Vector plots for irregular grids
D. Dovey · IEEE Visualization · 1995
A standard method for visualizing vector fields consists of drawing many small ``glyphs'' to represent the field. This paper extends the technique from regular to curvilinear and unstructured grids. In order to achieve a uniform density of vector glyphs on nonuniformly spaced grids, the paper describes two approaches to resampling the grid data. One of the methods, an element-based resampling, can be used to visualize vector fields at arbitrary surfaces within three-dimensional grids.
