[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]]

[IonutCava] [[BR]]
- Terrain and vegetation updates: [[BR]]
— Use standard phong lighting model [[BR]]
— Separate grass patches per chunk [[BR]]
— Reduce number of required texture bind points for terrain by adding both textures and normal maps in a single texture array [[BR]]
— Draw terrain with 2 drawcalls (using glMultiDrawElements twice, once for LoD == 0 and once for LoD > 0) [[BR]]
[[BR]]
- Buffer management updates: [[BR]]
— Unified buffer binding system [[BR]]
— Made Uniform buffer objects visible to all classes and moved lightUBO to LightManager, matricesUBO to GFXDevice etc [[BR]]
— Added initial support for Shader Buffer Objects [[BR]]
— Moved viewport management to GFXDevice class [[BR]]
[[BR]]
- Rendering improvements: [[BR]]
— Added Hi-Z occlusion culling to instanceCull shader (using Hi-Z depth buffer constructed in GFXDevice class) [[BR]]
— Resolved issues with shadow maps overriding texture bind locations [[[BR]]
— Improved shader and shader program loading [[BR]]
— Improved material transparency support [[BR]]
— Added buffer lock manager class from “Approaching Zero Driver Overhead in OpenGL (Presented by NVIDIA)” speech at GDC14 [[BR]]

[Ionut] [[BR]]
- More work on CSM. Reverted back to VSM to allow easier blurring and filtering [[BR]]
- Rewrote FrameBuffer classes to fix MSAA and memory leaks that occurred on resize (double creation of textures) [[BR]]
— Removed FBType. FrameBuffer types depend only on attachment types and if it’s MSAA enabled or not [[BR]]
- Rewrote RenderState classes to be API agnostic [[BR]]
- Bug fixes in math classes [[BR]]
- Changed “resolution change” logic [[BR]]
- Simplified some options in config.xml [[BR]]
- Improved per-light shadow options [[BR]]

[Ionut][[BR]]
- Implemented Exponential Stable Cascaded Shadow Maps for directional lights (still buggy, but basically working) [[BR]]
— CSM settings (resolution, number of splits, etc) are part of the scene render state [[BR]]
- SGN can skip rendering for the current frame if they are not ready (e.g. OnDraw can now return false or materials can fail to bind) [[BR]]
- Frustum class is now using the Plane class [[BR]]
- Removed Math SIMD implementation as the compiler generated code will always be faster and safer [[BR]]
- Added a “STUBBED” macro for outputing to the error stream of important messages (instead of using #pragma message) [[BR]]
- Added “freeze time” logic to pause/resume updates with or without freezing the GUI too [[BR]]
- Added “processGUI” method the every Scene class to separate time-sensitive GUI updates from game logic loop [[BR]]
- GLSL <-> Vertex Buffer bind locations are automatically set for every vertex shader [[BR]]
- Added basic support for compute shaders [[BR]]
- Removed most OS define checks to make porting to a new platform easier [[BR]]
- Texture transparency check per-pixel is now using OpenMP [[BR]]
- Texture samplers can now set a border color for CLAMP_TO_BORDER wrap mode [[BR]]
- Removed “Object” suffix from GFX Classes (pixel buffer, vertex buffer, frame buffer, etc) [[BR]]
- Stop processing scene input when application looses focus [[BR]]
- SceneGraphNode class is now responsible for updating SGNComponents on draw and calling its _node’s OnDraw method [[BR]]
- UBOs can now list all of the active uniforms inside a block with info such as type and offset [[BR]]
- Removed deprecated ‘GLCheck’ macro [[BR]]
- A lot of bug fixes and performance improvements in various places [[BR]]

[Ionut] [[BR]]
- Performance optimizations: [[BR]]
— Call SceneGraph::Update only once per frame (instead of once per draw call, as it was stupidly done now) [[BR]]
— Improve Shader programs' uniform system to allow better caching systems [[BR]]
— Use better caching system for Shader programs [[BR]]
— Use LOD for particle emitters (reduce count with distance for now) [[BR]]
- Every TrackedObject gets a GUID now [[BR]]
- Cleanup in SceneGraphNode class and SceneNode class (with derived classes as well) [[BR]]
- Some const-correctness fixes [[BR]]

[Ionut] [[BR]]
- Added AESOP library http://code.google.com/p/aesop-open-planner/ [[BR]]
- Performance optimizations: [[BR]]
— Update animations only for visible nodes (must handle special cases when nodes are just outside the frustum) [[BR]]
— Compile shaders only for the current stage when the material is requested (as opposed to compiling shaders for all the rendering stages when first accessing the material)[[BR]]
- Renamed Coordination to AITeam [[BR]]
