Howto Install and Configure VTK on Ubuntu

Howto Install and Configure VTK on Ubuntu

    Download vtk-5.10.1.tar.gz fromhttp://vtk.org/VTK/resources/software.html#latestand extract; $cd/home/chen/Downloads/VTK5.10.1/ $mkdir VTKBin $cd VTKBin $cmake .. $ccmake .. configure as follows:
    press c to configure, and press g togenerate and exit;
    $make copy the include files andlibraries to system directories: $sudo make install copy the plugin to qt:

      $cd /usr/lib/qt4 sudo mkdir plugins cd plugins sudo mkdir designer sudo cp~/Downloads/VTK5.10.1/VTKBin/bin/libQVTKWidgetPlugin. so/usr/lib/qt4/plugins/designer open qtcreator (can be installedfrom Ubuntu Software Center) create one Gui application and open the ui by qtdesigner tocheck QVTKWidget.

To use VTK in your own project, addfollowing to the CMakeLists.txt in your project:
########################################################
#VTK
#set(VTK_DIR”~/Downloads/vtk/VTK5.10.1/build”)
set(VTK_DIR “/usr/local/lib/vtk-5.10”)
find_package(VTK REQUIRED)
include(${VTK_USE_FILE})
########################################################

add target link libraries to yourproject: ${VTK_LIBRARIES} QVTK

A complete example of using VTKtogether with Qt in a CMake project can be found at:
http://blog.csdn.net/owldestiny/article/details/8806128.

Herewe give a complete CMake project using both Qt and VTK, the completeprogram can be download athttp://download.csdn.net/detail/owldestiny/5262489:
Theproject structure is:

Inthis project we do not use qrc.
