Download and Build ParallelCoordinates¶
Click here to download ParallelCoordinates and its CMakeLists.txt file. Once the tarball ParallelCoordinates.tar has been downloaded and extracted,
cd ParallelCoordinates/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:
./ParallelCoordinates
WINDOWS USERS
Be sure to add the VTK bin directory to your path. This will resolve the VTK dll's at run time.
