NAME

       SoPointDetail -

       The SoPointDetail class is for storing detailed information for a single 3D point.

       Instances of this class are used among other things for storing information about the
       vertices of lines and polygons after pick operations, and for storing information returned
       to tessellation callbacks.

Detailed Description

       The SoPointDetail class is for storing detailed information for a single 3D point.

       Instances of this class are used among other things for storing information about the
       vertices of lines and polygons after pick operations, and for storing information returned
       to tessellation callbacks.

       It contains indices into the vertex coordinate sets, along with indices into material,
       texture and normal coordinates for the point.

Constructor & Destructor Documentation

   SoPointDetail::SoPointDetail (void)
       Sets up an empty detail instance (all indices are equal to 0).

   SoPointDetail::~SoPointDetail () [virtual]
       Destructor.

Member Function Documentation

   SoType SoPointDetail::getTypeId (void) const [virtual]
       Returns the type identification of a detail derived from a class inheriting SoDetail. This
       is used for run-time type checking and 'downward' casting.

       Usage example:

       void fuhbear(SoDetail * detail)
       {
         if (detail->getTypeId() == SoFaceDetail::getClassTypeId()) {
           // safe downward cast, know the type
           SoFaceDetail * facedetail = (SoFaceDetail *)detail;
         }
         return; // ignore if not a SoFaceDetail
       }

       For application programmers wanting to extend the library with new detail classes: 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 Inventor/nodes/SoSubDetail.h: SO_DETAIL_SOURCE and
       SO_DETAIL_INIT_CLASS.

       Implements SoDetail.

   SoDetail * SoPointDetail::copy (void) const [virtual]
       Return a deep copy of ourself.

       Note that if the Coin library has been built as a DLL under Microsoft Windows and you use
       this method from application code, you must make sure that both the Coin DLL and the
       application executable is using the same instance of a C Run-Time (CRT) library.
       Otherwise, you will get memory heap corruption upon deallocating the returned instances,
       eventually leading to mysterious crashes.

       Implements SoDetail.

   int SoPointDetail::getCoordinateIndex (void) const
       Returns index into coordinate set for the point's 3D coordinates.

   int SoPointDetail::getMaterialIndex (void) const
       Returns point's index into set of materials.

   int SoPointDetail::getNormalIndex (void) const
       Returns point's index into set of normals.

   int SoPointDetail::getTextureCoordIndex (void) const
       Returns point's index into set of texture coordinates.

   void SoPointDetail::setCoordinateIndex (const intidx)
       Used by client code for initializing the point detail instance.

   void SoPointDetail::setMaterialIndex (const intidx)
       Used by client code for initializing the point detail instance.

   void SoPointDetail::setNormalIndex (const intidx)
       Used by client code for initializing the point detail instance.

   void SoPointDetail::setTextureCoordIndex (const intidx)
       Used by client code for initializing the point detail instance.
