NAME

       SoTextureMatrixTransform -

       The SoTextureMatrixTransform class is used to define a texture matrix transformation.

       Textures applied to shapes in the scene can be transformed by 'prefixing' in the state
       with instances of this node type.

Detailed Description

       The SoTextureMatrixTransform class is used to define a texture matrix transformation.

       Textures applied to shapes in the scene can be transformed by 'prefixing' in the state
       with instances of this node type.

       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:

       TextureMatrixTransform {
           matrix
             1 0 0 0
             0 1 0 0
             0 0 1 0
             0 0 0 1
       }

Member Function Documentation

   SoType SoTextureMatrixTransform::getTypeId (void) const [virtual]
       Returns the type identification of an object derived from a class inheriting SoBase. This
       is used for run-time type checking and 'downward' casting. Usage example:

       void foo(SoNode * node)
       {
         if (node->getTypeId() == SoFile::getClassTypeId()) {
           SoFile * filenode = (SoFile *)node;  // safe downward cast, knows the type
         }
       }

       For application programmers wanting to extend the library with new nodes, engines,
       nodekits, draggers or others: this method needs to be overridden in all subclasses. This
       is typically done as part of setting up the full type system for extension classes, which
       is usually accomplished by using the pre-defined macros available through for instance
       Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes),
       Inventor/engines/SoSubEngine.h (for engine classes) and so on.

       For more information on writing Coin extensions, see the class documentation of the
       toplevel superclasses for the various class groups.

       Implements SoBase.

   const SoFieldData * SoTextureMatrixTransform::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 SoFieldContainer.

   void SoTextureMatrixTransform::doAction (SoAction *action) [virtual]
       This function performs the typical operation of a node for any action.

       Reimplemented from SoNode.

   void SoTextureMatrixTransform::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 SoTextureMatrixTransform::GLRender (SoGLRenderAction *action) [virtual]
       Action method for the SoGLRenderAction.

       This is called during rendering traversals. Nodes influencing the rendering state in any
       way or who wants to throw geometry primitives at OpenGL overrides this method.

       Reimplemented from SoNode.

   void SoTextureMatrixTransform::getMatrix (SoGetMatrixAction *action) [virtual]
       Action method for SoGetMatrixAction.

       Updates action by accumulating with the transformation matrix of this node (if any).

       Reimplemented from SoNode.

   void SoTextureMatrixTransform::pick (SoPickAction *action) [virtual]
       Action method for SoPickAction.

       Does common processing for SoPickAction action instances.

       Reimplemented from SoNode.
