Improved Sparse Seeding for 3D Electrostatic Field Lines
(The Eurographics Association, 2015)
We present an improved seeding strategy for sparse visualization of electrostatic fields. By analyzing the curvature of the field lines, we extract points of extremal field strength between charges of different sign and ...
OceanPaths: Visualizing Multivariate Oceanography Data
(The Eurographics Association, 2015)
Geographical datasets are ubiquitous in oceanography. While map-based visualizations are useful for many different domains, they can suffer from cluttering and overplotting issues when used for multivariate data sets. As ...
A Quality-Preserving Cartesian to Body-Centered Cubic Downsampling Transform
(The Eurographics Association, 2015)
The body-centered cubic lattice is the optimal sampling lattice in three dimensions. However, most volumetric datasets are acquired on the well-known Cartesian cubic lattice. In order to leverage the approximation capabilities ...
