[Ionut] [[BR]]
- Migrated to platform toolset v100 [[BR]]
- Updated boost to 1.55 [[BR]]
- Moved from “NULL” to “nullptr” [[BR]]
- DevIL is now linked dynamically [[BR]]

[Ionut] [[BR]]
- More work and bugfixes with the branch reintegration [[BR]]
- Fixed GPU performance queries [[BR]]
- Fixed some FBO creation issues with multisampled textures [[BR]]
- Current issues: [[BR]]
— Terrain rendering not working on AMD [[BR]]
— Reflections not working on AMD & nVidia [[BR]]
— Grass rendering using TRIANGLE_STRIPS not complete yet [[BR]]

[Ionut] [[BR]]
- Merged branch “Shadows And Animations” back into trunk [[BR]]
- Added DoxygenGUI project file [[BR]]

[Ionut][[BR]]
- Path generation between 2 points using a specified NavMesh (Part 1 / 3 - “Base Code”) [[BR]]

-Moved hardware related code to a separate project [[BR]]
-More work on post-processing: [[BR]]
— HDR rendering is working, but final tonemapping needs more work [[BR]]
-Important changes in BloomPreRenderOperator.cpp, PostFX.cpp and glFrameBufferObject.cpp [[BR]]
-Trailing and leading whitespace cleanups [[BR]]

- 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]]
- Changed licensing from LGPL to the MIT license [[BR]]
— Code can now be used in non-commercial or commercial closed or open source projects [[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]]
- Changed the ParamHandler from using “boost::any” to the more faster “cdiggins::any”. More info here: http://bit.ly/YVGa9X [[BR]]
- Disabled mutexes from BoundingBox. Thread safety should be applied from a higher level [[BR]]
- Fixed a bug with important light selection for scene nodes [[BR]]
- Fixed a bug with material cache involving bump maps [[BR]]
- Fixed a bug with priority vertex properties for GLSL shaders [[BR]]
