NAME

       SoLinearProfile -

       The SoLinearProfile class is a node for specifying linear profile curves.

       Use nodes of this type if you want to set up profiles that are simply straight lines
       connected by control points.

Detailed Description

       The SoLinearProfile class is a node for specifying linear profile curves.

       Use nodes of this type if you want to set up profiles that are simply straight lines
       connected by control points.

       FILE FORMAT/DEFAULTS:

       LinearProfile {
           index 0
           linkage START_FIRST
       }

Constructor & Destructor Documentation

   SoLinearProfile::SoLinearProfile (void)
       Constructor.

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

Member Function Documentation

   SoType SoLinearProfile::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 SoProfile.

   const SoFieldData * SoLinearProfile::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 SoProfile.

   void SoLinearProfile::getTrimCurve (SoState *state, int32_t &numpoints, float *&points, int
       &floatspervec, int32_t &numknots, float *&knotvector) [virtual]
       Return points and knotvector of the state.

       Implements SoProfile.

   void SoLinearProfile::getVertices (SoState *state, int32_t &numvertices, SbVec2f *&vertices)
       [virtual]
       Return vertex set of state.

       Implements SoProfile.
