Surface Reconstruction of Noisy and Defective Data Sets
Found in: Visualization Conference, IEEE
By Hui Xie, Kevin T. McDonnell, Hong Qin
Issue Date:October 2004
pp. 259-266
We present a novel surface reconstruction algorithm that can recover high-quality surfaces from noisy and defective data sets without any normal or orientation information. A set of new techniques are introduced to afford extra noise tolerability, robust o...
A network-based interface for the exploration of high-dimensional data spaces
Found in: Visualization Symposium, IEEE Pacific
By Zhiyuan Zhang,Kevin T. McDonnell,Klaus Mueller
Issue Date:March 2012
pp. 17-24
The navigation of high-dimensional data spaces remains challenging, making multivariate data exploration difficult. To be effective and appealing for mainstream application, navigation should use paradigms and metaphors that users are already familiar with...
Color Design for Illustrative Visualization
Found in: IEEE Transactions on Visualization and Computer Graphics
By Lujin Wang, Joachim Giesen, Kevin T. McDonnell, Peter Zolliker, Klaus Mueller
Issue Date:November 2008
pp. 1739-1754
Professional designers and artists are quite cognizant of the rules that guide the design of effective color palettes, from both aesthetic and attention-guiding points of view. In the field of visualization, however, the use of systematic rules embracing t...
Dynamic Sculpting and Animation of Free-Form Subdivision Solids
Found in: Computer Animation
By Kevin T. McDonnell, Hong Qin
Issue Date:May 2000
pp. 126
This paper presents a sculptured solid modeling system founded upon dynamic Catmull-Clark subdivision-based solids of arbitrary topology. Our primary contribution is that we integrate the geometry of sculptured free-form solids with the powerful physics-ba...
Visual Correlation Analysis of Numerical and Categorical Data on the Correlation Map
Found in: IEEE Transactions on Visualization and Computer Graphics
By Zhiyuan Zhang,Kevin T. McDonnell,Erez Zadok,Klaus Mueller
Issue Date:February 2015
pp. 1
Correlation analysis can reveal the complex relationships that often exist among the variables in multivariate data. However, as the number of variables grows, it can be difficult to gain a good understanding of the correlation landscape and important intr...
A Structure-Based Distance Metric for High-Dimensional Space Exploration with Multidimensional Scaling
Found in: IEEE Transactions on Visualization and Computer Graphics
By Jenny Hyunjung Lee,Kevin T. McDonnell,Alla Zelenyuk,Dan Imre,Klaus Mueller
Issue Date:March 2014
pp. 351-364
Although the euclidean distance does well in measuring data distances within high-dimensional clusters, it does poorly when it comes to gauging intercluster distances. This significantly impacts the quality of global, low-dimensional space embedding proced...
CEASAR: Accurate and Robust Algorithm for Extracting a Smooth Centerline
Found in: Visualization Conference, IEEE
By Ingmar Bitter, Mie Sato, Michael Bender, Kevin T. McDonnell, Arie Kaufman, Ming Wan
Issue Date:October 2000
pp. 4
We present CEASAR, a centerline extraction algorithm that delivers smooth, accurate, and robust results. Centerlines are needed for accurate measurements of length along winding tubular structures. Centerlines are also required in automatic virtual navigat...
A new solid subdivision scheme based on box splines
Found in: Proceedings of the seventh ACM symposium on Solid modeling and applications (SMA '02)
By Hong Qin, Kevin T. McDonnell, Yu-Sung Chang
Issue Date:June 2002
pp. 226-233
During the past twenty years, much research has been undertaken to study surface representations based on B-splines and box splines. In contrast, volumetric splines have received much less attention as an effective and powerful solid modeling tool. In this...
FEM-based subdivision solids for dynamic and haptic interaction
Found in: Proceedings of the sixth ACM symposium on Solid modeling and applications (SMA '01)
By Hong Qin, Kevin T. McDonnell
Issue Date:May 2001
pp. 312-313
Molds are required in a large number of manufacturing operations such as metal casting, die making, injection molding, ceramic and polymer processing etc. Molded and cast parts are used extensively because they produce net-shape parts that require minimal ...
Virtual clay: a real-time sculpting system with haptic toolkits
Found in: Proceedings of the 2001 symposium on Interactive 3D graphics (SI3D '01)
By Hong Qin, Kevin T. McDonnell, Robert A. Wlodarczyk
Issue Date:March 2001
pp. 179-190
we present an exact and interactive collision detection system, I-COLLIDE, for large-scale environments. Such environments are characterized by the number of objects undergoing rigid motion and the complexity of the models. The algorithm does not assume th...
