Vicky,
One thing you can do is extract named groups from an .obj with ease, that may
be enough. Essentially it lets you enclose several (usually related) objects
in the .obj.
here's some simplified code (no try/catch)
ObjectFile f = new ObjectFile(flags, (float)(0 * Math.PI / 180.0));
Scene s = null;
s = f.load(tankObject);
java.util.Hashtable views = s.getNamedObjects();
Shape3D shape1;
Shape3D shape2;
for (Enumeration e = views.keys() ; e.hasMoreElements() ;) {
String current = (String) e.nextElement();
if (current.equals("name1")) {
shape1 = (Shape3D) views.get(current);
} else if (current.equals("name2")) {
shape2 = (Shape3D) views.get(current);
}
}
Cheers,
Will.
