Auto-Tilt Photography
(The Eurographics Association, 2011)
Tilt-shift camera lenses are a powerful artistic tool to achieve effects like selective focus with very shallow depth of field. Typically they are used by professional photographers only, which is due to the high cost and ...
Trajectory Density Projection for Vector Field Visualization
(The Eurographics Association, 2013)
Trajectory visualization is an important tool to capture intrinsic characteristics of vector fields. However, often this class of geometric visualization suffers from visual clutter due to the number of curves that occlude ...
Rasterizing and antialiasing vector line art in the pixel art style
(ACM, 2013)
Pixel artists rasterize vector shapes by hand to minimize artifacts at low resolutions and emphasize the aesthetics of visible pixels. We describe Superpixelator, an algorithm that automates this process by rasterizing ...
On the Reproducibility of Line Integral Convolution for Real-Time Illustration of Molecular Surface Shape and Salient Regions
(The Eurographics Association, 2015)
In this paper, we discuss the reproducibility of our work presented at EuroVis 2014 [LKEP14], which describes an illustrative rendering method tailored to molecular surfaces.We distinguish between the reproducibility of ...
Interactive GPU-based Visualization of Scalar Data with Gaussian Distributed Uncertainty
(The Eurographics Association, 2015)
We present a GPU-based approach to visualize samples of normally distributed uncertain, three-dimensional scalar data. Our approach uses a mathematically sound interpolation scheme, i.e., Gaussian process regression. The ...
Towards Efficient Online Compression of Incrementally Acquired Point Clouds
(The Eurographics Association, 2014)
We present a framework for the online compression of incrementally acquired point cloud data. For this, we extend an existing vector quantization-based offline point cloud compression algorithm to handle the challenges ...
Revisiting Perceptually Optimized Color Mapping for High-Dimensional Data Analysis
(The Eurographics Association, 2014)
Color is one of the most effective visual variables since it can be combined with other mappings and encodeinformation without using any additional space on the display. An important example where expressing additionalvisual ...
Community-driven Generation of 3D and Augmented Web Content for Archaeology
(The Eurographics Association, 2014)
Heritage sites (such as prehistoric burial cairns and standing stones) are prolific in Europe; although there is a wish to scan each of these sites, it would be time-consuming to achieve. Citizen science approaches enable ...
Towards Combining Attribute-based and Time Series-based Visual Querying
(The Eurographics Association, 2016)
We present a concept for the visual-interactive definition of meaningful subsets in data sets comprising multivariate attributes and time series data. Based on a generalization of requirements of a real-world user group, ...
