Public Member Functions

 Graphic3d_Texture2D (const TCollection_AsciiString &theFileName)
 Creates a texture from a file. MipMaps levels will be automatically generated if needed.
 
 Graphic3d_Texture2D (const Graphic3d_NameOfTexture2D theNOT)
 Creates a texture from a predefined texture name set. MipMaps levels will be automatically generated if needed.
 
 Graphic3d_Texture2D (const Handle< Image_PixMap > &thePixMap)
 Creates a texture from the pixmap. MipMaps levels will be automatically generated if needed.
 
Graphic3d_NameOfTexture2D Name () const
 Returns the name of the predefined textures or NOT_2D_UNKNOWN when the name is given as a filename.
 
void SetImage (const Handle< Image_PixMap > &thePixMap)
 Assign new image to the texture. Note that this method does not invalidate already uploaded resources - consider calling UpdateRevision() if needed.
 
- Public Member Functions inherited from Graphic3d_TextureMap
void EnableSmooth ()
 enable texture smoothing
 
Standard_Boolean 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.
 
Standard_Boolean 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.
 
Standard_Boolean 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 ()
 Destructor.
 
virtual Standard_Boolean IsDone () const
 Checks if a texture class is valid or not.
 
const OSD_PathPath () 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_AsciiStringGetId () const
 This ID will be used to manage resource in graphic driver.
 
Standard_Size 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 Handle< Image_CompressedPixMapGetCompressedImage (const 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 Handle< Image_PixMapGetImage (const 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 Handle< Graphic3d_TextureParams > & GetParams () const
 
Standard_Boolean IsColorMap () const
 Return flag indicating color nature of values within the texture; TRUE by default.
 
void SetColorMap (Standard_Boolean theIsColor)
 Set flag indicating color nature of values within the texture.

void SetMipmapsGeneration (Standard_Boolean theToGenerateMipmaps)
 Sets whether to generate mipmaps or not.
 
Standard_Boolean IsTopDown () const
 Returns whether row's memory layout is top-down.

 Standard_Transient (const Standard_Transient &)
 Copy constructor – does nothing.
 
Standard_Transientoperator= (const Standard_Transient &)
 Assignment operator, needed to avoid copying reference counter.

Standard_Boolean IsKind (const Standard_CString 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_TransientThis () const

Standard_Integer GetRefCount () const noexcept
 Get the reference counter of this object.
 
void IncrementRefCounter () noexcept
 Increments the reference counter of this object.
