Download and Build ImagePlaneWidget

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

cd ImagePlaneWidget/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:

./ImagePlaneWidget
