Occlusion-Free Conformal Lensing for Spatiotemporal Visualization in 3D Urban Analytics
Roberta Mota, Julio D. Silva, Fabio Miranda +3
The visualization of temporal data on urban buildings, such as shadows, noise, and solar potential, plays a critical role in the analysis of dynamic urban phenomena. However, in de…
Designing Reality-Based VR Interfaces for Geological Uncertainty
Roberta Mota, Ehud Sharlin, Usman Alim
Inherent uncertainty in geological data acquisition leads to the generation of large ensembles of equiprobable 3D reservoir models. Running computationally costly numerical flow si…
Virtual Reality Lensing for Surface Approximation in Feature-driven DVR
Roberta Mota, Ehud Sharlin, Usman Alim
We present a novel lens technique to support the identification of heterogeneous features in direct volume rendering (DVR) visualizations. In contrast to data-centric transfer func…
Spatially-Embedded Lens Visualization: A Design Space
Roberta Mota, Ehud Sharlin, Usman Alim
Lens visualization has been a prominent research area in the visualization community, fueled by the continuous need to mitigate visual clutter and occlusion resulting from the incr…
