Ah, this is a question more about application architecture more than
what Xj3D can do. If your application wants to directly access parts of
the scene graph, you may be better off using the EAI (vrml.eai)
interfaces that are part of the VRML97 specification. This would give
you the direct ability to send events to the input of a particular node
in the scene without needing to get dirty in the guts of Xj3D.
The better way of doing this, is to use the VRMLScene object and query
it for particular nodes. If you already have the PointSet node marked
with a DEF, then use the getDEFNodes() map and looking up the
appropriate node that you are interested in. Then, you find out the
index of the field that you want to write to using getFieldIndex(). Once
you have the index, you can directly write the value to the node using
the appropriate setValue() call. Here's a bit of psuedo code to try to
explain this better:
VRMLScene scene = loader.loadNow(inputsource);
Map defs = scene.getDEFNodes();
VRMLNodeType my_pointset = defs.get("NODE_OF_INTEREST");
int field_index = my_script.getFieldIndex("point");
my_pointset.setValue(field_index, new float[] {.....});
