NAME

       SoTexture3Transform -

       The SoTexture3Transform class is used to define 3D texture transformations.

       Textures applied to shapes in the scene can be transformed by 'prefixing' in the state with instances of
       this node type. Translations, rotations and scaling in 3D can all be done.

Detailed Description

       The SoTexture3Transform class is used to define 3D texture transformations.

       Textures applied to shapes in the scene can be transformed by 'prefixing' in the state with instances of
       this node type. Translations, rotations and scaling in 3D can all be done.

       The default settings of this node's fields equals a 'null transform', ie no transformation.

       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:

       Texture3Transform {
           translation 0 0 0
           rotation 0 0 1  0
           scaleFactor 1 1 1
           scaleOrientation 0 0 1  0
           center 0 0 0
       }

       Destructor.

Member Function Documentation

   SoType SoTexture3Transform::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 * SoTexture3Transform::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 SoTexture3Transform::doAction (SoAction *action) [virtual]
       This function performs the typical operation of a node for any action.

       Reimplemented from SoNode.

   void SoTexture3Transform::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 SoTexture3Transform::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 SoTexture3Transform::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 SoTexture3Transform::pick (SoPickAction *action) [virtual]
       Action method for SoPickAction.

       Does common processing for SoPickAction action instances.

       Reimplemented from SoNode.

Member Data Documentation

   SoSFVec3f SoTexture3Transform::translation
       Texture coordinate translation. Default value is [0, 0, 0].

   SoSFRotation SoTexture3Transform::rotation
       Texture coordinate rotation (s is x-axis, t is y-axis and r is z-axis). Defaults to an identity rotation
       (ie zero rotation).

   SoSFVec3f SoTexture3Transform::scaleFactor
       Texture coordinate scale factors. Default value is [1, 1, 1].

   SoSFRotation SoTexture3Transform::scaleOrientation
       The orientation the texture is set to before scaling. Defaults to an identity rotation (ie zero
       rotation).

   SoSFVec3f SoTexture3Transform::center
       Center for scale and rotation. Default value is [0, 0, 0].
