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.
