Javadoc
Schedules the rendering of a frame into this Canvas3D's
off-screen buffer. The rendering is done from the point of
view of the View object to which this Canvas3D has been added.
No rendering is performed if this Canvas3D object has not been
added to an active View. This method does not wait for the rendering
to actually happen. An application that wishes to know when
the rendering is complete must either subclass Canvas3D and
override the postSwap
method, or call
waitForOffScreenRendering
.
