Autodesk FBX SDK 2013.3，2012年9月11日

1.新功能和弃用功能
------------------------------

1.1新功能
    
    *类FbxCameraManipulator已经改进，使FrameAll和  FrameSelected函数现在考虑变形，并且      正确调整相机距离，以更好的框架。
      
    *删除了FbxNode_internal类。现在FbxNode的所有属性都是      在FbxNode类声明内部可见。这造成一些      更改为Pivot信息。
      
    *现在FbxCache使用IFF组件可以扩展到64位，允许      需要使用大得多的缓存文件。

* Windows上的FBX SDK库的动态库版本      平台现在使用静态MSVCRT（/ mt）而不是动态MSVCRT      （/ MD）。这允许使用FBX SDK dll分发应用程序      而无需安装Microsoft Visual Studio Redist。
      
    *从现在起，所有以前重载克隆的类现在只有      克隆本身，而不是其来源。例如，克隆FbxNode将      不再克隆其FbxNodeAttribute。相反，重现这一点      行为，必须使用处理克隆对象的FbxCloneManager      网络。这对于FBX SDK的大多数对象来说都是如此。然而，      对象（如与其外表和集群的网格）仍保持被视为      一体。
      
    * FbxScene类现在重载了Clone函数，并使用      FbxCloneManager成功克隆整个场景网络。
      
    * FBX SDK现在使用默认内存分配函数      调用而不进行初始化。这只发生在静态变量      在main之前被初始化。如果需要更改FBX SDK内存      分配函数，确保你没有使用静态FBX SDK对象      这可能在您的主要调用之前初始化。
      
    *添加了新的功能来检索当前的内存分配功能      设置，以及默认的。请参阅fbxalloc.h文件。
      
    *添加了对属性上的“锁定”标志的支持。这不会阻止FBX      SDK用户从更改属性值，但它将允许应用程序      以存储/检索标志。由于属性最多可以有4个
      成员，我们使用4位来区分它们。
      
1.2弃用的功能

*此版本中没有新弃用的功能。

3.从以前的版本释放注释
---------------------------------------

2013.2

*基本Lambert和Phong材料属性现在可以动画。
    
    *所有FBX产品的安装路径现在一致。例如，      FBX SDK现在将安装在“... / FBX / FBX SDK / 20xx.x”。
      
    *在Linux 32位上添加了对FBX Python SDK的支持。
    
    *添加了新功能来评估相机目标，这将进入      帐户在节点上指定的Target-Up对象位置。
      
    *为读者和作者注册过程添加了新参数      现在可以覆盖一个，而不是只是在末尾添加它      列表。
      
    *在Windows平台上删除了对WININET库的依赖。现在，当      与FBX SDK链接，不会生成其他依赖关系。所有样品      已更新以反映此。
      
    * FBX SDK库现在大约减少了10％，因为很多过时      代码已删除。
      
    *构造函数和析构函数已经标准化      整个SDK。现在，所需的构造函数声明一个类时      继承自FbxObject是在FBXSDK_OBJECT_DECLARE中默认定义的      宏。如果你需要在构造函数或析构函数中执行代码，你将需要覆盖Construct和Destruct详细的      文档。
      
    *虚函数ConstructProperties签名现在没有任何      返回值。请相应更新您的代码。请提醒一下      不要忘记在开始调用ParentClass :: ConstructProperties      如果你打算覆盖它。
      
    * FbxRedBlackTree已经被移动到自己的文件，这使得更容易      立即阅读fbxmap.h。
      
    * FbxScopedPtr类已重命名为FbxAutoPtr并已移动      在fbxalloc.h所以它是默认可访问的。此外，几个基本的重载      与不同的删除政策已经实施。那些是      FbxAutoFreePtr，FbxAutoDeletePtr和FbxAutoDestroyPtr。
      
    * FBX SDK的所有函数，用于获取ClassId或FBX_TYPE      宏作为过滤的输入现已被弃用。现在，模板      必须使用相同函数名称的版本。由于它是模板，      它们现在返回正确的值类型，并且它不再需要      调用FbxCast对返回值。
      
    *修复了使用经典求值程序指定“ApplyTarget”时出现的问题。
      
    * FBX SDK中的tangents / binormals生成函数已经      更新，现在工作在三边以上的多边形。

* FbxExposureControl类已停用。
    
    * FbxPlug类已退役。
    
    *函数FbxProperty :: GetCurve不再模板。
    
    *函数FbxObject :: GetRootProperty现在已被弃用。请使用      成员FbxObject :: RootProperty。
      
    *函数FbxCamera :: GetUpVector现已废弃。请用      FbxCamera :: EvaluateUpDirection。
      
    *函数FbxCamera :: ComputePerspective现已废弃。请用      FbxCamera :: ComputeProjectionMatrix。
      
    * fbxcompatibility.h文件中已弃用的函数已删除。
    
    * FbxPointerGuard类已经退役，因为FbxAutoPtr及其      派生代替它。
      
    *函数FbxArray :: SetCount已停用。请用      FbxArray :: Reserve或FbxArray :: Resize。
      
    *函数FbxArray :: Empty现在已被弃用。请用      FbxArray :: Clear。
    
    *函数FbxArray :: FindAfter现已废弃。请用      FbxArray :: Find代替。
      
    *现在已弃用函数FbxArray :: FindBefore。请用      FbxArray :: FindReverse。
      
    *函数FbxArray :: AddMultiple现在已被弃用。请用      FbxArray :: Grow。
      
    * FbxObject，FbxProperty，FbxCollection和FbxDocument中的所有函数      用于获取FbxClassId或FBX_TYPE（）宏作为过滤机制，现已废弃。请使用这些的模板版本      函数，如：FbxObject :: GetSrcObjectCount <Type>（）或      FbxObject :: GetSrcObject <Type>（）模板版本返回正确的      类型，所以它不再需要使用FbxCast返回这些      功能。
      
    * FbxObject和FbxProperty中的所有函数，用于获取FbxClassId      加上一个FbxCriteria已退休，而不是被弃用，      因为他们从逻辑的立场没有意义，现在可以      安全地替换为形式Obj-> Function <Type>（Criteria）。
      
    *以下函数已弃用，应予以替换
      与他们的等价物在FbxObject中找到：
        FbxConnectSrc（Dst，Src） - > Dst-> ConnectSrcObject（Src）
        FbxConnectDst（Src，Dst） - > Src-> ConnectDstObject（Dst）
        FbxGetSrcCount（Obj） - > Obj-> GetSrcCount（）
        FbxGetSrcCount（Obj，ClassId） - > Obj-> GetSrcCount <Type>（）
        FbxGetSrc（Obj，Index） - > Obj-> GetSrcObject（Index）
        FbxGetSrc（Obj，Index，ClassId） - > Obj-> GetSrcObject <Type>（Index）
        FbxFindSrc（Obj，Name，Index） - > Obj-> FindSrcObject（Name，Index）
        FbxFindSrc（Obj，Name，ClassId，Index） - > Obj-> FindSrcObject <Type>（Name，Index）
        FbxDisconnectAllSrc（Obj） - > Obj-> DisconnectAllSrcObject（）
        FbxGetDstCount（Obj） - > Obj-> GetDstCount（）
        FbxGetDstCount（Obj，ClassId） - > Obj-> GetDstCount <Type>（）
        FbxGetDst（Obj，Index） - > Obj-> GetDstObject（Index）
        FbxGetDst（Obj，Index，ClassId） - > Obj-> GetDstObject <Type>（Index）
        FbxFindDst（Obj，Name，Index） - > Obj-> FindDstObject（Name，Index）
        FbxFindDst（Obj，Name，ClassId，Index） - > Obj-> FindDstObject <Type>（Name，Index）
        FbxDisconnectAllDst（Obj） - > Obj-> DisconnectAllDstObject（）

*修正缩放继承没有正确计算的问题      经典评估器。
      
    *由FBX SDK生成的切线和binormals现在将平滑      根据正常平滑。
      
    *优化切线/ binormals生成，以便没有更多的      比网格上有法线。

Autodesk FBX SDK 2013.3, September 11th 2012

1. NEW AND DEPRECATED FEATURES
------------------------------

1.1 New Features

* The class FbxCameraManipulator has been improved so that the FrameAll and
FrameSelected functions now take deformations into account, and also
properly adjust the camera distance for a better framing.

* Removed the FbxNode_internal class. Now all attributes of FbxNode are
visible within the FbxNode class declaration itself. This caused some
changes to the Pivot informations.

* Now the FbxCache using IFF component can scale to 64bit, allowing for
much larger cache files to be used.

* The dynamic library version of the FBX SDK library on the Windows
platform now use the static MSVCRT (/mt) rather than the dynamic MSVCRT
(/MD). This allows to distribute applications using the FBX SDK dll
without having to install the Microsoft Visual Studio Redist.

* From now on, all classes that previously overloaded Clone will now only
clone itself, and not its sources. For instance, cloning an FbxNode will
NOT clone its FbxNodeAttribute anymore. Instead, to reproduce this
behavior, one must use the FbxCloneManager which handles cloning object
networks. This now holds true for most objects of the FBX SDK. However,
objects such as meshes with their skins and clusters remain considered as
one entity.

* The class FbxScene now overload the Clone function, and uses the
FbxCloneManager to successfully clone the entire scene network.

* The FBX SDK now use default memory allocation functions when they are
called without being initialized. This only happens when static variables
are initialized before main. If you need to change the FBX SDK memory
allocation functions, make sure you are not using static FBX SDK objects
that could potentially be initialized before your main call.

* Added new functions to retrieve the memory allocation function currently
set, as well as the default ones. Please see fbxalloc.h file.

* Added support for 'locked' flags on properties. This won't prevent FBX
SDK users from changing property values, but it will allow applications
to store/retrieve the flags across. Since properties can have up to 4
members, we're using 4 bits to differenciate them.

1.2 Deprecated Features

* No newly deprecated features in this version.

3. RELEASE NOTES FROM PREVIOUS RELEASES
---------------------------------------

2013.2

* Basic Lambert and Phong material properties are now animatable.

* Installation paths for all FBX products is now consistent. For instance,
the FBX SDK will now install in ".../FBX/FBX SDK/20xx.x".

* Added support for FBX Python SDK on Linux 32bit.

* Added new function to evaluate camera target up, that will take into
account the Target-Up object position specified on the Node.

* Added new parameter to Readers and Writers registration process so that
now it is possible to override one, rather than just add it at the end of
the list.

* Removed dependency to WININET library on the Windows platform. Now, when
linking with the FBX SDK, no other dependency are generated. All samples
have been updated to reflect this.

* The FBX SDK library is now roughly ~10% smaller, since a lot of obsolete
code has been removed.

* The constructor and destructor mechanics have been standardized across
the whole SDK. Now, the required constructor when declaring a class that
inherit from FbxObject is defined by default in the FBXSDK_OBJECT_DECLARE
macro. If you need to execute code in the constructor or destructor, you
will need to override Construct and Destruct as detailed in the
documentation.

* The virtual function ConstructProperties signature now do not have any
return value. please update your code accordingly. As a reminder, please
do not forget to call ParentClass::ConstructProperties at the beginning
if you intend to override it.

* FbxRedBlackTree has been moved into its own file, which makes it easier
to read fbxmap.h now.

* The class FbxScopedPtr has been renamed FbxAutoPtr and has been moved
in fbxalloc.h so it is accessible by default. Also, a few basic overloads
with different deletion policy have been implemented. Those are
FbxAutoFreePtr, FbxAutoDeletePtr and FbxAutoDestroyPtr.

* All functions of the FBX SDK that used to take a ClassId or a FBX_TYPE
macro as input for filtering are now deprecated. Now, the templated
version of the same function name must be used. Since it is templated,
they now return the correct value type, and it is no longer necessary to
call FbxCast on the return value.

* Fixed an issue when specifying "ApplyTarget" with the classic evaluator.

* The tangents/binormals generation function in the FBX SDK has been
updated and now works on polygons with more than three sides.

* The class FbxExposureControl has been retired.

* The class FbxPlug has been retired.

* The function FbxProperty::GetCurve is not templated anymore.

* The function FbxObject::GetRootProperty is now deprecated. Please use the
member FbxObject::RootProperty instead.

* The function FbxCamera::GetUpVector is now deprecated. Please use
FbxCamera::EvaluateUpDirection instead.

* The function FbxCamera::ComputePerspective is now deprecated. Please use
FbxCamera::ComputeProjectionMatrix instead.

* Deprecated functions in fbxcompatibility.h file have been removed.

* The class FbxPointerGuard has been retired, because FbxAutoPtr and its
derivates replaces it.

* The function FbxArray::SetCount has been retired. Please use
FbxArray::Reserve or FbxArray::Resize instead.

* The function FbxArray::Empty is now deprecated. Please use
FbxArray::Clear instead.

* The function FbxArray::FindAfter is now deprecated. Please use
FbxArray::Find instead.

* The function FbxArray::FindBefore is now deprecated. Please use
FbxArray::FindReverse instead.

* The function FbxArray::AddMultiple is now deprecated. Please use
FbxArray::Grow instead.

* All functions in FbxObject, FbxProperty, FbxCollection and FbxDocument
that used to take a FbxClassId or an FBX_TYPE() macro, as the filtering
mechanism, are now deprecated. Please use the templated version of these
functions, such as: FbxObject::GetSrcObjectCount<Type>() or
FbxObject::GetSrcObject<Type>() The templated version returns the correct
type, so it is no longer needed to use FbxCast upon return of these
functions.

* All functions in FbxObject and FbxProperty that used to take a FbxClassId
plus an FbxCriteria have been retired instead of being deprecated,
because they didn't make sense from a logical standpoint, and can now
safely be replaced with the form Obj->Function<Type>(Criteria).

* The following functions have been made deprecated, and should be replaced
with their equivalent found in FbxObject:
FbxConnectSrc(Dst, Src) -> Dst->ConnectSrcObject(Src)
FbxConnectDst(Src, Dst) -> Src->ConnectDstObject(Dst)
FbxGetSrcCount(Obj) -> Obj->GetSrcCount()
FbxGetSrcCount(Obj, ClassId) -> Obj->GetSrcCount<Type>()
FbxGetSrc(Obj, Index) -> Obj->GetSrcObject(Index)
FbxGetSrc(Obj, Index, ClassId) -> Obj->GetSrcObject<Type>(Index)
FbxFindSrc(Obj, Name, Index) -> Obj->FindSrcObject(Name, Index)
FbxFindSrc(Obj, Name, ClassId, Index) -> Obj->FindSrcObject<Type>(Name, Index)
FbxDisconnectAllSrc(Obj) -> Obj->DisconnectAllSrcObject()
FbxGetDstCount(Obj) -> Obj->GetDstCount()
FbxGetDstCount(Obj, ClassId) -> Obj->GetDstCount<Type>()
FbxGetDst(Obj, Index) -> Obj->GetDstObject(Index)
FbxGetDst(Obj, Index, ClassId) -> Obj->GetDstObject<Type>(Index)
FbxFindDst(Obj, Name, Index) -> Obj->FindDstObject(Name, Index)
FbxFindDst(Obj, Name, ClassId, Index) -> Obj->FindDstObject<Type>(Name, Index)
FbxDisconnectAllDst(Obj) -> Obj->DisconnectAllDstObject()

* Fixed an issue with scaling inheritance not being computed properly by
the classic evaluator.

* The tangents and binormals generated by the FBX SDK will now be smoothed
according to the normal smoothing.

* Optimized tangents/binormals generation so that there not more of them
than there is normals on the mesh.

* The FBX SDK release version can now be safely linked into a debug app.

* Fixed a texture indice issue with old FBX 5.x content.

* Fixed a memory leak with runtime classes.

* The FBX SDK now uses the memory allocator in the FbxString class for all
allocations done by std::string.

* Changed the behavior of GetAnimationInterval so that it doesn't do a
union anymore. Now, the timespan parameter is always initialized properly
inside the function.

* Improved how the FBX SDK handle testing if file exist, resulting in a
faster file opening for missing assets that are over the network.

* Fixed a file crash when importing an FBX 5.x file without setting an IO
setting.

* Fix some issues with samples, as reported by users.

* Resolved issues with the memory allocator. For instance, FbxString now
use the specified memory allocator rather than the default STL allocator.

* Fixed a crash with a specific OBJ file.

* An issue with ResetPivotSetAndConvertAnimation breaking instanced mesh as
been corrected.

* Fixed multiple FBX Python SDK errors in samples.

* Fixed an issue with Collada export for meshes with multiple materials.

2013.1

* Renamed all classes with prefix "Fbx". Also renamed all structures with
the same prefix.

* Global functions and enumerations now start with the "Fbx" prefix.

* By default, the file fbxsdk_compatibility.h will be included when
including fbxsdk.h. This file defines a lot of the old class names to
help with the transition. However, if you want to use the new API, you
can define FBXSDK_NEW_API in your project and the compatibility file will
not be included, but will most likely result in a lot of errors to fix
in your application.

It is highly recommended that you start by fixing compilation errors
before defining FBXSDK_NEW_API in your project, but it is also highly
recommended to fully fix your code since the compatibility file might
be removed in a future release.

* Moved and renamed all enumerations into classes when possible.

* Moved files into appropriate folders, and grouped them.

* Removed KFbxMemoryAllocator class, instead use handlers setters functions
found in fbxalloc.h, such as FbxSetMallocHandler.

* Removed all KFCurveFilter classes, please use FbxAnimCurveFilter classes
instead.

* FbxFile is now exposed! See fbxfile.h for the list of available
functions.

* A new class, FbxFileUtils, now expose all static functions related to
file handling, such as remove or rename, etc.

* A new class, FbxPathUtils, now expose all static functions related to
file path handling, such as IsRelative or Clean, etc.

* Completely re-designed how Character Poses are stored in FBX.

* The FbxLight class has been augmented to support area lights and barn
doors.

* The FbxGeometryBase class has been augmented to support render options
such as PrimaryVisibility, CastShadow and ReceiveShadow.

* Many FBX SDK functions that were asking for file paths as inputs were
updated to support UTF-8. Their parameter names were updated to reflect
this change.

* It is now possible to retrieve the "long" version string of the FBX SDK
via the function FbxManager::GetVersion(true). This will allow developers
to get the version string of this library along with the name and the
revision number.

* Fixed various issues with sample codes.

* Now sample codes compile with warning level 4.

* Fixed an issue with animation evaluation that wasn't updated correctly
when told to.

* Fixed an issue with constraints being lost after export.

* Fixed an issue with animation evaluation sometimes returning twice the
value amount.

* Fixed an issue with RemovePolygon function on mesh class when mapping is
by polygon.

* Initial property values of LclTranslation, LclRotation and LclScaling
affect the evaluator's result when there are actually animation curves
connected to these properties. This has been corrected.

* Fixed an issue with writing cache data on Mac when a space was present
in the file path.

* Fixed a crash with xstring use in VS2010, caused by an assert.

* Improved precision in time and timecode classes.

* Changed how absolute and relative paths are handled during import. Now
if one of the two path is opening successfully, the other is changed to
work.

* Fixed an issue with the unroll animation filter.

* Now, when resampling animation, we move the default at the end rather
than at the start of the resampling.

2012.2

* Added Area Light support to KFbxLight class.

* Added Barn Doors support to KFbxLight class.

* HotSpot property on KFbxLight has been changed for InnerAngle.

* ConeAngle property on KFbxLight has been changed for OuterAngle.

* Various file I/O crashes.

* Duplicate material issue with material converter is fixed.

* Some minor fixes in sample codes.

* Fixed path issue in Collada reader.

* After writing FBX file, the scene should come back to its initial state.

* Fixed a crash on import of old scenes when it didn't contain blendshapes
or morpher data.

* Fixed issue with incorrect normals when converting from OBJ to FBX.

* Sample code "Cube Creator" was modifying the scene when exporting in OBJ,
This has been fixed.

* Fixed an issue with absolute versus relative file paths; now if one of them
is valid and the other is not, we fix the broken one.

* Fixed an issue with cache writing on Mac when there was a space in the file
name.

* Fixed an issue with the FBX exporter that would duplicate materials in very
specific conditions.

* After writing an FBX 6.x file with shapes, the scene was modified and data
was potentially lost. This has been corrected.

* Fixed an assert caused by stl string in VS2010.

* We now open FBX files in read-only mode rather than read+write. This allow
for other process to access the FBX file in parallel.

2012.1

* Added support for Image Sequences into KFbxVideo.

* Improved the reference documentation quite substantially.

* Refined how visibility inheritance works: added a new property for each
