- 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.

- 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

- Split PlatformDefines.h into 2. Move data type defines to PlatformDataTypes.h
- Continue to improve velocity map calculation
- Remove “destroy()” calls from most classes. Attempt to move as many classes to the RAII system.

[IonutCava]
- 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)
