Detailed Description

The SoShapeSimplifyAction class replaces complex primitives with simplified polygon representations.

Constructor & Destructor Documentation

SoShapeSimplifyAction::SoShapeSimplifyAction (void)

A constructor.

SoShapeSimplifyAction::~SoShapeSimplifyAction (void)\fC [virtual]\fP

The destructor.

Member Function Documentation

\fBSoType\fP SoShapeSimplifyAction::getTypeId (void) const\fC [virtual]\fP

Returns the type identification of an action derived from a class inheriting SoAction. This is used for run-time type checking and 'downward' casting.

Usage example:

void bar(SoAction * action)
{
  if (action->getTypeId() == SoGLRenderAction::getClassTypeId()) {
    // safe downward cast, know the type
    SoGLRenderAction * glrender = (SoGLRenderAction *)action;
  }
  return; // ignore if not renderaction
}

For application programmers wanting to extend the library with new actions: 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/SoSubAction.h: SO_ACTION_SOURCE, SO_ACTION_INIT_CLASS and SO_ACTION_CONSTRUCTOR.

For more information on writing Coin extensions, see the SoAction class documentation.

Returns the actual type id of an object derived from a class inheriting SoAction. Needs to be overridden in all subclasses.

Reimplemented from SoSimplifyAction.

void SoShapeSimplifyAction::addMethod (const \fBSoType\fPtype, SoActionMethodmethod)\fC [static]\fP

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

void SoShapeSimplifyAction::enableElement (const \fBSoType\fPtype, const intstackindex)\fC [static]\fP

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

const \fBSoEnabledElementsList\fP & SoShapeSimplifyAction::getEnabledElements (void) const\fC [protected]\fP, \fC [virtual]\fP

Returns a list of the elements used by action instances of this class upon traversal operations.

Reimplemented from SoSimplifyAction.

void SoShapeSimplifyAction::beginTraversal (\fBSoNode\fP *node)\fC [protected]\fP, \fC [virtual]\fP

This virtual method is called from SoAction::apply(), and is the entry point for the actual scenegraph traversal.

It can be overridden to initialize the action at traversal start, for specific initializations in the action subclasses inheriting SoAction.

Default method just calls traverse(), which any overridden implementation of the method must do too (or call SoAction::beginTraversal()) to trigger the scenegraph traversal.

Reimplemented from SoSimplifyAction.
