TwoWayViewportSync Class

Forms a bidirectional connection between two Viewports such that the ViewStates of each are synchronized with one another. For example, panning in one viewport will cause the other viewport to pan by the same distance, and changing the RenderMode of one viewport will change it in the other viewport. By default, all aspects of the views - display style, category and model selectors, frustum, etc - are synchronized, but this can be customized by subclassing and overriding the TwoWayViewportSync.syncViewports and connectViewports methods.

see Multiple Viewport Sample for an interactive demonstration.

see TwoWayViewportFrustumSync to synchronize only the frusta of the viewports.

see connectViewportViews to synchronize the state of more than two viewports.
