation of added contact shapes

Parameters:

• io (reference object. Either a MechanicsHdf5Runner) – or a file name (vtk file describing a mesh)

• collision_margin (tolerance for collision, defaults to 0.04)

• backend (chosen backend, defaults to bullet)
