Interface Display

All Known Subinterfaces:

LocalDisplay, RemoteDisplay

public abstract interface Display

extends Action

Display is the VisAD interface for displays. It is runnable.

The display architecture is based on three goals:

1. Display data according to a set of mappings from RealType's (e.g., Latitude, Time, Pressure) to DisplayRealTypes (e.g., XAxis, RGB, Animation).

2. Allow user extensions, to define new DisplayRealTypes, new DisplayTupleTypes (and hence new display CoordinateSystems), and new rendering algorithms.

3. Support direct manipulation, where users modify Data values by re-drawing their depictions.
