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_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. More... | |
| Graphic3d_TypeOfTexture | Type () const |
| const TCollection_AsciiString & | GetId () 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_CompressedPixMap > | GetCompressedImage (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. More... | |
| virtual Handle< Image_PixMap > | GetImage (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())! More... | |
| const Handle< Graphic3d_TextureParams > & | GetParams () const |
| Standard_Boolean | IsColorMap () const |
| Return flag indicating color nature of values within the texture; TRUE by default. More... | |

| Set flag indicating color nature of values within the texture. More... | |
| Standard_Boolean | IsTopDown () const |
| Returns whether row's memory layout is top-down. More... | |

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

| Assignment operator, needed to avoid copying reference counter. More... | |
| virtual | ~Standard_Transient () |
| Destructor must be virtual. More... | |

| Memory deallocator for transient classes. More... | |
| virtual const opencascade::handle< Standard_Type > & | DynamicType () const |
| Returns a type descriptor about this object. More... | |

| Returns a true value if this is an instance of Type. More... | |

| Returns a true value if this is an instance of TypeName. 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_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. More... | |

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