Shape nodes within the scope of **SoTexture3** nodes in the scene graph (i.e. below the same **SoSeparator** and to the right hand side of the **SoTexture3**) will have the texture applied according to each shape type's individual characteristics. See the documentation of the various shape types (**SoFaceSet**, **SoCube**, **SoSphere**, etc.) for information about the specifics of how the textures will be applied. An **SoTexture3** node will override any previous encountered **SoTexture2** nodes and vice versa. Mixing of **SoTexture3** and **SoTextureCoordinate2** (or the other way around) is legal, but the third texture coordinate component will be ignored (set to 0.0). Be aware that this class is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.\ \ **FILE FORMAT/DEFAULTS:** ``` Texture3 { filenames "" images 0 0 0 0 wrapR REPEAT wrapS REPEAT wrapT REPEAT model MODULATE blendColor 0 0 0 enableCompressedTexture FALSE } ``` **Since** Coin 2.0 TGS Inventor 2.6 ## Member Enumeration Documentation ### enum SoTexture3::Model Texture mapping model. **Enumerator** - ***MODULATE*** Texture image is modulated with polygon. - ***DECAL*** Texture image overwrites polygon color. - ***BLEND*** Blend image using blendColor. ### enum SoTexture3::Wrap Enum used to specify wrapping strategy. **Enumerator** - ***REPEAT*** Repeat texture when coordinate is not between 0 and 1. - ***CLAMP*** Clamp coordinate between 0 and 1. ## Constructor & Destructor Documentation ### SoTexture3::SoTexture3 (void ) Constructor. ### SoTexture3::~SoTexture3 () \[protected\], \[virtual\] Destructor. ## Member Function Documentation ### SoType SoTexture3::getClassTypeId (void ) \[static\] This static method returns the **SoType** object associated with objects of this class. ### SoType SoTexture3::getTypeId (void ) const \[virtual\] Returns the type identification of an object derived from a class inheriting **SoBase**. This is used for runtime type checking and "downward" casting. Reimplemented from **SoTexture**. ### const SoFieldData \*\* SoTexture3::getFieldDataPtr (void ) \[static\], \[protected\] *This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.*\ Returns the **SoFieldData** class which holds information about fields in this node. ### const SoFieldData \* SoTexture3::getFieldData (void ) const \[protected\], \[virtual\] Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL. Reimplemented from **SoTexture**. ### void SoTexture3::doAction (SoAction \* action) \[virtual\] This function performs the typical operation of a node for any action. Reimplemented from **SoTexture**. ### void SoTexture3::GLRender (SoGLRenderAction \* action) \[virtual\] Action method for the **SoGLRenderAction**. This is called during rendering traversals. Nodes influencing the rendering state in any way or want to throw geometry primitives at OpenGL override this method. Reimplemented from **SoTexture**. ### void SoTexture3::callback (SoCallbackAction \* action) \[virtual\] Action method for **SoCallbackAction**. Simply updates the state according to how the node behaves for the render action, so the application programmer can use the **SoCallbackAction** for extracting information about the scene graph. Reimplemented from **SoTexture**. ### SbBool SoTexture3::readInstance (SoInput \* in, unsigned short flags) \[protected\], \[virtual\] This method is mainly intended for internal use during file import operations. It reads a definition of an instance from the input stream *in*. The input stream state points to the start of a serialized / persistent representation of an instance of this class type. TRUE or FALSE is returned, depending on if the instantiation and configuration of the new object of this class type went OK or not. The import process should be robust and handle corrupted input streams by returning FALSE. *flags* is used internally during binary import when reading user extension nodes, group nodes or engines. Reimplemented from **SoNode**. ### void SoTexture3::notify (SoNotList \* l) \[protected\], \[virtual\] Notifies all auditors for this instance when changes are made. Reimplemented from **SoNode**. ### int SoTexture3::getReadStatus (void ) \[protected\] Returns read status. 1 for success, 0 for failure. ### void SoTexture3::setReadStatus (int s) \[protected\] Sets read status. **See also** **getReadStatus()** ## Member Data Documentation ### SoMFString SoTexture3::filenames Texture filename(s). Specify either this or use **SoTexture3::images**, not both. The depth of the volume is specified by the number of filenames specified. All images must have the same dimensions and number of components. NB! A field sensor is attached to this field internally and reloads all images when this field changes. You must therefore be careful when setting this field and either use startEditing()/finishEditing() or set all values with one function call; setValues(). ### SoSFImage3 SoTexture3::images Inline image data. ### SoSFEnum SoTexture3::wrapR Wrapping strategy for the R coordinate (depth). ### SoSFEnum SoTexture3::wrapS Wrapping strategy for the S coordinate. ### SoSFEnum SoTexture3::wrapT Wrapping strategy for the T coordinate. ### SoSFEnum SoTexture3::model Texture model. ### SoSFColor SoTexture3::blendColor Blend color. Used when **SoTexture3::model** is **SoTexture3::BLEND**. ### SoSFBool SoTexture3::enableCompressedTexture Hint to Coin that compressed textures should be used if this is supported by the graphics hardware and OpenGL drivers. Using compressed textures usually reduces texture memory usage for a texture by 4-6 times. **Since** Coin 2.4.2 TGS Inventor 4.0 ## Author Generated automatically by Doxygen for Coin from the source code.
