[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]]

— 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]]

— 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]]

— Shadow mapping now uses the new camera system (each light has a shadow camera) [[BR]]
[[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]]

[Ionut] [[BR]]
- Fullscreen quads are now rendered via Geometry Shaders [[BR]]
- Implemented shader subroutines [[BR]]
- Improved CVSM’s quality [[BR]]
- Separated shadow only light properties from general light properties in separate UBOs to improve update performance [[BR]]
- Removed shader mask and instead try to load all available shaders from a given file [[BR]]
- Added a method (hackish) of changing projection properties at runtime (e.g. z planes) [[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]]

Ionut: [[BR]]
- Code cleanups and optimizations [[BR]]
- Better memory allocation and deallocation tracking and logging [[BR]]
- Added vertex color support for VBOs [[BR]]
-Improved PostProcessing: [[BR]]
— A lot of code cleanups and scalability was increased [[BR]]
-— HDR lighting with automatic exposure, God Rays and working SSAO will be added in the next commit [[BR]]
— Added single pass SSAO by Aurel Manea [[BR]]
-— Not finished – a lot of artifacts [[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]]
