- 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]]
— OpenGL 3.x clean context (glLight commands are still used for now, but UBO support is there, but not used yet) [[BR]]
— Custom matrix stacks and UBO based shader data (UBOs cause some link errors on some nVidia cards)[[BR]]
— Multi-threaded texture loading and shader compilation (mt shader compilation disabled for now. needs more tests) [[BR]]
— VAO rendering is self contained (no more enable/disable calls before a draw request) [[BR]]
— Render instance class used for rendering information [[BR]]
[[BR]]
- New unique ID generation base class: GUIDWrapper. Each class that derives from this, gets an application wide unique id on construction [[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]]

[Ionut] [[BR]]
- Better ReCast integration [[BR]]
— Any entity can be used as an obstacle in the NavMesh if that’s specified in each scene’s assets.xml file for said entity [[BR]]
— New console command, “createNavMesh”, that passes geometry data to ReCast [[BR]]
-— NavMesh generation is not yet complete [[BR]]
- Better PhysX integration [[BR]]
— Each scene passes data to and gets data from the Physics API better and safer[[BR]]
- Multi-threaded support extended: [[BR]]
— Event class replaced with Task [[BR]]
— Kernel uses a threadpool for scene tasks [[BR]]
— Each task can be added to a different threadpool if needed [[BR]]
— Most critical sections use the new boost::atomic wrapper for thread safety [[BR]]
- Rendering system updated [[BR]]
— VBO’s keep track of the geometry type internally [[BR]]
— Rendering by specific element list is internal to the VBO [[BR]]
— VBO’s can draw a “lite” version that doesn’t send Tangent, BiTangent and TexCoord data for depth rendering (disabled) [[BR]]
- Reflectors now offer a preview of the generated reflective texture if needed [[BR]]
- Buttons are now added and rendered by CEGUI [[BR]]
[[BR]]
Deprecation: [[BR]]
- Removed fixed pipeline material system [[BR]]
- Removed BoundingBox late update system [[BR]]
- Shadow references in the material system are now depth references [[BR]]
[[BR]]
Bug fixes: [[BR]]
- Problematic FBO double bind check removed [[BR]]
- Faster terrain rendering via chunk size selection through each scene’s terrain.xml[[BR]]
- Rendering is paused when the window is minimized [[BR]]
- CEGUI and impostors now render properly in deferred rendering mode [[BR]]
- Fixed various level 4 (VS2008) warnings [[BR]]
- Better state management and cleaning [[BR]]
- Better SceneGraph node management and trasformation/AABB update calls [[BR]]
- AITenisScene has proper collisions now [[BR]]
