This example shows how to create two World Windows, each in its own JFrame. The World Windows share a globe and some
layers.
Applications using multiple World Wind windows simultaneously should instruct World Wind to share OpenGL and other
resources among those windows. Most World Wind classes are designed to be shared across
WorldWindow objects
and are shared automatically. But OpenGL resources are not automatically shared. To share them, a reference to a
previously created WorldWindow must be specified as a constructor argument for subsequently created WorldWindows.
Most World Wind
Globe and
Layer objects can be
shared among World Windows. Those that cannot be shared have an operational dependency on the World Window they're
associated with. An example is the
ViewControlsLayer layer for on-screen
navigation. Because this layer responds to input events within a specific World Window, it is not sharable. Refer to
the World Wind Overview page for a list of layers that cannot be shared.
// TODO: include the reference to overview.html.
