Semi-sharp Creases on Subdivision Curves and Surfaces
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
We explore a method for generalising Pixar semi-sharp creases from the univariate cubic case to arbitrary degree subdivision curves. Our approach is based on solving simple matrix equations. The resulting schemes allow for ...
A Variational Taxonomy for Surface Reconstruction from Oriented Points
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
The problem of reconstructing a watertight surface from a finite set of oriented points has received much attention over the last decades. In this paper, we propose a general higher order framework for surface reconstruction. ...
Line-based rendering with truchet-like tiles
(ACM, 2014)
We explore the use of Truchet-like tiles (tiles with half area shaded) for single-tone (monochrome) line-based rendering of maps. We borrow concepts from information theory to develop some qualitative and quantitative ...
Computational rim illumination with aerial robots
(ACM, 2014)
Lighting plays a major role in photography. Professional photographers use elaborate installations to light their subjects and achieve sophisticated styles. However, lighting moving subjects performing dynamic tasks presents ...
Collaborative filtering of color aesthetics
(ACM, 2014)
This paper investigates individual variation in aesthetic preferences, and learns models for predicting the preferences of individual users. Preferences for color aesthetics are learned using a collaborative filtering ...
The monumental geometry of E Pluribus Unum
(ACM, 2014)
We describe the conception and construction of E Pluribus Unum, a large-scale artwork that combines text and geometry to depict over a million names of global organizations dedicated to social and environmental causes. The ...
What does water look like?
(ACM, 2014)
What makes images of water look like water? We conducted four psychophysical experiments to isolate perceptual qualities that make water easy to recognize. Water recognition is facilitated by colour and by three patterns ...
Frayed cell diagrams
(ACM, 2014)
Tesselation-based or area-based visual representations are common to many artistic or visualization applications. For example, Voronoi art uses a space-filling tessellation of the image by Voronoi cells. We present frayed ...
Visual-interactive Exploration of Interesting Multivariate Relations in Mixed Research Data Sets
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
The analysis of research data plays a key role in data-driven areas of science. Varieties of mixed research data sets exist and scientists aim to derive or validate hypotheses to find undiscovered knowledge. Many analysis ...
Visual Analysis of Time-Series Similarities for Anomaly Detection in Sensor Networks
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
We present a system to analyze time-series data in sensor networks. Our approach supports exploratory tasks for the comparison of univariate, geo-referenced sensor data, in particular for anomaly detection. We split the ...
