Koiter's Thin Shells on Catmull-Clark Limit Surfaces
(The Eurographics Association, 2011)
We present a discretization of Koiter's model of elastic thin shells based on a finite element that employs limit surfaces of Catmull Clark's subdivision scheme. The discretization can directly be applied to control grids ...
A Framework for the Multi-Temporal Analysis of Land Cover Change using Visual Analytics
(The Eurographics Association, 2011)
Land cover change analysis serves as a basis for planning processes in a wide range of applications. For this task, the use of remote sensing data has become more popular over the last decades. However, despite much research ...
Generating Large-scale Details: Altering Soil Surface and Structure with Tracks
(The Eurographics Association, 2011)
Tracks, footsteps and ruts are common elements we can observe in natural sceneries. Wherever there is human activity, we can find marks on the ground left by vehicles or walkers. These marks can be directly dug from a soft ...
Improving High-Speed Scanning Systems by Photometric Stereo
(The Eurographics Association, 2011)
High-speed scanning systems can be extremely valuable for Cultural Heritage applications, especially when large collections of small objects have to be acquired. However, fine details may not be acquired using this technology. ...
Contingency Wheel: Visual Analysis of Large Contingency Tables
(The Eurographics Association, 2011)
We present the Contingency Wheel, a visual method for finding and analyzing associations in a large nxm contingency table with m less than 100 and n being two to three orders of magnitude larger than m. The method is ...
Methods for Measuring State Error for Control of Animated Human Figures
(The Eurographics Association, 2011)
Proportional plus Derivative (PD) control has been used widely to calculate the required forces to drive physically-based character animation. This approach requires the measurement of the state error or the difference ...
Characterizing Visual Analytics in Diagnostic Imaging
(The Eurographics Association, 2011)
Many necessary and desired improvements in healthcare are dependent on progress in medical imaging. As shown in this paper, the challenges targeted by visual analytics (VA) coincide with main challenges for radiologists' ...
Serious Games for Cultural Heritage: the GaLA Activities
(The Eurographics Association, 2011)
The European Union is increasingly investing in new techniques for the acquisition, preservation and fruition of Virtual Heritage. In addition, Serious Games (games designed with an educational purpose) are an emerging way ...
XML3D Physics: Declarative Physics Simulation for the Web
(The Eurographics Association, 2011)
As interactive 3D graphics has become an integral part of modern Web browsers via the low-level WebGL API [Khr11], it now becomes apparent that higher-level declarative approaches integrated with HTML5 are needed in order ...
Two Simple Single-pass GPU methods for Multi-channel Surface Voxelization of Dynamic Scenes
(The Eurographics Association, 2011)
An increasing number of rendering and geometry processing algorithms relies on volume data to calculate anything from effects like smoke/fluid simulations, visibility information or global illumination effects. We present ...
