Colosseum3D Authoring framework for Virtual Environments
(The Eurographics Association, 2005)This paper describes an authoring environment for real time 3D environments, Colosseum3D. The framework makes it possible to easily create rich virtual environments with rigid-body dynamics, advanced rendering using OpenGL ... -
Distributed Software-Based Volume Visualization in a Virtual Environment
(The Eurographics Association, 2005)In this paper we present our integration of volume rendering into virtual reality, combining a fast and flexible software implementation of direct volume rendering with the intuitive manipulation and navigation techniques ... -
Dynamic Bounding Volume Hierarchies for Occlusion Culling
(The Eurographics Association, 2005)We present an algorithm for rendering complex scenes using occlusion queries to resolve visibility. To organize objects in the scene, the algorithm uses a ternary tree which is dynamically modified according to the current ... -
Enhanced Hand Manipulation for Efficient and Precise Positioning and Release
(The Eurographics Association, 2005)Direct manipulation by hand is important in that it allows users to manipulate 3D virtual objects easily in an immersive virtual reality environment. Although direct hand manipulation is easy to understand and easy to use ... -
Evaluation of Collaborative Construction in Mixed Reality
(The Eurographics Association, 2005)Collaborative virtual and augmented reality are an active area of research and many systems supporting collaboration have been presented. Just like there are many different systems for VR and AR, there are many different ... -
Experience of a Hybrid Information Space between an Outdoor Field and an Immersive Virtual World
(The Eurographics Association, 2005)This paper proposes the concept of the hybrid information space that integrates the information seamlessly between the real world and the virtual world, and the prototype system was developed in which the immersive virtual ... -
Feature Tracking in VR for Cumulus Cloud Life-Cycle Studies
(The Eurographics Association, 2005)Feature tracking in large data sets is traditionally an off-line, batch processing operation while virtual reality typically focuses on highly interactive tasks and applications. This paper presents an approach that uses ... -
A Game Engine-based Multi-Projection Virtual Environment with System-Level Synchronization
(The Eurographics Association, 2005)In multi-projector displays, which surround users with high-resolution images, a PC-Cluster is often used for realistic and real-time image generation. However, developing applications that support parallel processing on ... -
Imperceptible Projection Blanking for Reliable Segmentation within Mixed Reality Applications
(The Eurographics Association, 2005)Applications that run in a projection-based mixed reality environment frequently require simultaneous image acquisition of the user by a camera. For later processing, very often a segmentation of the user s image is required, ... -
IntenSelect: Using Dynamic Object Rating for Assisting 3D Object Selection
(The Eurographics Association, 2005)We present IntenSelect, a novel selection technique that dynamically assists the user in the selection of 3D objects in Virtual Environments. Ray-casting selection is commonly used, although it has limited accuracy and can ... -
Interacting with Molecular Structures: User Performance versus System Complexity
(The Eurographics Association, 2005)Effective interaction in a virtual environment requires that the user can adequately judge the spatial relationships between the objects in a 3D scene. In order to accomplish adequate depth perception, existing virtual ... -
Language Learning in Virtual Environments: Bobo and Apples
(The Eurographics Association, 2005)Bobo and Apples is one of the prototype games within SAME4KIDS (Speech-based,Animated, Multilingual,Educational games for Kids, http://same4kids.sourceforge.net/ ), a multi-language and multi-purpose games project for ... -
Low-Cost, Portable, Multi-Wall Virtual Reality
(The Eurographics Association, 2005)Virtual reality systems make compelling outreach displays, but some systems highly suitable for outreach, notably the CAVE, have design features that make using them for that purpose inconvenient. In the case of the CAVE, ... -
Modeling of Trees with 3D Gestures and Growth Simulation
(The Eurographics Association, 2005)We propose a modeling system that enables users to create tree models with 3D gesture input. It generates tree models by using growth simulation based on the trunk or silhouette shapes of trees given by user gestures. The ... -
Näprä - Affordable Fingertip Tracking with Ultrasound
(The Eurographics Association, 2005)In this paper we present Näprä, a novel tracking device suitable for fine motor interaction. The motivation for building the device was the need to track users' fingertips in an immersive free-hand drawing environment. ... -
Optical Tracking and Calibration of Tangible Interaction Devices
(The Eurographics Association, 2005)In this paper, a novel optical tracking and object calibration system is presented for the recognition and pose estimation of tangible interaction devices for virtual and augmented reality systems. The calibration system ... -
Pseudo-Physical Interaction with a Virtual Car Interior in Immersive Environments
(The Eurographics Association, 2005)The use of Virtual Reality technology for the product engineering process in the automotive industry has a lot of potential in particular in the area of usability and reachability studies. We analyzed the manipulation ... -
Real-time Deformation of Detailed Geometry Based on Mappings to a Less Detailed Physical Simulation on the GPU
(The Eurographics Association, 2005)Modern graphics processing units (GPUs) can be effectively used to solve physical systems. To use the GPU optimally, the discretization of the physical system is often restricted to a regular grid. When grid values represent ... -
Reducing Fragmentation in Telecollaboration by Using IPT Interfaces
(The Eurographics Association, 2005)Telecommunication systems, such as AccessGrid, allow collaboration across a distributed team. However, these systems typically introduce fragmentation into the view of the shared environment. Many have found that IPT systems ... -
