Fast Robust and Precise Shadow Algorithm for WebGL 1.0 Platform
(The Eurographics Association, 2015)
This paper presents fast and robust per-sample correct shadows for WebGL platform. The algorithm is based on silhouette shadow volumes and it rivals the standard shadow mapping performance. Our performance is usually ...
A Haptics-enabled Simulator for Transperineal Ultrasound-Guided Biopsy
(The Eurographics Association, 2015)
We present the development of a transperineal prostate biopsy, with high fidelity haptic feedback. We describe our current prototype, which is using physical props and a Geomagic Touch. In addition, we discuss a method for ...
Physical Space Requirements for Redirected Walking: How Size and Shape Affect Performance
(The Eurographics Association, 2015)
Redirected walking provides a compelling solution to explore large virtual environments in a natural way. However, research literature provides few guidelines regarding trade-offs involved in selecting size and layout for ...
Implementing Game Cinematography: Technical Challenges and Solutions for Automatic Camera Control in Games
(The Eurographics Association, 2015)
Cinematographic games are a rising genre in the computer games industry and an increasing number of titles published include some aspects of cinematography in the gameplay or the storytelling. At present state, camera ...
Guided Volume Editing based on Histogram Dissimilarity
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Segmentation of volumetric data is an important part of many analysis pipelines, but frequently requires manual inspection and correction. While plenty of volume editing techniques exist, it remains cumbersome and errorprone ...
Adaptive Recommendations for Enhanced Non-linear Exploration of Annotated 3D Objects
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
We introduce a novel approach for letting casual viewers explore detailed 3D models integrated with structured spatially associated descriptive information organized in a graph. Each node associates a subset of the 3D ...
Video Granular Synthesis
(The Eurographics Association, 2015)
This paper introduces a technique that enables the creative reshaping of one or more video signals based on granular synthesis techniques, normally applied only to audio signals. We demonstrate that a wide range of novel ...
Key-frame Based Spatiotemporal Scribble Propagation
(The Eurographics Association, 2015)
We present a practical, key-frame based scribble propagation framework. Our method builds upon recent advances in spatiotemporal filtering by adding key-components required for achieving seamless temporal propagation. To ...
Non-Photorealistic Rendering of Portraits
(The Eurographics Association, 2015)
We describe an image-based non-photorealistic rendering pipeline for creating portraits in two styles: The first is a somewhat ''puppet'' like rendering, that treats the face like a relatively uniform smooth surface, with ...
Evaluating 2D Flow Visualization Using Eye Tracking
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Flow visualization is recognized as an essential tool for many scientific research fields and different visualization approaches are proposed. Several studies are also conducted to evaluate their effectiveness but these ...
