NAME

       SoBumpMapCoordinate -

       The SoBumpMapCoordinate class is a node for providing bump map
       coordinates to shape nodes.

       When encountering nodes of this type during traversal, the coordinates
       it contains will be put on the state stack for later use by shape
       nodes. The bump map coordinates can be used to specify explicit
       coordinates for a bump map. The SoBumpMap node is used to specify a
       bump map for the shape nodes.

Detailed Description

       The SoBumpMapCoordinate class is a node for providing bump map
       coordinates to shape nodes.

       When encountering nodes of this type during traversal, the coordinates
       it contains will be put on the state stack for later use by shape
       nodes. The bump map coordinates can be used to specify explicit
       coordinates for a bump map. The SoBumpMap node is used to specify a
       bump map for the shape nodes.

       Note that an SoBumpMapCoordinate node will replace the bump map
       coordinates already present in the state (if any).

       Also note that since the indexed shape nodes have no bumpMapCoordIndex
       field, the textureCoordIndex field will be used for selecting bump map
       coordinate indices. You can set the bump map coordinate binding using
       the SoTextureCoordinateBinding node. Bump map coordinates must
       therefore have the same binding as the texture coordinates for texture
       unit 0.

       If you supply no bump map coordinates for a shape, the texture
       coordinates for texture unit 0 will be used.

       FILE FORMAT/DEFAULTS:

           BumpMapCoordinate {
               point [  ]
           }

Member Function Documentation

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

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

       Reimplemented from SoNode.
