NAME

       SoBumpMapTransform -

       The SoBumpMapTransform class is used to define 2D bump map
       transformations.

       Bump maps 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 2D can all be done.

Detailed Description

       The SoBumpMapTransform class is used to define 2D bump map
       transformations.

       Bump maps 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 2D can all be done.

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

       FILE FORMAT/DEFAULTS:

           BumpMapTransform {
               translation 0 0
               rotation 0
               scaleFactor 1 1
               center 0 0
           }

Member Function Documentation

   void SoBumpMapTransform::initClass (void) [static] Sets up initialization
       for data common to all instances of this class, like submitting
       necessary information to the Coin type system.
       Reimplemented from SoNode.

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

   void SoBumpMapTransform::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 SoBumpMapTransform::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 SoBumpMapTransform::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 SoBumpMapTransform::pick (SoPickAction * action) [virtual] Action
       method for SoPickAction.
       Does common processing for SoPickAction action instances.

       Reimplemented from SoNode.

Member Data Documentation

   SoSFVec2f SoBumpMapTransform::translation Texture coordinate translation.
       Default value is [0, 0].
   SoSFFloat SoBumpMapTransform::rotation Texture coordinate rotation (around
       z-axis, s is x-axis and t is y-axis). Defaults to an identity rotation
       (ie zero rotation).
   SoSFVec2f SoBumpMapTransform::scaleFactor Texture coordinate scale factors.
       Default value is [1, 1].
   SoSFVec2f SoBumpMapTransform::center Center for scale and rotation. Default
       value is [0, 0].
