Non-linear Perspective Widgets for Exploration of Complex Data-sets

Viewing data sampled on complicated geometry such as a human pelvis or helix is hard. A single camera view is not sufficient to view different parts of such a complicated dataset. Multiple views are needed in order to completely examine the structure. In this paper, we present a general tool-kit consisting of a set of versatile widgets, namely the unwrap, the clipping, the fisheye, and the panorama widgets, each of which encapsulates a variety of complicated camera placement issues and then combines these several camera views into a single view in real-time. These non-linear views give a more complete visualization of the structure without modifying the underlying geometry of the dataset. Multiple widgets can be combined to facilitate better understanding of the underlying structure.
