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_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. | |
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_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. | |
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())! | |
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. | |
Standard_Boolean | HasMipmaps () const |
Returns whether mipmaps should be generated or not. | |
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_Boolean | IsKind (const Standard_CString theTypeName) const |

Standard_Transient * | This () const |
