[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]]

[Ionut] [[BR]]
- Improved batching part2: [[BR]]
— Moved all bone transformation matrices upload from uniform functions in SceneNode to Shader Storage Buffers in AnimationController class with updates controlled by SceneGraphNode’s AnimationComponent [[BR]]
-— No double-buffering or efficient mapping of data yet. Just raw buffer updates [[BR]]
— Replaced all RenderStateBlock* pointers with I64 hash values [[BR]]
-— Will be used later in draw commands as per-shader state hash [[BR]]
— Moved getShaderProgram from Material to Material::ShaderInfo [[BR]]
-— Improved redundant uniform checks [[BR]]
— Improved texture unit changing in case of redundant texture bind case (i.e. skip changing the texture unit) [[BR]]
[[BR]]
- Improved float and double comparison functions using algorithms described in http://randomascii.wordpress.com/2012/02/13/dont-store-that-in-a-float/ [[BR]]
- Added a new utility function, DIVIDE_ASSERT, to more easily bind an assert check with a specific message [[BR]]
- Added missing files from Forward+ renderer’s initial code [[BR]]

[Ionut] [[BR]]
- New camera system: [[BR]]
— Stack based (push/pop active camera) [[BR]]
— Per camera frustum [[BR]]
— Per camera projection [[BR]]
— Shadow mapping now uses the new camera system (each light has a shadow camera) [[BR]]
[[BR]]
- New terrain, water and vegetation system: [[BR]]
— Direct import of terrain from L3DT both as 8-bit grayscale and 16-bit raw formats [[BR]]
— Multiple alpha maps for texture splatting support [[BR]]
— Per texture detail map support [[BR]]
— Transform feedback based visibility culling for vegetation [[BR]]
— Alpha-map based vegetation placing on terrain [[BR]]
— Water now uses a refraction map instead of alpha blending for better refraction effects [[BR]]
[[BR]]
- SceneGraph improvements: [[BR]]
— Better bounding box updates from child to parent [[BR]]
— Better onDraw / postDraw implementation [[BR]]
[[BR]]
- Performance improvements: [[BR]]
— Batch 2D rendering tasks together as much as possible[[BR]]
— Improve renderStateBlock hash generation for better sorting [[BR]]
— Move most state related gfx changes from API implementation to the GFXDevice class [[BR]]
— Move viewport stack to the GFXDevice class [[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]]

-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]]

[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]]
