Filtering Environment Illumination for Interactive Physically-Based Rendering in Mixed Reality
(The Eurographics Association, 2015)
Physically correct rendering of environment illumination has been a long-standing challenge in interactive graphics, since Monte-Carlo ray-tracing requires thousands of rays per pixel. We propose accurate filtering of a ...
Semi-Automatic Digital Epigraphy from Images with Normals
(The Eurographics Association, 2015)
We present a semi-automated system for converting photometric datasets (RGB images with normals) into geometry-aware non-photorealistic illustrations that obey the common conventions of epigraphy (black-and-white archaeological ...
Towards Understanding Enjoyment and Flow in Information Visualization
(The Eurographics Association, 2015)
Traditionally, evaluation studies in information visualization have measured effectiveness by assessing performance time and accuracy. More recently, there has been a concerted effort to understand aspects beyond time and ...
Mining Social Images to Analyze Routing Preferences in Tourist Areas
(The Eurographics Association, 2015)
Social media platforms provide a useful source of data for environmental planning. In the last years these data have been exploited to perform social behaviour analysis. This work uses the huge amount of georeferenced ...
Level-of-Detail Modal Analysis for Real-time Sound Synthesis
(The Eurographics Association, 2015)
Modal sound synthesis is a promising approach for real-time physically-based sound synthesis. A modal analysis is used to compute characteristic vibration modes from the geometry and material properties of scene objects. ...
On the Reproducibility of VisRuption: A Tool for Intuitive and Efficient Visualization of Airline Disruption Data
(The Eurographics Association, 2015)
Managing the vast amount of resources and processes of large airlines with several hundred aircraft and several thousand operated flights per day is a very complex task and makes computer-aided operation irreplaceable. ...
A Mixed Approach for the Evaluation of a Guided Exploratory Visualization System
(The Eurographics Association, 2015)
We summarise and reflect upon our experience in evaluating a guided exploratory visualization system. Our system guides users in their exploration of multidimensional datasets to pertinent views of their data, where the ...
Fast Multiplexed Acquisition of High-dynamic-range Material Appearance
(The Eurographics Association, 2015)
There is tremendous demand for digital representations that allow for materials to be re-lit under as wide a range of illumination scenarios as possible. It is therefore desirable to capture the entire dynamic range of a ...
Integrating Predictions in Time Series Model Selection
(The Eurographics Association, 2015)
Time series appear in many different domains. The main goal in time series analysis is to find a model for given time series. The selection of time series models is done iteratively based, usually, on information criteria ...
MBVH Child Node Sorting for Fast Occlusion Test
(The Eurographics Association, 2015)
Optimal BVH layout differs among ray types. To accelerate shadow rays, the use of a specialized traversal order, optionally with an additional data structure has been proposed. In this paper we show how sorting child nodes ...
