Abstract
We present a method that flattens a curved surface and its neighborhood to create
effective, uncluttered visualizations by applying standard flow visualization techniques
in the deformed space. Level sets of the distance from the curved surface are mapped
to parallel planes. Data fields are mapped accordingly. Our method eases the visual
inspection and analysis of a curved surface's vicinity by providing a flat space that
supports the creation of standardized views. This is particularly useful for visualizing
flow fields in the boundary layer.
