Detailed Description

       The SoIndexedTriangleStripSet class keeps data for rendering and otherwise representing
       triangle strips.

       Use nodes of this type as an effective way of drawing triangles which are strung together.

       For more information, see the documentation of the SoTriangleStripSet node.

       To render several strips within the same node, just separate the coordinate indices with
       -1. For more information about indexed shapes, see documentation in SoIndexedShape and
       SoIndexedFaceSet.

       Example scene graph:

       #Inventor V2.1 ascii

       Separator {
          Coordinate3 {
             point [
              -2 1 0, -1 -1 0, 0 1 0, 1 -1 0, 2 1 0, # first strip, z==0
              -2 1 5, -1 -1 5, 0 1 5, 1 -1 5, 2 1 5  # second strip, z==5
             ]
          }

          IndexedTriangleStripSet {
             coordIndex [
              0, 1, 2, 3, 4, -1,
              5, 6, 7, 8, 9, -1
             ]
          }
       }

       FILE FORMAT/DEFAULTS:

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

Constructor & Destructor Documentation

   SoIndexedTriangleStripSet::SoIndexedTriangleStripSet (void)
       Constructor. Default field values will equal those set in the SoIndexedShape parent class.

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

Member Function Documentation

   SoType SoIndexedTriangleStripSet::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 * SoIndexedTriangleStripSet::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 SoIndexedTriangleStripSet::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 SoIndexedTriangleStripSet::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.

   SbBool SoIndexedTriangleStripSet::generateDefaultNormals (SoState *state, SoNormalBundle
       *bundle) [virtual]
       This API member is considered internal to the library, as it is not likely to be of
       interest to the application programmer.

       Subclasses should override this method to generate default normals using the
       SoNormalBundle class. TRUE should be returned if normals were generated, FALSE otherwise.

       Default method returns FALSE.

       This function is an extension for Coin, and it is not available in the original SGI Open
       Inventor v2.1 API.

       Reimplemented from SoVertexShape.

   SbBool SoIndexedTriangleStripSet::generateDefaultNormals (SoState *state, SoNormalCache
       *cache) [protected],  [virtual]
       This API member is considered internal to the library, as it is not likely to be of
       interest to the application programmer.

       Subclasses should override this method to generate default normals using the SoNormalCache
       class. This is more effective than using SoNormalGenerator. Return TRUE if normals were
       generated, FALSE otherwise.

       Default method just returns FALSE.

       This function is an extension for Coin, and it is not available in the original SGI Open
       Inventor v2.1 API.

       Reimplemented from SoVertexShape.

   void SoIndexedTriangleStripSet::generatePrimitives (SoAction *action) [protected],  [virtual]
       The method implements action behavior for shape nodes for SoCallbackAction. It is invoked
       from SoShape::callback(). (Subclasses should not override SoNode::callback().)

       The subclass implementations uses the convenience methods SoShape::beginShape(),
       SoShape::shapeVertex(), and SoShape::endShape(), with SoDetail instances, to pass the
       primitives making up the shape back to the caller.

       Implements SoShape.
