Hi Hind lwahhabi,
This is the code to store all parts of the VRML-object into a hashtable.
After that, you can retrieve all elements by calling get(" <the
objectname> ");
Call VrmlScene.getNamedObjects() to get a Hashtable with of the DEF'd nodes
in
the VRML file.
For example, if your VRML file has:
DEF OBJ Transform { ...}
Then you can retieve "OBJ" by calling:
VrmlLoader loader = new VrmlLoader();
VrmlScene scene = loader.load(someUrl);
Hashtable defTable = scene.getNamedObject();
TransformGroup obj = (TransformGroup) defTable.get("OBJ");
Note: The entries in the Hashtable will be stored by the DEF name and will
be
Java3D nodes. The specific node type will depend on the Java3D
implementation
of the VRML node. Most are pretty direct, i.e. Transform->TransformGroup,
although sometimes a single VRML node will be implemented as a subgraph of
Java3D nodes.
Succes,
