In this article we describe stress nets, a technique for exploring 2D tensor fields. Our method allows a user to examine simultaneously the tensors' eigenvectors (both major ...
Direct volume rendering is a computationally intensive operation that has become a valued and often preferred visualization tool. For maximal data comprehension, interactive manip...
We propose an illumination invariant and rotation insensitive texture representation based on a Markovian textural model. A texture is aligned with its dominant orientation and te...
We present a method for automatically rendering pen-and-ink illustrations of trees. A given 3-d tree model is illustrated by the tree and a visual representation of the foliage us...
—We introduce a network visualization technique that supports an analytical method applied in the social sciences. Policy network analysis is an approach to study policy making s...
