Detailed Description

Performs a generic traversal of a scene graph or path.

Performs a generic traversal of a scene graph or path. In many cases a "custom" action can be implemented using SoCallbackAction with much less complexity than deriving a completely new action class.

The application can specify callback methods that will be called when the action traverses a node of the specified class or a derived class. For example a callback for the SoCone class will only be called for SoCone nodes, but a callback for the SoShape class will be called for any type of shape node.

This makes SoCallbackAction flexible and very convenient for "visiting" a set of nodes, especially when you only need the node itself and not a path to the node. For example, to count all the shapes in the scene graph. It is possible to get the path to the node being visited (see getCurPath() ), but SoSearchAction may be more convenient for getting a path to one or a small number of nodes.

In addition, callback methods can be registered to collect the primitives (trangles, lines and points) generated by shapes in the scene graph. These primitives are the actual geometry if the shape contains triangles, lines or points, else they represent or approximate the actual geometry. NOTE: Most, but not all, shapes can generate primitives. See below for a complete list. Triangle primitives are used for all surfaces (such as cubes, face sets, or 3D text), line segment primitives are used for line shapes, and point primitives are used for point shapes. Note that the type of primitives generated for a shape is the same, regardless of drawing style or other properties.

Most of the methods on this class access information from the traversal state. They should be called only by callback functions that are invoked during traversal, so there is a valid state to work with.

EXAMPLE

SoCallbackAction action;
action.addPreCallback     ( SoShape::getClassTypeId(), NodeCallback, NULL );
action.addTriangleCallback( SoShape::getClassTypeId(), TriangleCallback, NULL );
action.apply( root );

This method will be called for each shape node in the scene graph.

SoCallbackAction::Response
NodeCallback( void*, SoCallbackAction*, const SoNode* node)
{
  // Print node's name (if any) and class name
  std::cout << "Shape \"" << node->getName().getString() << "\": "
            << node->getTypeId().getName().getString()
            << std::endl;
   return SoCallbackAction::CONTINUE;
}

This method will be called for each triangle in the shape node.

// This method will be called for each triangle in the shape node.
void TriangleCallback( void*, SoCallbackAction*,
                       const SoPrimitiveVertex *vertex1,
                       const SoPrimitiveVertex *vertex2,
                       const SoPrimitiveVertex *vertex3)
{
   std::cout << "  Triangle:\n";
   printVertex( vertex1, "1" );
   printVertex( vertex2, "2" );
   printVertex( vertex3, "3" );
}
 
void
printVertex( const SoPrimitiveVertex *vertex, const char* label )
{
   const SbVec3f& point = vertex->getPoint();
   std::cout << "    Vert" << label << " = " << point << std::endl;
}

Example output:

Shape "": SoCone
  Triangle:
    Vert1 = 0.0, -1.0, -1.0
    Vert2 = 0.0, 1.0, -0.0
    Vert3 = 0.38268346, -1.0, -0.9238795
  Triangle:
    Vert1 = 0.38268346, -1.0, -0.9238795
    Vert2 = 0.0, 1.0, -0.0
    Vert3 = 0.0, 1.0, -0.0
