Multilevel Streaming for Out-of-Core Surface Reconstruction
(The Eurographics Association, 2007)
Reconstruction of surfaces from huge collections of scanned points often requires out-of-core techniques, and most such techniques involve local computations that are not resilient to data errors. We show that a Poisson-based ...
Galilean Invariant Extraction and Iconic Representation of Vortex Core Lines
(The Eurographics Association, 2005)
While vortex region quantities are Galilean invariant, most methods for extracting vortex cores depend on the frame of reference. We present an approach to extracting vortex core lines independently of the frame of reference ...
An Initial Evaluation of a Pen-Based Tool for Creating Dynamic Mathematical Illustrations
(The Eurographics Association, 2006)
MathPad2is a pen-based application prototype for creating mathematical sketches. Using a modeless gestural interface, it lets users make dynamic illustrations by associating handwritten mathematics with free-form drawings ...
An Optimized Soft Shadow Volume Algorithm with Real-Time Performance
(The Eurographics Association, 2003)
In this paper, we present several optimizations to our previously presented soft shadow volume algorithm. Our optimizations include tighter wedges, heavily optimized pixel shader code for both rectangular and spherical ...
WWW-Based Building Information System for "Domus Severiana" Palace at Palatine in Rome by Open Source Software
(The Eurographics Association, 2006)
The aim of this research project is the digital documentation of the "Domus Severiana" Palace at Palatine in Rome through the integration of geometrical 3D- and non-geometrical information. The great density of information ...
The Interaction Between Individuals' Immersive Tendencies and the Sensation of Presence in a Virtual Environment
(The Eurographics Association, 2000)
Witmer and Singer have developed a questionnaire for presence (PQ) as well as an immersive tendencies questionnaire (ITQ). Their research has shown that ITQ scores are positively correlated with PQ scores. This paper reports ...
Hardware-accelerated Extraction and Rendering of Point Set Surfaces
(The Eurographics Association, 2006)
Point-based models are gaining lately considerable attention as an alternative to traditional surface meshes. In this context, Point Set Surfaces (PSS) were proposed as a modeling and rendering method with important ...
Integrating Real-time Binaural Acoustics into VR Applications
(The Eurographics Association, 2004)
Common research in the field of Virtual Reality (VR) considers acoustic stimulation as a highly important necessity for enhanced immersion into virtual scenes. However, most common VR toolkits do only marginally support ...
An Innovative Design Approach to Build Virtual Environment Systems
(The Eurographics Association, 2003)
A Virtual Environment (VE) presents a complex problem with interesting non-trivial challenges for software development. The majority of existing systems supporting VE are based on monolithic architectures, making maintenance ...
Color Consistency for Digital Multi-Projector Stereo Display Systems : The HEyeWall and The Digital CAVE
(The Eurographics Association, 2003)
Digital projectors have a significant advantage over CRTs for IPT setups: brightness. But they also have a number of disadvantages, one of which is color consistency. This problem is exacerbated when using the Infitec ...
