Decal-Maps: Real-Time Layering of Decals on Surfaces for Multivariate Visualization. IEEE Transactions on Visualization and Computer Graphics, 23(1), 821–830. https://doi.org/10.1109/tvcg.2016.25988661941-0506http://hdl.handle.net/1880/11055910.11575/PRISM/46123We introduce the use of decals for multivariate visualization design. Decals are visual representations that are used for communication; for example, a pattern, a text, a glyph, or a symbol, transferred from a 2D-image to a surface upon contact. By creating what we define as decal-maps, we can design a set of images or patterns that represent one or more data attributes. We place decals on the surface considering the data pertaining to the locations we choose. We propose a (texture mapping) local parametrization that allows placing decals on arbitrary surfaces interactively, even when dealing with a high number of decals. Moreover, we extend the concept of layering to allow the co-visualization of an increased number of attributes on arbitrary surfaces. By combining decal-maps,color-maps and a layered visualization, we aim to facilitate and encourage the creative process of designing multivariate visualizations. Finally, we demonstrate the general applicability of our technique by providing examples of its use in a variety of contexts.enUnless otherwise indicated, this material is protected by copyright and has been made available with authorization from the copyright owner.
