2006 - Article - Exploratory visualization based on multidimensional transfer functions and star coordinates




Abstract: Exploration and analysis of multivariate data play an important role in different domains. This work proposes a simple interface prototype that allows a human beimg to explore visually multivariate spatial objects, like image, sequence of images or volume. It uses star coordinates to display the multivariate data on the computer 2D screen. Once a user identifies a feature on this powerful coordinate system, he/she maps a selected feature region on such widget to a color and an opacity. As a visual result, the feature is rendered on the object space domain by the use of these maps. We also show some examples that illustrates the interface potencial to some applications.
