Non-linear Perspective Widgets for Creating Multiple-View Images

This is the paper version of the tech report. The full details can be found in Nisha\s thesis. Viewing data sampled on complicated geometry, such as a helix or atorus, is hard because a single camera view can only encompass a partof the object. Either multiple views or non-linear projection can beused to expose more of the object in a single view, however, specifying such views is challenging because of the large number ofparameters involved. We show that a small set of versatile widgetscan be used to quickly and simply specify a wide variety of suchviews. These widgets are built on top of a general framework that inturn encapsulates a variety of complicated camera placement issuesinto a more natural set of parameters, making the specification of newwidgets, or combining multiple widgets, simpler. This framework isentirely view-based and leaves intact the underlying geometry of thedataset, making it applicable to a wide range of data types.
