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.

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 () [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.
