TDynamicAttributeBase

Base class for attributes that live on a dynamic mesh (or similar dynamic object)

API > API/Runtime > API/Runtime/GeometryCore

Base class for attributes that live on a dynamic mesh (or similar dynamic object)

Subclasses can override the On* functions to ensure the attribute remains up to date through changes to the dynamic object

Functions

Public

Name Remarks Include Path Unreal Specifiers

bool Append ( const TDynamicAttributeBase& Source,
const FDynamicMesh3::FAppendInfo& AppendInfo
)

 Add elements from the Source attribute, using the AppendInfo to determine the range to copy. DynamicMesh/DynamicAttribute.h  

void AppendDefaulted ( const FDynamicMesh3::FAppendInfo& AppendInfo
)

 Add default-valued elements, using the AppendInfo to determine the range to add. DynamicMesh/DynamicAttribute.h  

virtual bool CheckValidity ( bool bAllowNonmanifold,
EValidityCheckFailMode FailMode
) const

 Check validity of attribute DynamicMesh/DynamicAttribute.h  

void CompactInPlace ( const FCompactMaps& CompactMaps
)

bool CopyIn ( int RawID,
void* Buffer,
int BufferSize

bool CopyOut ( int RawID,
void* Buffer,
int BufferSize
) const

 Generic function to copy data out of an attribute; it's up to the derived class to map RawID to chunks of attribute data DynamicMesh/DynamicAttribute.h  

bool CopyThroughMapping ( const TDynamicAttributeBase* Source,
const FMeshIndexMappings& Mapping
)

 Copy data from a different attribute to this one, using the mesh index mapping to determine the correspondence DynamicMesh/DynamicAttribute.h  

virtual SIZE_T GetByteCount()

   DynamicMesh/DynamicAttribute.h  

FName GetName()

 Get optional identifier for this attribute set. DynamicMesh/DynamicAttribute.h  

virtual TDynamicAttributeBase * MakeCompactCopy ( const FCompactMaps& CompactMaps,

TDynamicAttributeBase * MakeCopy ( ParentType* ParentIn
) const

 Allocate a new copy of the attribute layer, optionally with a different parent DynamicMesh/DynamicAttribute.h  

TDynamicAttributeBase * MakeNew ( ParentType* ParentIn
