pacific

A region of the Pacific Ocean with many swirling ROIs.

            pacific.ds:     density, velocity, and energy values on an
                            implicit rectangular grid (density and energy are
                            dummy values)

      pacific.swirl.ds:     scalar swirl-parameter values on an implicit
                            rectangular grid

pacific.curvilinear.ds:     density, velocity, and energy values on an
                            artificially generated curvilinear grid (i.e.,
                            the dataset has been "warped")

            pacific.sm:     the corresponding segmentation map wherein three
                            swirls have been identified as ROIs 1, 2, and 3.
                            The background (the rest of the swirls) is ROI 0.
