Structuring Feature Space: A Non-Parametric Method for Volumetric Transfer Function Generation
Found in: IEEE Transactions on Visualization and Computer Graphics
By Ross Maciejewski, Insoo Woo, Wei Chen, David Ebert
Issue Date:November 2009
pp. 1473-1480
The use of multi-dimensional transfer functions for direct volume rendering has been shown to be an effective means of extracting materials and their boundaries for both scalar and multivariate data. The most common multi-dimensional transfer function cons...
 
Abstracting Attribute Space for Transfer Function Exploration and Design
Found in: IEEE Transactions on Visualization and Computer Graphics
By R. Maciejewski, Yun Jang, Insoo Woo,H. Ja╠łnicke,K. P. Gaither,D. S. Ebert
Issue Date:January 2013
pp. 94-107
Currently, user centered transfer function design begins with the user interacting with a one or two-dimensional histogram of the volumetric attribute space. The attribute space is visualized as a function of the number of voxels, allowing the user to expl...
 
Feature-Driven Data Exploration for Volumetric Rendering
Found in: IEEE Transactions on Visualization and Computer Graphics
By Insoo Woo,Ross Maciejewski,Kelly P. Gaither,David S. Ebert
Issue Date:October 2012
pp. 1731-1743
We have developed an intuitive method to semiautomatically explore volumetric data in a focus-region-guided or value-driven way using a user-defined ray through the 3D volume and contour lines in the region of interest. After selecting a point of interest ...
 
Evaluating the effectiveness of visualization techniques for schematic diagrams in maintenance tasks
Found in: Proceedings of the 7th Symposium on Applied Perception in Graphics and Visualization (APGV '10)
By David S. Ebert, Insoo Woo, Krystal Thomas, Ross Maciejewski, Sungye Kim, Timothy D. Ropp
Issue Date:July 2010
pp. 33-40
In order to perform daily maintenance and repair tasks in complex electrical and mechanical systems, technicians commonly utilize a large number of diagrams and documents detailing system properties in both electronic and print formats. In electronic docum...
