MultipleRenderWindows
VTKExamples/Cxx/Visualization/MultipleRenderWindows
Description¶
This example creates 4 render windows. When you close one, the next one opens? Or do they all open simultaneously?

CMakeLists.txt¶
cmake_minimum_required(VERSION 2.8) PROJECT(MultipleRenderWindows) find_package(VTK REQUIRED) include(${VTK_USE_FILE}) add_executable(MultipleRenderWindows MACOSX_BUNDLE MultipleRenderWindows.cxx) target_link_libraries(MultipleRenderWindows ${VTK_LIBRARIES})
Download and Build MultipleRenderWindows¶
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 Some tarballs may be missing or out-of-date.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 MultipleRenderWindows and its CMakeLists.txt file. Once the tarball MultipleRenderWindows.tar has been downloaded and extracted,
cd MultipleRenderWindows/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:
./MultipleRenderWindows
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.
