Now if I were to use pure VTK, I’d create a mapper, an actor and render everything to a window. # generate a vtkPolyData from the vtkImageData MyMesh.GetCellData().SetScalars(scalarsvtk) # myMesh.AllocateScalars(vtk.VTK_UNSIGNED_CHAR, 3) # set 3 scalars per cell # Not sure why the following line is not necessary (tested using VTK) # allocate the scalars to the vtkImageData object Scalarsvtk = numpy_to_vtk(scalarsnp, deep=1, array_type=vtk.VTK_UNSIGNED_CHAR) Scalarsnp = np.tile(blue, (myMesh.GetNumberOfCells(), 1)) # Create an image (this is a data object)īlue = np.array(, dtype=np.ubyte) import numpy as npįrom _support import numpy_to_vtkįrom vtk import vtkImageDataGeometryFilter # this isn't in paraview.vtk

Understanding data”, but it is never shown how to use use it directly. This type of object is mentioned in the ParaView Guide in “3. How does one create a simple 2D mesh plot using ParaView from a vtkImageData object.
