[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]]
- 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]]

- 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]]

— VAO rendering is self contained (no more enable/disable calls before a draw request) [[BR]]

[Ionut] [[BR]]
Features: [[BR]]
-Added a proper RenderState Management system similar to the D3D default one[[BR]]
--All possible states are managed: cull, blend, alpha-blend, color mask, lighting, stencil mask, fill mode etc [[BR]]
--Every material has different states for normal rendering, shadow rendering and reflection rendering [[BR]]
--Nodes are sorted by shader first then by state hash depending on current render stage [[BR]]
--Redundant states are not changed [[BR]]
--Every entity submits it’s desired state before render [[BR]]
--Every state is checked before rendering a VBO or other primitive type[[BR]]
[[BR]]
-Added a Reflector base class used for reflection calculations and updates (useful for water, mirrors, portals etc)[[BR]]
--Reflections are triggered between pre-render and render calls [[BR]]
--Water now derives from Reflector class as well [[BR]]
[[BR]]
-Material now properly calculates if it has transparency or is double sided, setting desired states to handle this feature (cull, blend) [[BR]]
-Added some basic defines or inline template functions to facilitate access to useful classes and methods (hardware devices, resource management, console printing, etc) [[BR]]
-Lights are updated after every camera update[[BR]]
-Added a new FrameListener event triggered after pre-render call is finished (used by reflectors) [[BR]]
