			=== Package ===
			Most packages are available in the package install systems, e.g. on Ubuntu
			`vtk6`, `vtk6-examples`, `libvtk6.2`, `libvtk6-dev`, `vtkdata`

			Downloads are also available from the [https://www.vtk.org/download/ VTK home page].

			`ipython` keeps a nice history of the commands, try `history`, option `-g` displays also entries from previous sessions.

			Example: run command sequence in interactive mode (simple copy & paste)
			source = vtk.vtkPlaneSource()
			mapper = vtk.vtkPolyDataMapper()
			mapper.SetInputConnection(source.GetOutputPort())
			actor = vtk.vtkActor()
			actor.SetMapper(mapper)
			renderer = vtk.vtkRenderer()
			renderer.SetBackground(0.0, 0.0, 0.0)
			renderer.AddActor(actor)
			render_window = vtk.vtkRenderWindow()
			render_window.SetWindowName("Simple VTK scene")
			render_window.SetSize(400, 400)
			render_window.AddRenderer(renderer)
			# Create an interactor
			interactor = vtk.vtkRenderWindowInteractor()
			interactor.SetRenderWindow(render_window)
			# Initialize the interactor and start the
			# rendering loop
			interactor.Initialize()
			render_window.Render()
			interactor.Start()

Created page with "Main Page -> Documentation -> Visualization Toolkit (VTK) Installation and usage == Installation == === Source code === The Gate github repository can be cloned l..."

New page

[[Main Page]] -> [[Documentation]] -> [[Visualization Toolkit (VTK) Installation and usage]]
== Installation ==

=== Source code ===
The Gate github repository can be cloned like that
https://github.com/Kitware/VTK

This will bring you to the ''master'' branch, tags can be checked out like this
git checkout v8.0.1

=== Compilation ===
Make a build directory and execute in this directory `cmake <SOURCEDIR>`. Some interesting switches can be added with `-DSWITCH`
* `CMAKE_INSTALL_PREFIX`
* `VTK_WRAP_TCL` wrapper code for TCL
* `VTK_WRAP_PYTHON` wrapper code for Python
* `VTK_FORBID_DOWNLOADS` skip downloading of test data
* `VTK_RENDERING_BACKEND` default OpenGL2
* `BUILD_EXAMPLES` set to `ON` if examples should be built

Example session
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=../install -DVTK_WRAP_PYTHON=ON -DVTK_FORBID_DOWNLOADS=ON
make install

== Running ==
Make sure that the `bin` and `lib` directories of the installation are part of `PATH` and `LD_LIBRARY_PATH` respectively, e.g.
export PATH=/the_installation_directory/bin:$PATH
export LD_LIBRARY_PATH=/the_installation_directory/lib:$LD_LIBRARY_PATH

=== TCL bindings ===
Start `vtk` and get the interactive prompt. Or run one script of the examples directly, e.g.
vtk Examples/Tutorial/Step1/Tcl/Cone.tcl

=== Python bindings ===
Set `PYTHONPATH` to enable Python to find the available modules
PYTHONPATH=$VTK_install/lib/pythonx.x/site-packages

Run a script directly
python Examples/Tutorial/Step1/Python/Cone.py

=== Interactive Python ===
Run either `python` or `ipython` without arguments to come to the prompt. `ipython` can be recommended for interactive sessions.
