set capabilities on a loaded universe
I'm loading an Universe using the SceneGraphStreamReader from a file.
The code looks like this :
URL url=new URL(getCodeBase().toString()+j3d_File);
InputStream input_stream = url.openStream();
SceneGraphStreamReader reader = new SceneGraphStreamReader(input_stream);
It works fine. The problem is that I want to change the capabilities of some BranchGroups before they are made live. I want to add new components to those groups.
Is there a way to load the universe, change capabilities, add new things and then set it to the canvas3D? So I can see it modified
