viewport settings in stereo mode. It seems that the SceneView::cull() method will pass the full size viewport to the left/right cullvisitors, instead of the modified stereo viewport. I made quite a few changes to SceneView to fix the issue. The SceneView::cullStage() method will now receive the viewport as an argument, instead of using the global viewport. The SceneView::cull() method will pass the modifed viewport to cullStage when rendering in stereo. There are 2 new private methods computeLeftEyeViewport() and computeRightEyeViewport() that will compute the stereo viewports. I also modified the draw() function so it applies the correct viewport to the prerender stages. These changes are only necessary for horizontal/vertical split stereo."

How to build the OpenSceneGraph
===============================
The OpenSceneGraph uses the CMake build system to generate a
platform-specific build environment. CMake reads the CMakeLists.txt
files that you'll find throughout the OpenSceneGraph directories,
checks for installed dependenciesand then generates the appropriate
build system.
If you don't already have CMake installed on your system you can grab
it from http://www.cmake.org, use version 2.4.6 or later. Details on the
OpenSceneGraph's CMake build can be found at:
http://www.openscenegraph.org/projects/osg/wiki/Build/CMake
Under unices (i.e. Linux, IRIX, Solaris, Free-BSD, HP-Ux, AIX, OSX)
use the cmake or ccmake command-line utils, or use the included tiny
configure script that'll run cmake for you. The configure script
simply runs 'cmake . -DCMAKE_BUILD_TYPE=Release' to ensure that you
get the best performance from your final libraries/applications.
cd OpenSceneGraph
./configure
make
sudo make install
Alternatively, you can create an out-of-source build directory and run
cmake or ccmake from there. The advantage to this approach is that the
temporary files created by CMake won't clutter the OpenSceneGraph
source directory, and also makes it possible to have multiple
independent build targets by creating multiple build directories. In a
directory alongside the OpenSceneGraph use:
mkdir build
cd build
cmake ../OpenSceneGraph -DCMAKE_BUILD_TYPE=Release
make
sudo make install
Under Windows use the GUI tool CMakeSetup to build your VisualStudio
files. The following page on our wiki dedicated to the CMake build
system should help guide you through the process:
http://www.openscenegraph.org/projects/osg/wiki/Support/PlatformSpecifics/VisualStudio
Under OSX you can either use the CMake build system above, or use the
Xcode projects that you will find in the OpenSceneGraph/Xcode
directory.
