vtu files, multiple fields

[fdeheeger]

very convenient to explore VTK files inside jupyter.

The example gallery is great but I cannot find a simple example of a direct show of a vtu file while picking the right scalar field to be presented on the mesh.
Any hints ?

Hi try for ex:

from vtkplotter import *

mesh = load(datadir+'pulley.vtu')

mesh.addPointScalars(mesh.coordinates()[:,0], 'my_x')
mesh.addPointScalars(mesh.coordinates()[:,1], 'my_y')
mesh.addPointScalars(mesh.coordinates()[:,2], 'my_z')

mesh.scalars('my_y') # or mesh.scalars(2)
printInfo(mesh)

show(mesh)

Inside jupyter:

(the actual printout format will be a bit different)

Thanks a lot for your help. printInfo does help a lot.
