Download and Build Cube1¶

Click here to download Cube1 and its CMakeLists.txt file. Once the tarball Cube1.tar has been downloaded and extracted,

cd Cube1/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:

./Cube1

WINDOWS USERS

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