Focus+Context via Snaking Paths
Focus+context visualizations reveal specific structures in high detail while effectively depicting its surroundings, often relying on transitions between the two areas to provide context. We present an approach to generate focus+context visualizations depicting cylindrical structures along snaking …

Balanced Multiresolution in Multilevel Focus+Context Visualization
… scheme in constructing an interactive multilevel focus+context visualization framework for the navigation and exploration of large-scale 2D and 3D images. Typically, the given filters are floating-point values, so our BWTs reversibly map integers to floating-point i.e. real values. We extend our …

PolarEyez: A Radial Focus+Context Visualization for Multidimensional Functions
… of the visualization in accordance with the focus+context technique. The functional values are mapped onto a color scheme with shades of green representing positive function values, and shades of red representing negative function values. Interactive features such as the ability to change the …

Interactive rendering techniques for focus+context visualization of 3D geovirtual environments
… rendering techniques and applications for focus+context visualization of interactive 3D geovirtual environments such as virtual 3D city and landscape models. These environments are generally characterized by a large number of objects and are of high complexity with respect to geometry and …

Analysis and exploration of virtual 3D city models using 3D information lenses
… for 3D information lenses based on the focus & context metaphor. It analyzes, conceives, implements, and reviews its applicability to objects and structures of virtual 3D city models. In contrast to digital terrain models, the application of focus & context visualization to virtual 3D …

Applying Information Visualization Techniques to Visual Debugging
… visualization techniques such as zooming, focus and context, or graphical representation of numeric data may enhance the visual debugging experience. To this end, drawing data structures as graphs is potentially a step in the right direction, but more must be done to maximize the value of …

Focus-based Interactive Visualization for Structured Data
… based on their changing interests, several focus-based interactive visualization methods have been described. To allow users to discover specific contextual information around the focus in large semantic graphs, we propose to use the embedded semantic queries during browsing as the main …

Improving memorability in fisheye views
… distortion to show both local detail and global context in the same display space. Although fisheyes allow the presentation and inspection of large data sets, the distortion effects can cause problems for users. One such problem is lack of memorability – the ability to find and go back to objects …

Design and implementation of non-photorealistic rendering techniques for 3D geospatial data
… information to be interactively highlighted in a context-dependent manner. Approaches in non-photorealistic renderings particularly consider a user's task and camera perspective when attempting optimal expression, recognition, and communication of important or prioritized information. However, the …

Developing an interactive overview for non-visual exploration of tabular numerical information
… making use of proprioception to maintain contextual information during exploration (non-visual focus+context), vibrotactile data annotations (EMA-Tactons) that can be used as external memory aids to prevent high mental workload levels, and speech synthesis to access detailed information on …

Interactive Visualization Lenses:
… redesign of analysis tools. This thesis focuses on interactive magic lenses, specialized locally applied tools that temporarily manipulate the visualization. These may include magnification of focus regions but also more graph-specific functions such as pulling in neighboring nodes or …

Multi-scale representations of virtual 3D city models
… technique is demonstrated with applications from focus+context visualization, out-of-core terrain rendering, and information visualization. This thesis presents components for the creation of abstract representations of virtual 3D city and landscape models. Re-using visual language from …
