class documentation is taken verbatim from the VRML97 standard (ISO/IEC 14772-1:1997). It is copyright The Web3D Consortium, and is used by permission of the Consortium:**\ ``` PixelTexture { exposedField SFImage image 0 0 0 # see SoSFImage field SFBool repeatS TRUE field SFBool repeatT TRUE } ``` The PixelTexture node defines a 2D image-based texture map as an explicit array of pixel values (image field) and parameters controlling tiling repetition of the texture onto geometry. Texture maps are defined in a 2D coordinate system (s, t) that ranges from 0.0 to 1.0 in both directions. The bottom edge of the pixel image corresponds to the S-axis of the texture map, and left edge of the pixel image corresponds to the T-axis of the texture map. The lower-left pixel of the pixel image corresponds to s=0.0, t=0.0, and the top-right pixel of the image corresponds to s = 1.0, t = 1.0. See 4.6.11, Texture maps (http://www.web3d.org/documents/specifications/14772/V2.0/part1/concepts.html#4.6.11), for a general description of texture maps. Figure 6.13 depicts an example PixelTexture. Figure 6.13 -- PixelTexture node See 4.14, Lighting model (http://www.web3d.org/documents/specifications/14772/V2.0/part1/concepts.html#4.14), for a description of how the texture values interact with the appearance of the geometry. **SoSFImage**, describes the specification of an image. The repeatS and repeatT fields specify how the texture wraps in the S and T directions. If repeatS is TRUE (the default), the texture map is repeated outside the 0-to-1 texture coordinate range in the S direction so that it fills the shape. If repeatS is FALSE, the texture coordinates are clamped in the S direction to lie within the 0.0 to 1.0 range. The repeatT field is analogous to the repeatS field. ## Constructor & Destructor Documentation ### SoVRMLPixelTexture::SoVRMLPixelTexture (void ) Constructor. ### SoVRMLPixelTexture::~SoVRMLPixelTexture () \[protected\], \[virtual\] Destructor. ## Member Function Documentation ### SoType SoVRMLPixelTexture::getClassTypeId (void ) \[static\] This static method returns the **SoType** object associated with objects of this class. ### SoType SoVRMLPixelTexture::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 **SoVRMLTexture**. ### const SoFieldData \*\* SoVRMLPixelTexture::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 \* SoVRMLPixelTexture::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 **SoVRMLTexture**. ### void SoVRMLPixelTexture::initClass (void ) \[static\] ### void SoVRMLPixelTexture::doAction (SoAction \* action) \[virtual\] This function performs the typical operation of a node for any action. Reimplemented from **SoNode**. ### void SoVRMLPixelTexture::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 **SoVRMLTexture**. ### void SoVRMLPixelTexture::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 **SoNode**. ### void SoVRMLPixelTexture::rayPick (SoRayPickAction \* action) \[virtual\] Action method for **SoRayPickAction**. Checks the ray specification of the *action* and tests for intersection with the data of the node. Nodes influencing relevant state variables for how picking is done also override this method. Reimplemented from **SoNode**. ### SbBool SoVRMLPixelTexture::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 SoVRMLPixelTexture::notify (SoNotList \* list) \[protected\], \[virtual\] Overloaded to detect when fields change. Reimplemented from **SoNode**. ## Author Generated automatically by Doxygen for Coin from the source code.
