NAME

       SoIndexedLineSet -

       The SoIndexedLineSet class is used to render and otherwise represent indexed lines.

       The indexed counterpart of SoLineSet. Lines can specified using indices for coordinates, normals,
       materials and texture coordinates.

Detailed Description

       The SoIndexedLineSet class is used to render and otherwise represent indexed lines.

       The indexed counterpart of SoLineSet. Lines can specified using indices for coordinates, normals,
       materials and texture coordinates.

       If no normals are supplied on the stack (or in the vertexProperty field), the lines will be rendered with
       lighting disabled.

       For more information about line sets, see documentation in SoLineSet. For more information about indexed
       shapes, see documentation in SoIndexedShape and SoIndexedFaceSet.

       FILE FORMAT/DEFAULTS:

       IndexedLineSet {
           vertexProperty NULL
           coordIndex 0
           materialIndex -1
           normalIndex -1
           textureCoordIndex -1
       }

Constructor & Destructor Documentation

   SoIndexedLineSet::SoIndexedLineSet (void)
       Constructor.

   SoIndexedLineSet::~SoIndexedLineSet () [protected],  [virtual]
       Destructor.

Member Function Documentation

   SoType SoIndexedLineSet::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 SoIndexedShape.

   const SoFieldData * SoIndexedLineSet::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 SoIndexedShape.

   void SoIndexedLineSet::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 SoShape.

   void SoIndexedLineSet::getBoundingBox (SoGetBoundingBoxAction *action) [virtual]
       Action method for the SoGetBoundingBoxAction.

       Calculates bounding box and center coordinates for node and modifies the values of the action to
       encompass the bounding box for this node and to shift the center point for the scene more towards the one
       for this node.

       Nodes influencing how geometry nodes calculates their bounding box also overrides this method to change
       the relevant state variables.

       Reimplemented from SoShape.

   void SoIndexedLineSet::getPrimitiveCount (SoGetPrimitiveCountAction *action) [virtual]
       Action method for the SoGetPrimitiveCountAction.

       Calculates the number of triangle, line segment and point primitives for the node and adds these to the
       counters of the action.

       Nodes influencing how geometry nodes calculates their primitive count also overrides this method to
       change the relevant state variables.

       Reimplemented from SoShape.

   void SoIndexedLineSet::notify (SoNotList *l) [protected],  [virtual]
       Notifies all auditors for this instance when changes are made.

       Reimplemented from SoVertexShape.
