Examples of use of vtkInterface for Scientific Visualization in Python using VTK.

vtkinterface_example.py

import vtkInterface
from vtkInterface import examples

# Load Grid
grid = vtkInterface.UnstructuredGrid(examples.hexbeamfile)

# scalar demo
plobj = vtkInterface.PlotClass()
plobj.AddMesh(grid, scalars=grid.points[:, 2], colormap='viridis')
plobj.AddScalarBar()
plobj.Plot()

vtkinterface_export_file.py

import numpy as np
import vtkInterface

x = np.arange(-10, 10, 0.25)
y = np.arange(-10, 10, 0.25)
z = 0
x, y, z = np.meshgrid(x, y, z)

data = np.column_stack((x.flatten(), y.flatten(), x.flatten()))
grid = vtkInterface.StructuredGrid(x, y, z)

# Add data
grid.AddPointScalars(data, "data")
grid.Write("test.vts")
