A New Direct Manipulation Technique for Immersive 3D Virtual Environments
(The Eurographics Association, 2014)
In this paper, we introduce a new 7-Handle manipulation technique for 3D objects in immersive virtual environments and its evaluation. The 7-Handle technique includes a set of seven points which are flexibly attached to ...
Large-scale Immersive Reconstitution of a Neolithic Corbel Dome
(The Eurographics Association, 2012)
We propose a workflow of tools and procedures to reconstruct an existing archaeological site as a virtual 3D reconstitution in a large scale immersive system. This interdisciplinary endeavor, gathering archaeologists and ...
Efficient Composition for Virtual Camera Control
(The Eurographics Association, 2012)
Automatically positioning a virtual camera in a 3D environment given the specification of visual properties to be satisfied (on-screen layout of subjects, vantage angles, visibility) is a complex and challenging problem. ...
On the Value of Multi-Volume Visualization for Preoperative Planning of Cerebral AVM Surgery
(The Eurographics Association, 2012)
Surgical treatment of cerebral arteriovenous malformations (AVMs) requires thourough preoperative planning for the intervening neurosurgeon. The goal of such planning is to gain a precise understanding of the patho-anatomy ...
Atomistic Visualization of Mesoscopic Whole-Cell Simulations
(The Eurographics Association, 2012)
Molecular visualizations are a principal tool for analyzing the results of biochemical simulations. With modern GPU ray casting approaches it is only possible to render several millions of atoms at interactive frame rates ...
Sketch-based Image-independent Editing of 3D Tumor Segmentations using Variational Interpolation
(The Eurographics Association, 2012)
In the past years sophisticated automatic segmentation algorithms for various medical image segmentation problems have been developed. However, there are always cases where automatic algorithms fail to provide an acceptable ...
An Efficient Interpolation Approach for Low Cost Unrestrained Gaze Tracking in 3D Space
(The Eurographics Association, 2016)
We present a first attempt to use interpolation based approach to combine a mobile eye tracker with an external tracking system to obtain a 3D gaze vector for a freely moving user. Our method captures calibration points ...
Visual Attention to Wayfinding Aids in Virtual Environments
(The Eurographics Association, 2013)
In an empirical evaluation, we examined participants' visual attention allocation to a dynamic wayfinding map in a complex simulation meant to educate medical practitioners in a hand hygiene protocol. Complex virtual ...
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 ...
