public class TranslucentMultiViewImpl

extends DefaultMultiViewImpl

A sample implementation of a MultiView. This MultiView renders all views with positive display values, making views with values less than 1 partially transparent.

This view is designed to be used with Semantic Zooming, which is a technique that allows you to change the View of an object at different zoom levels. For example, when seen afar, a web page may be rendered as just a square, while close-up it may show more details.
