The Contour Spectrum is a tool presented at last year's Viz which
helps the user find good isovalues for effective isosurface
renderings. Important metrics of an isosurface, such as mean gradient
magnitude and surface area, are computed very efficiently, and then
the results of evaluating those metrics over the range of isovalues is
presented to the user in a compact visual form. This can then help
the user pick a good isovalue. The application here isn't direct
volume rendering, but the relevence to our paper is that the contour
spectrum is a good example of how an interface can use measured
property of the data to guide the user through the parameter space
controlling the rendering.
