Eurographics 2012 Workshop on 3D Object Retrieval
Never before has Virtual and Augmented Reality hardware been so affordable allowing so many new applications of these technologies; however, developing these applications implies specific skills that are not usually acquired in core courses in Computer Science/Engineering. In this context, specific courses introducing the basics on these technologies seem to be most relevant. With this panel we intend to foster a discussion concerning what should an introductory course on Virtual/Augmented Reality be as of 2017....
There is a growing demand from the media industry, including computer games, virtual reality and simulation, for increasing realism in real-time for their computer generated images. Despite considerable advances in processing power and graphics hardware, increasing scene complexity means that it is still not possible to achieve high fidelity computer graphics in a reasonable, let alone real, time on a single computer. Cost prediction is a technique which acquires knowledge of computational complexity within the...

The detection and analysis of mesoscale ocean eddies is a complex task, made more difficult when simulated or observational ocean data are massive. We present the statistical approach of change point detection as a means to help scientists efficiently extract relevant scientific information. We demonstrate the value of change point detection for the characterization of eddy behavior in simulated ocean data. Our results show that change point detection helps with the identification of significant parameter...
Reality TV shows that follow people in their day-to-day lives are not a new concept. However, the traditional methods used in the industry require a lot of manual labor and need the presence of at least one physical camera man. Because of this, the subjects tend to behave differently when they are aware of being recorded. This paper presents an approach to follow people in their day-to-day lives, for long periods of time (months to...

This paper explores two general methods for incorporating volumetric uncertainty information in direct volume rendering. The goal is to produce volume rendered images that depict regions of high (or low) uncertainty in the data. The first method involves incorporating the uncertainty information directly into the volume rendering equation. The second method involves post-processing information of volume rendered images to composite uncertainty information. We present some initial findings on what mappings provide qualitatively satisfactory results and...
Position Based Dynamics (PBD) methodology is a widely used approach for simulation of deformable bodies in the context of video games. Its main advantages over force based methods are its unconditional stability and its constraint based approach. However, it does not involve physically inspired parameters and its behaviour depends on time step size. This makes it difficult to reproduce a given elastic behaviour. In this work we perform an analysis of the mechanical properties in...
Hierarchical Clustering with Multiple-Height Branch-Cut Applied to Short Time-Series Gene Expression DataAthanasios Vogogias, Jessie Kennedy & Daniel Archambault
Rigid adherence to pre-specified thresholds and static graphical representations can lead to incorrect decisions on merging of clusters. As an alternative to existing automated or semi-automated methods, we developed a visual analytics approach for performing hierarchical clustering analysis of short time-series gene expression data. Dynamic sliders control parameters such as the similarity threshold at which clusters are merged and the level of relative intra-cluster distinctiveness, which can be used to identify "weak-edges" within clusters. An...

This paper presents powerful surface based techniques for the analysis of complex flow fields resulting from CFD simulations. Emphasis is put on the examination of vortical structures. An improved method for stream surface computation that delivers accurate results in regions of intricate flow is presented, along with a novel method to determine boundary surfaces of vortex cores. A number of surface techniques are presented that aid in understanding the flow behavior displayed by these surfaces....
ViSTA FlowLib - A Framework for Interactive Visualization and Exploration of Unsteady Flows in Virtual EnvironmentsM. Schirski, A. Gerndt, T. Van Reimersdahl, T. Kuhlen, P. Adomeit, O. Lang, S. Pischinger & C. Bischof
In the past a lot of work has been invested in various aspects of an interactive visualization of CFD simulation data. This includes e.g. increasing the rendering speed and responsiveness of complex visualizations, using and enhancing multimodal user interfaces, and incorporating parallel approaches for an efficient extraction of flow properties and their respective visual representation. Still, only few projects combine the significant advances in these areas. In this paper, we describe our software framework ViSTA...
