Public Member Functions

 Graphic3d_TextureEnv (const TCollection_AsciiString &theFileName)
 Creates an environment texture from a file. More...
 
 Graphic3d_TextureEnv (const Graphic3d_NameOfTextureEnv theName)
 Creates an environment texture from a predefined texture name set. More...
 
 Graphic3d_TextureEnv (const Handle< Image_PixMap > &thePixMap)
 Creates an environment texture from the pixmap. More...
 
Graphic3d_NameOfTextureEnv Name () const
 Returns the name of the predefined textures or NOT_ENV_UNKNOWN when the name is given as a filename. More...
 
- Public Member Functions inherited from Graphic3d_TextureRoot
 ~Graphic3d_TextureRoot ()
 Destructor. More...
 
virtual Standard_Boolean IsDone () const
 Checks if a texture class is valid or not. More...
 
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. More...
 
Graphic3d_TypeOfTexture Type () const
 
const TCollection_AsciiStringGetId () const
 This ID will be used to manage resource in graphic driver. More...
 
Standard_Size Revision () const
 Return image revision. More...
 
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). More...
 
virtual Handle< Image_PixMapGetImage () const
 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())! More...

 Standard_Transient ()
 Empty constructor. More...

 Copy constructor – does nothing. More...

Standard_Boolean 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. More...
 
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. More...
 
Standard_TransientThis () 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. More...

 Get the reference counter of this object. More...
 
void IncrementRefCounter () const
 Increments the reference counter of this object. More...
