Walk2Map: Extracting Floor Plans from Indoor Walk Trajectories
Claudio Mura, Renato Pajarola, Konrad Schindler +1
Recent years have seen a proliferation of new digital products for the efficient management of indoor spaces, with important applications like emergency management, virtual propert…
LOCALIS: Locally-adaptive Line Simplification for GPU-based Geographic Vector Data Visualization
Alireza Amiraghdam, Alexandra Diehl, Renato Pajarola
Visualization of large vector line data is a core task in geographic and cartographic systems. Vector maps are often displayed at different cartographic generalization levels, trad…
Visualization of High-dimensional Scalar Functions Using Principal Parameterizations
Rafael Ballester-Ripoll, Renato Pajarola
Insightful visualization of multidimensional scalar fields, in particular parameter spaces, is key to many fields in computational science and engineering. We propose a principal c…
TTHRESH: Tensor Compression for Multidimensional Visual Data
Rafael Ballester-Ripoll, Peter Lindstrom, Renato Pajarola
Memory and network bandwidth are decisive bottlenecks when handling high-resolution multidimensional data sets in visualization applications, and they increasingly demand suitable…
Equalizer 2.0 - Convergence of a Parallel Rendering Framework
Stefan Eilemann, David Steiner, Renato Pajarola
Developing complex, real world graphics applications which leverage multiple GPUs and computers for interactive 3D rendering tasks is a complex task. It requires expertise in distr…
Tensor Approximation of Advanced Metrics for Sensitivity Analysis
Rafael Ballester-Ripoll, Enrique G. Paredes, Renato Pajarola
Following up on the success of the analysis of variance (ANOVA) decomposition and the Sobol indices (SI) for global sensitivity analysis, various related quantities of interest hav…
Sobol Tensor Trains for Global Sensitivity Analysis
Rafael Ballester-Ripoll, Enrique G. Paredes, Renato Pajarola
Sobol indices are a widespread quantitative measure for variance-based global sensitivity analysis, but computing and utilizing them remains challenging for high-dimensional system…
Visualizing Flat Spacetime: Viewing Optical versus Special Relativistic Effects
Don V. Black, M. Gopi, F. Wessel +2
A simple visual representation of Minkowski spacetime appropriate for a student with a background in geometry and algebra is presented. Minkowski spacetime can be modeled with a Eu…
On best rank one approximation of tensors
S. Friedland, V. Mehrmann, R. Pajarola +1
In this paper we suggest a new algorithm for the computation of a best rank one approximation of tensors, called alternating singular value decomposition. This method is based on t…
