source: sandbox_light/src/external/ogremath/OgrePlatform.h @ 6042

Last change on this file since 6042 was 5789, checked in by rgrieder, 15 years ago

Stripped sandbox further down to get a light version that excludes almost all core features.
Also, the Ogre dependency has been removed and a little ogremath library been added.
