[Ionut] [[BR]]

    • very buggy commit ** [[BR]]

- New rendering pipeline: [[BR]]
— Bumped OpenGL version to 4.4 [[BR]]
— Command based rendering. GFXDevice dispatches rendering commands to their respective buffers [[BR]]
— State changing is exclusively controlled by the GFXDevice class [[BR]]
— Material properties and transform matrices are stored in shader storage buffers that are updated after culling and uploaded once per RenderPass. Objects use drawIDs to index data in shaders [[BR]]
— Removed all custom matrices and other, per shader, bind data [[BR]]
— Removed per node light data. Light culling and shader buffers will replace the old light management system [[BR]]
— Framebuffers now use the Texture class for attachments [[BR]]
— Sampler objects now work like RenderStateBlocks. GL_API handles them and stores them in a hash indexed map [[BR]]
— Removed “prepareMaterial” calls. Pre-draw material setup is now only limited to texture binding [[BR]]
— Moved immediate mode emulation and primitive rendering from API level to GFXDevice level [[BR]]
— Framebuffer rendering must be completed with a call to end() to ensure proper MSAA resolve (asserts, otherwise) [[BR]]
- Fixed hash code generation for RenderStateBlock (and now, glSamplerObject) using boost::hash_combine [[BR]]
- Temporarily disabled XML caching for materials [[BR]]

[[BR]]
- New terrain, water and vegetation system: [[BR]]

— Multiple alpha maps for texture splatting support [[BR]]
— Per texture detail map support [[BR]]
— Transform feedback based visibility culling for vegetation [[BR]]

[[BR]]
- Performance improvements: [[BR]]

— Added various performance counters (frame duration with round-robin query system, draw call count, etc) [[BR]]
— Fixed and improved clip plane management [[BR]]
— Delete client-side texture data after GPU upload [[BR]]
[[BR]]
- New features: [[BR]]
— Added callback support to the Task class so that a specific task may call a function in the main thread upon completion [[BR]]
— Added mouse-wheel zoom support to Orbit/ThirdPerson cameras [[BR]]
— Added 2D Texture Array support (e.g. used for terrain textures) [[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]]
-Separated responsibilities between “Application” and “Kernel” [[BR]]
--“Application” handles data such as window dimensions, logs, “ParamHandler” etc [[BR]]
--“Kernel” handles the main loop, SFX, GFX, physics, sceneManager etc updates [[BR]]
---“Kernel” is now a “Core” component [[BR]]
-Reduced coupling between some classes by passing more info via parameters rather than relying on singleton access [[BR]]
--Ex: eyePos in “Terrain”,“Water” and “Trigger” classes is now passed as a "vec3<F32>" on render call rather than querying “CameraManager” [[BR]]
-Reworked “GLWrapper” shutdown routine [[BR]]
Singleton witch hunt [[BR]]
-“Kernel” is no longer a singleton and it’s initialized on application startup in the “Application” class[[BR]]
-“CameraManager” is no longer a singleton and it’s instantiated in the kernel [[BR]]

[Ionut] [[BR]]
-Removed now useless “BaseCache” class as a simple unordered_map in each manager-type class is all that’s needed [[BR]]
-Moved loading responsibility from each Resource implementation to each "ImplResourceLoader<T>" class (defaults via macro’s are available for convenience) [[BR]]
--Resources now have a “setInitialData” method for setting post-load values [[BR]]
--Also added a loader for Particle Emitters [[BR]]
-Added a new class, “HardwareResource” (for textures, shaders, etc) that needs special loading routines to facilitate future multi-threaded asset streaming [[BR]]
--HardwareResource’s have a “generateHWResource” that should be called after threaded loading routines join with main thread [[BR]]
-Renamed “Guardian” class to “Kernel” as that’s what it’s new responsibility will be in future revisions [[BR]]
-Added the “threadpool” library from here: http://threadpool.sourceforge.net/ (not used yet) [[BR]]
-Added some more macro’s and cleanups [[BR]]
