Visualizing Motion Data in Virtual Reality: Understanding the Roles of Animation, Interaction, and Static Presentation
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
We present a study of interactive virtual reality visualizations of scientific motions as found in biomechanics experiments. Our approach is threefold. First, we define a taxonomy of motion visualizations organized by the ...
StratomeX: Visual Analysis of Large-Scale Heterogeneous Genomics Data for Cancer Subtype Characterization
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
Identification and characterization of cancer subtypes are important areas of research that are based on the integrated analysis of multiple heterogeneous genomics datasets. Since there are no tools supporting this process, ...
Polynomial Optics: A Construction Kit for Efficient Ray-Tracing of Lens Systems
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
Simulation of light transport through lens systems plays an important role in graphics. While basic imaging properties can be conveniently derived from linear models (like ABCD matrices), these approximations fail to ...
Perception of Animated Node-Link Diagrams for Dynamic Graphs
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
Effective visualization of dynamic graphs remains an open research topic, and many state-of-the-art tools use animated node-link diagrams for this purpose. Despite its intuitiveness, the effectiveness of animation in ...
Globally Consistent Space-Time Reconstruction
(2010)
Most objects deform gradually over time, without abrupt changes in geometry or topology, such as changes in genus. Correct space-time reconstruction of such objects should satisfy this gradual change prior. This requirement ...
A Salience-based Quality Metric for Visualization
(The Eurographics Association and Blackwell Publishing Ltd., 2010)
Salience detection is a principle mechanism to facilitate visual attention. A good visualization guides the observer s attention to the relevant aspects of the representation. Hence, the distribution of salience over a ...
Understanding Interactive Legends: a Comparative Evaluation with Standard Widgets
(The Eurographics Association and Blackwell Publishing Ltd., 2010)
Interactive information visualization systems rely on widgets to allow users to interact with the data and modify the representation. We define interactive legends as a class of controls combining the visual representation ...
The Readability of Path-Preserving Clusterings of Graphs
(The Eurographics Association and Blackwell Publishing Ltd., 2010)
Graph visualization systems often exploit opaque metanodes to reduce visual clutter and improve the readability of large graphs. This filtering can be done in a path-preserving way based on attribute values associated with ...
Fast Generation of Pointerless Octree Duals
(2010)
Geometry processing applications frequently rely on octree structures, since they provide simple and efficient hierarchies for discrete data. However, octrees do not guarantee direct continuous interpolation of this data ...
Fuzzy Geodesics and Consistent Sparse Correspondences For Deformable Shapes
(2010)
A geodesic is a parameterized curve on a Riemannian manifold governed by a second order partial differential equation. Geodesics are notoriously unstable: small perturbations of the underlying manifold may lead to dramatic ...
