The Visualization Toolkit (VTK) is open source software for manipulating and displaying scientific data. It comes with state-of-the-art tools for 3D rendering, a suite of widgets for 3D interaction, and extensive 2D plotting capability.
VTK is part of Kitware’s collection of supported platforms for software development. The platform is used worldwide in commercial applications, as well as in research and development.

New Features:
Annotation:
boom: New `vtkPolarAxesActor2D` avaialble for drawing a polar axes overlay.

DataModel:
boom: New `vtkImplicitArray` template class brings memory efficiency to vtk data array
applications. Author's note (9.4/add-vtkImplicitArrays.md).
The new `vtkAnnulus` implicit function represents an infinite annulus (two co-axial cylinders).
Author's note (9.4/annulus-implicit-widget.md).
boom: VTK now supports higher order Galerkin cells via a new data object `vtkCellGrid`. Author's
note (9.4/cell-grid-changes.md).
cell-grid-non-isoparametric (imgs/9.4/cell-grid-non-isoparametric.png).
ExecutionModel:
New information keys added to allow filters to execute without any prior temporal access for
in-situ visualization. Author's note (9.4/no-prior-temporal-access.md).
Filters:
New `vtkAppendPartitionedDataSetCollection` class to append multiple partitioned dataset
collections into a single partioned dataset collection. Author's note (9.4/add-append-PDC.md).
New `vtkCriticalTime` filter to generate time step values based on user-speci
