[Ionut]
- Replaced all tabs with 4 spaces (some spacing may be off now. no way to check all the files.)
- Moved implementation details for ParamHandler, BoundingBox, BoundingSphere and ProfileTimer to proper .inl and .cpp files. (more to follow)
- Update all forward declared enums with the required storage type (as requested by the C++11 standard)

[Ionut]
- Reorganized the Hardware project and renamed to "Platform"
- Reorganized the Server project

[Ionut]
- Limited line length to 132 characters to improve readability and diff-comparisons
- Refactored memory allocation/deallocation functions
- Fixed a few compatibility issues with HashMap.h
- Fixed a bug in GPU Skinning shaders (cast a float to int)

[Ionut]
- Refactored most of Boost related code to be C++11 based
— Boost is only used for ThreadPool, Mutex handling, XML parsing and networking (ASIO)
— Function binds, threads, regex, NonCopyable base, Hashing algorithms and more are now using C++11 libraries
- Replaced all FOR_EACH calls with standard, range, “for” calls

[Ionut]
- Wrapped the entire code in a “Divide” namespace
- VertexBuffers now call “shrink_to_fit” on all internal data storage
- Improved some vector performance by preferring “emplace_back” instead of “push_back” + proepr usage of reserve / resize
- Wrapped OIS specific types and classes in Divide::Input namespace
- Added the messageBox.layout file (forgot it in the previous few commits)

[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]]

272 Diff Diff IonutCava picture IonutCava Wed 11 Jun, 2014 11:30:51 +0000

[Ionut] [[BR]]
- Added initial code for Forward+ rendering (grid based light culling) [[BR]]
- Simplified Light class [[BR]]
- Moved more light uniform data to ShaderBuffers [[BR]]
- Double buffered grass rendering [[BR]]
- Added a better attribute interface to GenericVertexData [[BR]]
- Fixed screenshot capture [[BR]]
- Fixed texture double-bind checks [[BR]]

[Ionut] [[BR]]
- All texture objects now properly allocate storage using glTextureStorage*D(w-w/o Multisampled) [[BR]]
- Removed useless “format” element from TextureDescriptor. Format is deduced from the internal format specified (RGBA8 uses RGBA. RG32F uses RG) [[BR]]
- Use GLM only with radians [[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]]

[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]]
