OsgOculusViewer - osgViewer

An example of an open scene graph standard viewer using the Oculus Rift

Release highlights:

• Tested successfully against Oculus SDK 0.2.5.
• Implemented support for OpenSceneGraph osgViewer::ViewConfig concept.
• Wrapping the oculus code into a library.

Minor Improvements:

• Early warnings if OSG_DIR and OCULUS_SDK_ROOT_DIR are not specified in environment variable.
• Add statistics handler in example program.
• Made oculusdevice class inherit from osg::Referenced
• Renamed the old viewer example and library to _deprecated.
• Marked some CMake options as advanced, ie. relative paths and multiprocessor compilation on win32 platform.

Bugfixes:

• Moved the disabling of computation of near and far plane calculations from slave cameras to main camera. Which solves clipping errors when rotating the HMD.
• Removed an unnecessary check that a pointer value is not NULL before doing delete. The delete operator already handles NULL pointers correctly.
