The latest release of VisAD on our ftp server now includes
a class visad/bom/PickManipulationRendererJ3D.java that will
make this task much easier. See the main() method of this
class for an example of how to use it. Given a Data object
such as 'shape' you can tell when its been 'picked' in a
display as follows:
DataReferenceImpl sref = new DataReferenceImpl("shape");
sref.setData(shape);
display.addReferences(new PickManipulationRendererJ3D(), sref);
CellImpl cells = new CellImpl() {
private boolean first = true;
public void doAction() throws VisADException, RemoteException {
if (first) first = false;
else System.out.println("shape picked");
}
};
cells.addReference(sref);
Clicking the right mouse button on the depiction of 'shape'
does not change its value, but does send an event to the
CellImpl.
Cheers,
Bill
