Public Member Functions
void	EnableSmooth ()
	enable texture smoothing

bool	IsSmoothed () const
	Returns TRUE if the texture is smoothed.

void	DisableSmooth ()
	disable texture smoothing

void	EnableModulate ()
	enable texture modulate mode. the image is modulate with the shading of the surface.

void	DisableModulate ()
	disable texture modulate mode. the image is directly decal on the surface.

bool	IsModulate () const
	Returns TRUE if the texture is modulate.

void	EnableRepeat ()
	use this methods if you want to enable texture repetition on your objects.

void	DisableRepeat ()
	use this methods if you want to disable texture repetition on your objects.

bool	IsRepeat () const
	Returns TRUE if the texture repeat is enable.

Graphic3d_LevelOfTextureAnisotropy	AnisoFilter () const

void	SetAnisoFilter (const Graphic3d_LevelOfTextureAnisotropy theLevel)

Public Member Functions inherited from Graphic3d_TextureRoot
	~Graphic3d_TextureRoot () override
	Destructor.

virtual bool	IsDone () const
	Checks if a texture class is valid or not.

const OSD_Path &	Path () const
	Returns the full path of the defined texture. It could be empty path if GetImage() is overridden to load image not from file.

Graphic3d_TypeOfTexture	Type () const

const TCollection_AsciiString &	GetId () const
	This ID will be used to manage resource in graphic driver.

size_t	Revision () const
	Return image revision.

void	UpdateRevision ()
	Update image revision. Can be used for signaling changes in the texture source (e.g. file update, pixmap update) without re-creating texture source itself (since unique id should be never modified).

virtual occ::handle< Image_CompressedPixMap >	GetCompressedImage (const occ::handle< Image_SupportedFormats > &theSupported)
	This method will be called by graphic driver each time when texture resource should be created. It is called in front of GetImage() for uploading compressed image formats natively supported by GPU.

virtual occ::handle< Image_PixMap >	GetImage (const occ::handle< Image_SupportedFormats > &theSupported)
	This method will be called by graphic driver each time when texture resource should be created. Default constructors allow defining the texture source as path to texture image or directly as pixmap. If the source is defined as path, then the image will be dynamically loaded when this method is called (and no copy will be preserved in this class instance). Inheritors may dynamically generate the image. Notice, image data should be in Bottom-Up order (see Image_PixMap::IsTopDown())!

const occ::handle< Graphic3d_TextureParams > &	GetParams () const

bool	IsColorMap () const
	Return flag indicating color nature of values within the texture; TRUE by default.

void	SetColorMap (bool theIsColor)
	Set flag indicating color nature of values within the texture.

bool	HasMipmaps () const
	Returns whether mipmaps should be generated or not.

void	SetMipmapsGeneration (bool theToGenerateMipmaps)
	Sets whether to generate mipmaps or not.

bool	IsTopDown () const
	Returns whether row's memory layout is top-down.

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.

Protected Member Functions
	Graphic3d_TextureMap (const TCollection_AsciiString &theFileName, const Graphic3d_TypeOfTexture theType)

	Graphic3d_TextureMap (const occ::handle< Image_PixMap > &thePixMap, const Graphic3d_TypeOfTexture theType)

Protected Member Functions inherited from Graphic3d_TextureRoot
	Graphic3d_TextureRoot (const TCollection_AsciiString &theFileName, const Graphic3d_TypeOfTexture theType)
	Creates a texture from a file Warning: Note that if <FileName> is NULL the texture must be realized using LoadTexture(image) method.

	Graphic3d_TextureRoot (const occ::handle< Image_PixMap > &thePixmap, const Graphic3d_TypeOfTexture theType)
	Creates a texture from pixmap. Please note that the implementation expects the image data to be in Bottom-Up order (see Image_PixMap::IsTopDown()).

void	generateId ()
	Unconditionally generate new texture id. Should be called only within constructor.

virtual occ::handle< Image_PixMap >	GetImage () const
	Method for supporting old API; another GetImage() method should be implemented instead.
