### Download and Build ImplicitDataSet

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

    cd ImplicitDataSet/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:

    ./ImplicitDataSet
