NAME
       SoFaceDetail — stores detail information about vertex-based shapes made of faces


INHERITS FROM
       SoDetail > SoFaceDetail


SYNOPSIS
       #include <Inventor/details/SoFaceDetail.h>

          Methods from class SoFaceDetail:

                            SoFaceDetail()
     virtual                ~SoFaceDetail()
     long                   getNumPoints() const
     const SoPointDetail *  getPoint(int i) const
     int32_t                getFaceIndex() const
     int32_t                getPartIndex() const
     static SoType          getClassTypeId()

          Methods from class SoDetail:

     SoDetail *          copy() const
     virtual SoType      getTypeId() const
     SbBool              isOfType(SoType type) const


DESCRIPTION
       This class contains detail information about a point on a face in a vertex-based shape made of faces. The
       information includes the number of points in the face, the points forming the vertices of the  face,  and
       the index of the face within the shape.

       Note  that  when  an SoFaceDetail is returned from picking (in an SoPickedPoint), it will contain details
       for all points defining the face that was intersected. However, when an SoFaceDetail  is  created  for  a
       triangle produced during primitive generation (in an SoPrimitiveVertex), it will contain details for only
       the three vertices of the triangle.


METHODS
                            SoFaceDetail()
     virtual                ~SoFaceDetail()
          Constructor and destructor.

     long                   getNumPoints() const
          Returns the number of points in the face.

     const SoPointDetail *  getPoint(int i) const
          Returns information about  the  point  forming  the  i'th  vertex  of  the  face,  represented  as  an
          SoPointDetail.

     int32_t                getFaceIndex() const
          Returns the index of the face within the shape.

     int32_t                getPartIndex() const
          Returns the index of the part containing the face within the shape.

     static SoType          getClassTypeId()
          Returns type identifier for this class.
