DESCRIPTION

       This  node  is  the  abstract  base class for all profile nodes, which define 2D curves. A
       profile is not itself geometry, but is used to change or delimit the geometry of something
       else.  For  an  SoText3 node, the profile determines the cross-section of the side of each
       text character. For an SoNurbsSurface node, the profile is used to specify trim curves for
       the surface.

       The  current  profile state can consist of one or more profiles, each of which can be made
       up of one or more instances of SoProfile subclass nodes. Each profile node  specifies  (in
       the  index  field)  a set of indices that refer to the current set of profile coordinates,
       specified using either an SoProfileCoordinate2 or an SoProfileCoordinate3 node. No profile
       curve should intersect itself or another profile curve.

       Profiles  are  part  of  the  state,  just like all other properties. The state contains a
       current list of profiles.  Depending on the linkage field, a profile can  clear  the  list
       and  begin  a new profile, begin a new profile at the end of those already in the list, or
       append to the last profile in the current list. Note that when appending profile B to  the
       end of profile A, B must begin at the same 2D point at which A ends.

FIELDS

     SoMFInt32           index
          Indices into profile coordinates.

     SoSFEnum            linkage
          Specifies  connectivity  of  profile  curve with respect to profiles in current list in
          state.

METHODS

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

ACTION BEHAVIOR

       SoGLRenderAction, SoCallbackAction, SoGetBoundingBoxAction, SoRayPickAction
          Adds profile to current traversal state.
