NAME

       SoNonIndexedShape -

       The SoNonIndexedShape class is the superclass for all non-indexed vertex based shapes.

       It contains the (now obsoleted) startIndex field and a convenience method for calculating the bounding
       box.

SYNOPSIS

           Returns the type identification of an object derived from a class inheriting SoBase. This is used for
           run-time type checking and 'downward' casting.

Detailed Description

       The SoNonIndexedShape class is the superclass for all non-indexed vertex based shapes.

       It contains the (now obsoleted) startIndex field and a convenience method for calculating the bounding
       box.

Constructor & Destructor Documentation

   SoNonIndexedShape::SoNonIndexedShape (void) [protected]
       Constructor.

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

Member Function Documentation

   SoType SoNonIndexedShape::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 SoVertexShape.

       Reimplemented in SoFaceSet, SoLineSet, SoMarkerSet, SoPointSet, SoQuadMesh, and SoTriangleStripSet.

   const SoFieldData * SoNonIndexedShape::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 SoVertexShape.

       Reimplemented in SoFaceSet, SoLineSet, SoMarkerSet, SoPointSet, SoQuadMesh, and SoTriangleStripSet.

   void SoNonIndexedShape::computeCoordBBox (SoAction *action, intnumVertices, SbBox3f &box, SbVec3f &center)
       [protected]
       This method is provided as a convenient means for the subclasses of this class to find their bounding box
       and center value.

       The returned bounding box will enclose all vertices from startIndex up to startIndex + numVertices. If
       numVertices is less than zero, all vertices in the current coordinate element or vertex property node
       will be used in the calculation.

       The center point will be calculated as the average of all the vertices in the bounding box.

   void SoNonIndexedShape::fixNumVerticesPointers (SoState *state, const int32_t *&start, const int32_t *&end,
       int32_t *dummyarray) const [protected]
       Convenience method that might adjust start and end pointers, which should point at the start and end of
       the numVertices array when calling this method. This takes care of the case where numVertices contains a
       single -1, and all coordinates in the state (or in the vertexProperty field) should be rendered as one
       primitive.

       dummyarray should be a temporary array, with room for one integer.

       Not part of the OIV API.

Member Data Documentation

   SoSFInt32 SoNonIndexedShape::startIndex
       Coordinates are fetched from this index on. This field is now obsoleted, and is provided only for
       backward compatibility.
