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.
