Python code to find points/nodes values

1

Can you please tell how to get the vertices/nodes/points values from the mesh loaded using shapeworks? In below screenshot I can get the number of particles but how to get the values of particles?

You can use points() and faces()

>>> mesh.points()
array([[-103.06400299, -251.03999329,   41.98860168],
       [-102.5       , -251.11300659,   41.96179962],
       [-102.        , -251.09199524,   41.96450043],
       ...,
       [ -91.        , -238.        ,  151.08700562],
       [ -90.5       , -238.        ,  151.09599304],
       [ -90.        , -238.        ,  151.09100342]])

>>> mesh.faces()
array([[    4,     5,     0],
       [    1,     0,     5],
       [    5,     6,     1],
       ...,
       [75810, 75809, 80993],
       [80993, 80994, 75810],
       [75811, 75810, 80994]], dtype=int32)

You can explore the class using dir():

>>> import shapeworks as sw
>>> dir(sw.Mesh)
