Doesn't the VirtualUniverse.removeAllLocales() remove the view side of the
SU as well? Then I've got to go about rebuilding it line by line? Is there
a way just to remove all the content side of the scene graph with just one
line? right now I'm using the following:
Enumeration allBGs = dummyU.getLocale().getAllBranchGraphs();
// first branchgroup is the view branch, leave it alone...
BranchGroup BG = (BranchGroup)allBGs.nextElement();
// if another branchgroup exists, it is the content group, so remove
it.
if (allBGs.hasMoreElements()) {
BG = (BranchGroup)allBGs.nextElement();
dummyU.getLocale().removeBranchGraph(BG);
BG=null;
}
