NAME

       SoIndexedMarkerSet -

       The SoIndexedMarkerSet class is used to display a set of bitmap markers at 3D positions.

       This node either uses the coordinates currently on the state (typically set up by a
       leading SoCoordinate3 node in the scenegraph) or from a SoVertexProperty node attached to
       this node to render a set of 3D points.

Detailed Description

       The SoIndexedMarkerSet class is used to display a set of bitmap markers at 3D positions.

       This node either uses the coordinates currently on the state (typically set up by a
       leading SoCoordinate3 node in the scenegraph) or from a SoVertexProperty node attached to
       this node to render a set of 3D points.

       To add new markers, use the static functions in SoMarkerSet.

       Here's a simple usage example of SoIndexedMarkerSet in a scenegraph:

       #Inventor V2.1 ascii

       Separator {
          Material {
             diffuseColor [
              1 0 0, 0 1 0, 0 0 1, 1 1 0, 1 0 1, 1 1 1, 1 0.8 0.6, 0.6 0.8 1
             ]
          }
          MaterialBinding { value PER_VERTEX_INDEXED }

          Coordinate3 {
             point [
              -1 1 0, -1 -1 0, 1 -1 0, 1 1 0, 0 2 -1, -2 0 -1, 0 -2 -1, 2 0 -1
             ]
          }

          IndexedMarkerSet {
             coordIndex [0, 1, 2, 3, 4, 5, 6, 7]
             markerIndex [0, 1, 0, 1, 0, 1, 0, 1]
          }
       }.fi

       FILE FORMAT/DEFAULTS:

       IndexedMarkerSet {
         vertexProperty        NULL
         coordIndex        0
         materialIndex        -1
         normalIndex        -1
         textureCoordIndex        -1
         markerIndex   -1
       }

       Destructor.

Member Function Documentation

   SoType SoIndexedMarkerSet::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.

       Reimplemented from SoIndexedPointSet.

   const SoFieldData * SoIndexedMarkerSet::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 SoIndexedPointSet.

   void SoIndexedMarkerSet::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 SoIndexedPointSet.
