Description¶
This currently crashes - still trying to decide how to best display these graphs.

CMakeLists.txt¶
cmake_minimum_required(VERSION 2.8) PROJECT(SideBySideGraphs) find_package(VTK REQUIRED) include(${VTK_USE_FILE}) add_executable(SideBySideGraphs MACOSX_BUNDLE SideBySideGraphs.cxx) target_link_libraries(SideBySideGraphs ${VTK_LIBRARIES})
Download and Build SideBySideGraphs¶
Danger
The generation of tar files has not been ported to the new VTKExamples. Some tarballs may be missing or out-of-date.
Click here to download SideBySideGraphs and its CMakeLists.txt file. Once the tarball SideBySideGraphs.tar has been downloaded and extracted,
cd SideBySideGraphs/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:
./SideBySideGraphs
WINDOWS USERS PLEASE NOTE: Be sure to add the VTK bin directory to your path. This will resolve the VTK dll's at run time.
