- Reworked the Camera class[[BR]]
— Now fully quaternion based [[BR]]
— Basic camera types added but not used yet (third person, first person, orbit) [[BR]]
- Cleaned up Material and Texture handling [[BR]]
- Added clipping plane support [[BR]]
— Similar to OpenGL fixed-function clip planes but fully shader driven [[BR]]
— Added a new class, “Plane”, that helps define clip planes [[BR]]
- Optimized the Singleton class to allow faster “getInstance” calls without performance penalties [[BR]]
-- “createInstance” must be called for each singleton class before usage. Or “gerOrCreateInstance” can be used, which is basically the former “getInstance” implementation [[BR]]
- Improved console logging by changing some heap allocations to stack and removing dependencies on the std::string class [[BR]]
- Added a lot of performance optimizations related to coding standards and redundant calculations [[BR]]
— e.g. Frustum AABB check didn’t need to recompute the AABB points as they were calculated already [[BR]]
— e.g. A vector did not need to be set to 0 on initialization as that is already it’s default state on creation [[BR]]
— e.g. Faster Framerate and Timing calculations by using less member variables that are not needed outsied of calling functions [[BR]]
- The SceneState now contains the SceneRenderState and is passed on to the SceneGraph’s update calls [[BR]]
- Better material export/import to/from XML format [[BR]]
- More bug fixes and cleanups [[BR]]

[Ionut] [[BR]]
- New rendering pipeline (experimental and unstable): [[BR]]

- Added base code for an in-game editor using CEGUI [[BR]]
- Replaced some mutex locks with lockless data structures or atomic data [[BR]]
- CEGUI 0.8.2, FTGL-GL3 and GLIM 0.4 modified to support GLEW_MX if defined [[BR]]
- Dropped VS2008 support [[BR]]
- Networking library, server framework and ReCast files are now projects inside the Divide Framework solution [[BR]]
- New console command “setFov” that modifies the horizontal FoV value in realtime [[BR]]
- New console command “recompileShader” that reparses shader files, recompiles shaders and relinks shader programs who’s names match or contain the argument string [[BR]]
- New debug utility: axis angle drawn in corner of the screen if needed [[BR]]
- More ‘const’-s pasted around the code, more loop performance tweaks (allocations before a loop, tighter loops, etc), more utility member functions added to various classes [[BR]]
