### Download and Build AnnotatedCubeActor

Click here to download AnnotatedCubeActor and its CMakeLists.txt file. Once the tarball AnnotatedCubeActor.tar has been downloaded and extracted,

    cd AnnotatedCubeActor/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:

    ./AnnotatedCubeActor

WINDOWS USERS

Be sure to add the VTK bin directory to your path. This will resolve the VTK dll's at run time.
