Re: [JAVA3D] Mixing Java3D Nodes and VRML worlds

[Jack Gundrum]

I load a VRML file and then access the geometry without using the node DEFS
with the following

VrmlLoader              loader = new VrmlLoader();
                 Scene s = null;

                 try {
                         s = loader.load(reader);
                 }
                 catch (FileNotFoundException e) {
                         System.err.println(e);
                         System.exit(1);
                 }
                 catch (ParsingErrorException e) {
                         System.err.println(e);
                         System.exit(1);
                 }
                 catch (IncorrectFormatException e) {
                         System.err.println(e);
                         System.exit(1);
                 }

                 BranchGroup bg = new BranchGroup();
                 bg.setCapability(BranchGroup.ALLOW_CHILDREN_READ);
                 bg = s.getSceneGroup();
                 Enumeration enum1 = bg.getAllChildren();
                 iterateLoop(enum1);


public void iterateLoop(Enumeration enum){
                 while (enum.hasMoreElements())
                 {
                         Object tmpObject = enum.nextElement();

                         if (tmpObject instanceof Shape3D)
                         {
                                 createShape(tmpObject);
                         }

                         else if (tmpObject instanceof TransformGroup)
                         {
                                 //System.out.println("What a transformgroup");
                                 TransformGroup tmptransformGroup =
(TransformGroup) tmpObject;

                                 Enumeration nextenum =
tmptransformGroup.getAllChildren();

                                 iterateLoop(nextenum);
                         }

                         else if(tmpObject instanceof Group){
                                 //System.out.println("What a group");
                                 Group tmpGroup = (Group)
tmpObject;
                                 Enumeration groupenum =
tmpGroup.getAllChildren();

                                 iterateLoop(groupenum);
                         }

                         else{System.out.println("What is this thing?");
                         }
                 }
         }
