Note. This is work-in-progress. pederb, 2005-04-05. The code below is an example of a program that applies an **SoReorganizeAction** on a scene graph, converting all shapes into shapes that can be rendered using vertex array or VBO rendering. ``` #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include static void strip_node(SoType type, SoNode * root) { SoSearchAction sa; sa.setType(type); sa.setSearchingAll(TRUE); sa.setInterest(SoSearchAction::ALL); sa.apply(root); SoPathList & pl = sa.getPaths(); for (int i = 0; i < pl.getLength(); i++) { SoFullPath * p = (SoFullPath*) pl[i]; if (p->getTail()->isOfType(type)) { SoGroup * g = (SoGroup*) p->getNodeFromTail(1); g->removeChild(p->getIndexFromTail(0)); } } sa.reset(); } int main(int argc, char ** argv ) { if (argc < 3) { fprintf(stderr,"Usage: reorganize [nostrip]\n"); return -1; } SbBool strip = TRUE; if (argc > 3) { if (strcmp(argv[3], "nostrip") == 0) strip = FALSE; else { fprintf(stderr,"Usage: reorganize [nostrip]\n"); return -1; } } SoDB::init(); SoInteraction::init(); SoInput input; SbBool ok = input.openFile(argv[1]); if (!ok) { fprintf(stderr,"Unable to open file.\n"); return -1; } SoSeparator * root = SoDB::readAll(&input); SbBool vrml1 = input.isFileVRML1(); SbBool vrml2 = input.isFileVRML2(); if (vrml2) { fprintf(stderr,"VRML2 not supported yet\n"); return -1; } if (!root) { fprintf(stderr,"Unable to read file.\n"); return -1; } root->ref(); fprintf(stderr,"Applying SoReorganizeAction..."); SoReorganizeAction reorg; reorg.apply(root); fprintf(stderr,"done\n"); SoOutput out; if (out.openFile(argv[2])) { if (strip) { // strip coord3, texcoord and normal nodes fprintf(stderr,"stripping old nodes from scene graph\n"); strip_node(SoCoordinate3::getClassTypeId(), root); strip_node(SoCoordinate4::getClassTypeId(), root); strip_node(SoNormal::getClassTypeId(), root); strip_node(SoTextureCoordinate2::getClassTypeId(), root); } fprintf(stderr,"writing target\n"); SoWriteAction wa(&out); wa.apply(root); } root->unref(); return 0; } // main() ``` **Since** Coin 2.5 ## Constructor & Destructor Documentation ### SoReorganizeAction::SoReorganizeAction (SoSimplifier \* simplifier = NULL) A constructor. ### SoReorganizeAction::~SoReorganizeAction (void ) \[virtual\] The destructor. ## Member Function Documentation ### SoType SoReorganizeAction::getTypeId (void ) const \[virtual\] Returns the type identification of an object derived from a class inheriting **SoAction**. This is used for runtime type checking and "downward" casting. Reimplemented from **SoSimplifyAction**. ### SoType SoReorganizeAction::getClassTypeId (void ) \[static\] This static method returns the **SoType** object associated with objects of this class. ### void SoReorganizeAction::addMethod (const SoType type, SoActionMethod method) \[static\] *This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.*\ ### void SoReorganizeAction::enableElement (const SoType type, const int stackindex) \[static\] *This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.*\ ### const SoEnabledElementsList & SoReorganizeAction::getEnabledElements (void ) const \[protected\], \[virtual\] Returns list of enabled elements. Reimplemented from **SoSimplifyAction**. ### SoEnabledElementsList \* SoReorganizeAction::getClassEnabledElements (void ) \[static\], \[protected\] Returns list of enabled elements for this class. The enabledElements and methods variables are protected in the original OIV API. This is not such a good idea, since exposed static class member variables is a major grievance with regard to Win32 DLLs. This function is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.\ ### SoActionMethodList \* SoReorganizeAction::getClassActionMethods (void ) \[static\], \[protected\] Returns list of action methods for this class. The enabledElements and methods variables are protected in the original OIV API. This is not such a good idea, since exposed static class member variables is a major grievance with regard to Win32 DLLs. This function is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.\ ### void SoReorganizeAction::initClass (void ) \[static\] Initializes the runtime type system for this class, and sets up the enabled elements and action method list. ### void SoReorganizeAction::apply (SoNode \* root) \[virtual\] Applies the action to the scene graph rooted at *root*. Note that you should *not* apply an action to a node with a zero reference count. The behavior in that case is undefined. Reimplemented from **SoSimplifyAction**. ### void SoReorganizeAction::apply (SoPath \* path) \[virtual\] Applies the action to the parts of the graph defined by *path*. Note that an **SoPath** will also contain all nodes that may influence e.g. geometry nodes in the path. So for instance applying an **SoGLRenderAction** on an **SoPath** will render that path as expected in the view, where geometry will get its materials, textures, and other appearance settings correctly. If the *path* ends in an **SoGroup** node, the action will also traverse the tail node's children. Reimplemented from **SoSimplifyAction**. ### void SoReorganizeAction::apply (const SoPathList & pathlist, SbBool obeysrules = FALSE) \[virtual\] Applies action to the graphs defined by *pathlist*. If *obeysrules* is set to TRUE, *pathlist* must obey the following four conditions (which is the case for path lists returned from search actions for non-group nodes and path lists returned from picking actions): All paths must start at the same head node. All paths must be sorted in traversal order. The paths must be unique. No path can continue through the end point of another path. **See also** **SoAction::apply(SoPath \* path)** Reimplemented from **SoSimplifyAction**. ### void SoReorganizeAction::beginTraversal (SoNode \* node) \[protected\], \[virtual\] This virtual method is called from **SoAction::apply()**, and is the entry point for the actual scene graph 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 scene graph traversal.
