StyleSwitch
VTKExamples/Cxx/Interaction/StyleSwitch
Description¶
The class vtkInteractorStyleSwitch allows handles interactively switching between four interactor styles -- joystick actor, joystick camera, trackball actor, and trackball camera. Type 'j' or 't' to select joystick or trackball, and type 'c' or 'a' to select camera or actor. The default interactor style is joystick camera.

CMakeLists.txt¶
cmake_minimum_required(VERSION 2.8) PROJECT(StyleSwitch) find_package(VTK REQUIRED) include(${VTK_USE_FILE}) add_executable(StyleSwitch MACOSX_BUNDLE StyleSwitch.cxx) target_link_libraries(StyleSwitch ${VTK_LIBRARIES})
Download and Build StyleSwitch¶
Danger
The generation of tar files has not been ported to the new VTKExamples. Some tarballs may be missing or out-of-date.
Click here to download StyleSwitch and its CMakeLists.txt file. Once the tarball StyleSwitch.tar has been downloaded and extracted,
cd StyleSwitch/build
If VTK is installed:
cmake ..
If VTK is not installed but compiled on your system, you will need to specify the path to your VTK build:
cmake -DVTK_DIR:PATH=/home/me/vtk_build ..
Build the project:
make
and run it:
./StyleSwitch
WINDOWS USERS PLEASE NOTE: Be sure to add the VTK bin directory to your path. This will resolve the VTK dll's at run time.
