Public Member Functions
	RWMesh_MaterialMap (const TCollection_AsciiString &theFile)
	Main constructor.

	~RWMesh_MaterialMap () override

const XCAFPrs_Style &	DefaultStyle () const
	Return default material definition to be used for nodes with only color defined.

void	SetDefaultStyle (const XCAFPrs_Style &theStyle)
	Set default material definition to be used for nodes with only color defined.

TCollection_AsciiString	FindMaterial (const XCAFPrs_Style &theStyle) const
	Find already registered material.

virtual TCollection_AsciiString	AddMaterial (const XCAFPrs_Style &theStyle)
	Register material and return its name identifier.

virtual bool	CreateTextureFolder ()
	Create texture folder "modelName/textures"; for example: MODEL: Path/ModelName.gltf IMAGES: Path/ModelName/textures/ Warning! Output folder is NOT cleared.

virtual bool	CopyTexture (TCollection_AsciiString &theResTexture, const occ::handle< Image_Texture > &theTexture, const TCollection_AsciiString &theKey)

	Return failed flag.

Public Member Functions inherited from Standard_Transient
	Standard_Transient ()
	Empty constructor.

	Standard_Transient (const Standard_Transient &)
	Copy constructor – does nothing.

Standard_Transient &	operator= (const Standard_Transient &)
	Assignment operator, needed to avoid copying reference counter.

virtual	~Standard_Transient ()=default
	Destructor must be virtual.

virtual const opencascade::handle< Standard_Type > &	DynamicType () const
	Returns a type descriptor about this object.

bool	IsInstance (const opencascade::handle< Standard_Type > &theType) const
	Returns a true value if this is an instance of Type.

bool	IsInstance (const char *const theTypeName) const
	Returns a true value if this is an instance of TypeName.

bool	IsKind (const opencascade::handle< Standard_Type > &theType) const
	Returns true if this is an instance of Type or an instance of any class that inherits from Type. Note that multiple inheritance is not supported by OCCT RTTI mechanism.

bool	IsKind (const char *const theTypeName) const
	Returns true if this is an instance of TypeName or an instance of any class that inherits from TypeName. Note that multiple inheritance is not supported by OCCT RTTI mechanism.

Standard_Transient *	This () const
	Returns non-const pointer to this object (like const_cast). For protection against creating handle to objects allocated in stack or call from constructor, it will raise exception Standard_ProgramError if reference counter is zero.

int	GetRefCount () const noexcept
	Get the reference counter of this object.

void	IncrementRefCounter () noexcept
	Increments the reference counter of this object. Uses relaxed memory ordering since incrementing only requires atomicity, not synchronization with other memory operations.

int	DecrementRefCounter () noexcept
	Decrements the reference counter of this object; returns the decremented value. Uses release ordering for the decrement to ensure all writes to the object are visible before the count reaches zero. An acquire fence is added only when the count reaches zero, ensuring proper synchronization before deletion. This is more efficient than using acq_rel for every decrement.

virtual void	Delete () const
	Memory deallocator for transient classes.

Static Protected Member Functions
static bool	copyFileTo (const TCollection_AsciiString &theFileSrc, const TCollection_AsciiString &theFileDst)
	Copy file to another place.

	output folder for images (full path)

	output folder for images (short path)

TCollection_AsciiString	myFileName
	output glTF file path

TCollection_AsciiString	myShortFileNameBase
	output glTF file name without extension

TCollection_AsciiString	myKeyPrefix
	prefix for generated keys

NCollection_DoubleMap< XCAFPrs_Style, TCollection_AsciiString >	myStyles
	map of processed styles

NCollection_Map< occ::handle< Image_Texture > >	myImageFailMap
	map of images failed to be copied
