Hi Karthikeyan,
In this call,
mainBranchGroup.addChild(createSceneGraph(canvas3D));
The canvas3D may still reference to old View or
you may have some other global variable refer to
SimpleUniverse.
You should also set ViewingPlatform to null and remove
all Canvas3D attach to the View as follows:
simpleuniverse.getViewer().setViewingPlatform(null);
simpleuniverse.getViewer().getView().removeCanvas3D(c3d);
Note that
simpleuniverse.getViewer().setViewingPlatform(null);
is used instead of
simpleuniverse.getViewer().getView().attachViewPlatform(null)
If SimpleUniverse utility is used.
It is because the ViewingPlatform utility will still hold a reference
to Viewer which in turn hold reference to View.
In fact, a better way is too invoke
VirtualUniverse.removeAllLocales()
and recreate the VirtualUniverse again in refresh().
Also, please use v1.2.1 beta1 as there are bugs in v1.2
which leak memory.
Thanks.
