1 Freire, Juliana; Silva, Claudio T.VisMashup: streamlining the creation of custom visualization applicationsVisualization is essential for understanding the increasing volumes of digital data. However, the process required to create insightful visualizations is involved and time consuming. Although several visualization tools are available, including tools with sophisticated visual interfaces, they are o...VisMashup; Dataflow; Visualization systems; Mashups; Medleys2009-11
2 Hansen, Charles D.Illustrative interactive stipple renderingAbstract-Simulating hand-drawn illustration can succinctly express information in a manner that is communicative and informative. We present a framework for an interactive direct stipple rendering of volume and surface-based objects. By combining the principles of artistic and scientific illustratio...2003-04
3 Hansen, Charles D.; Whitaker, Ross T.Streaming narrow-band algorithm: interactive computation and visualization of level setsAbstract-Deformable isosurfaces, implemented with level-set methods, have demonstrated a great potential in visualization and computer graphics for applications such as segmentation, surface processing, and physically-based modeling. Their usefulness has been limited, however, by their high computa...2004-07
4 Hansen, Charles D.Multidimensional transfer functions for interactive volume renderingAbstract-Most direct volume renderings produced today employ one-dimensional transfer functions which assign color and opacity to the volume based solely on the single scalar quantity which comprises the data set. Though they have not received widespread attention, multidimensional transfer function...2002-07
5 Hansen, Charles D.Model for volume lighting and modelingAbstract-Direct volume rendering is a commonly used technique in visualization applications. Many of these applications require sophisticated shading models to capture subtle lighting effects and characteristics of volumetric data and materials. For many volumes, homogeneous regions pose problems f...2003-04
6 Hansen, Charles D.Flow charts: visualization of vector fields on arbitrary surfacesWe introduce a novel flow visualization method called Flow Charts, which uses a texture atlas approach for the visualization of flows defined over curved surfaces. In this scheme, the surface and its associated flow are segmented into overlapping patches, which are then parameterized and packed in ...2008-09
7 Hansen, Charles D.Reconstruction and visualization of planetary nebulaeAbstract-From our terrestrially confined viewpoint, the actual three-dimensional shape of distant astronomical objects is, in general, very challenging to determine. For one class of astronomical objects, however, spatial structure can be recovered from conventional 2D images alone. So-called planet...2005-09
