- Rename to_XNN and to_const_XNN functions to reflect the target data type they are converting to.
- Cleanup Angle namespace and remove all “inDegrees” parameters from rotation functions. Use aliases to differentiate between Degree and Radian parameters.
- Profile guided optimizations.

- Split Resource class into Resource and CachedResource
— CachedResource is the only resource held in a ResourceCache and loaded from a ResourceDescriptor
— CachedResource is mapped by its creation descriptor’s hash value, instead of the resource name
-— Multiple cached resources can now exist with the same name if the have different properties, for example.

- ShaderBuffers now decide heuristically if they get persistently mapped or not (depends on size. Current limit is 512Kb for subData calls.
- Separate visible node command generation into 2 steps: onRender and getDrawPackage. onRender allows the creation of parallel tasks that should finish by the time the second call, getDrawPackage reaches the same node
- Update ParticleEmitter to take into account multiple players and increase parallelism at the cost of memory consumption and complexity.
- Add a default bounding box for Players (add extents to SceneTransform nodes)
- All buffers (ShaderBuffer, d3dConstantBuffer, glUniformBuffer, glBufferImpl, glGenericBuffer, etc) use BufferParams for creation.
— Constructor and create calls have been merged together

- Singleton elimination update Part I: get it to compile
— The following classes are no longer Singletons: GFXDevice, GL_API, DX_API, SFXWrapper, FmodWrapper, SDLWrapper, ALWrapper, PXDevice, InputInterface, RenderPassManager, SceneManager and ResourceManager;
— Refactor system to a Context / Component based implementation (Pass relevant context to objects: e.g. GFXDevice object to Textures, GUI to GUIElements, etc)
— Make devices and managers components of the kernel
— Allow multiple Resource caches to co-exist. This may prove useful for later when a more fragmented memory model is need (per frame / per scene / global caches / etc)

  • next steps: part II – cleanup/refactor new code, part III – optimise code, part IV – remove remaining Singletons (e.g. Application, ParamHandler, FrameListenerManager, Recast, PostFX and DebugInterface)

- More performance tuning:
— Move billboarding related camera variable calculation to shaders instead of CPU
— Replace some DIVIDE_ASSERT calls with regular assert calls in really low level code.
— Some cleanup of the GenericDrawCommand class
— glRegularBuffer does an invalidation call before updating
— Misc changes

- Performance improvement: Create linear list of ordered SGNs for update and split update step in two to allow parallel tasks in the first step to finish before moving to second step
- Performance improvement: Remove glFlush calls for lock manager. Drivers should be up to the task now
- Performance improvement: Re-enabled round robin buffer system for ParticleEmitter

- Improved GenericVertexData structure (separate buffer data from attribute data entirely)
- Added a VAO pool for OpenGL so that all requested VAOs are allocated on the main thread
- Added a mainThreadTask system to queue a task to run on the main thread and optionally wait for it to complete
- Added the option to specify generic geometry for the particle system with an optional index buffer

[IonutCava]
- Massive rewrite of the resource system:
— ResourceCache now uses a map of weak pointers and passes shared pointers to the call point of CreateResource
— RemoveResource is no longer needed, but resource based smart pointers use a custom deleter that calls unload()
— Keep a shared_ptr of the resource in the entity that needs it and pass shared_ptr references from getter methods
-— All of this removed the need for calls to RemoveResource, REGISTER_TRACKED_DEPENDENCY and UNREGISTER_TRACKED_DEPENDENCY reducing the number of mutex locks and atomic exchanges
- Singleton cleanup:
— Removed ShaderManager singleton and merged it’s data and responsibilities in static methods in both ShaderProgram and Shader classes.
Explanation: Due to the complex interdependency chains in the system, copying, updating, tracking the cache in a thread safe way became a lot more slower than a straight forward smart pointer based implementation. (e.g. scene graph nodes have 3d objects and material instances, 3d objects have materials, materials have textures and shaders, etc)
