vrLib: A Designer Oriented Interaction and 3D User Interface Library
(The Eurographics Association, 2007)
In this paper we propose vrLib, a toolkit which aims to make 3D graphical user interface and interaction very easy to design in virtual environments. This project provides well known and new interaction techniques and ready ...
Requirements for Industrial Augmented Reality Tracking Systems - an Evaluation
(The Eurographics Association, 2007)
Industrial environments often have special requirements for AR systems and features are prioritized different than in scientific applications. The Volkswagen group (VW) wants to apply an AR-guided stud welding system for ...
Constraint Sets for Topology-changing Finite Element Models
(The Eurographics Association, 2007)
We propose constraint sets as an efficient data structure for topology-changing deformable tetrahedral meshes. Using constraint sets, data structure updates in case of topology changes are simple and efficient. The consistency ...
Learning from Painting: Perspective-dependent Geometry Deformation for Perceptual Realism
(The Eurographics Association, 2007)
Virtual environments and user interfaces in general can be improved by using the concept of Perceptual Realism, e.g. by means of non-photorealistic rendering techniques. The approach presented here follows a different path ...
An Immersive CAD Testbed
(The Eurographics Association, 2007)
Today Virtual Environments in industry are predominantly used for passive analysis of product or production data, mostly exported from CAD systems. To investigate on potentials of future immersive CAD-modeling and feasible ...
Gait Parameters while Walking in a Head-mounted Display Virtual Environment and the Real World
(The Eurographics Association, 2007)
Full-body motion tracking data was collected for six subjects during free walking. Each participant was asked to walk to a previously seen target under four experimental conditions: eyes closed within the real world, eyes ...
Hardware Accelerated Broad Phase Collision Detection for Realtime Simulations
(The Eurographics Association, 2007)
Broad phase collision detection is a vital task in most interactive simulations, but it remains computationally expensive and is frequently an impediment to efficient implementation of realtime graphics applications. To ...
3-D Reconstitution and Virtual Reality of World Heritage Site in Danger: the Citadel of Bam
(The Eurographics Association, 2007)
This paper presents research in progress on 3-D computer simulation and a virtual reality demonstration of a world heritage site that was destroyed in the earthquake (the citadel of Bam). In a comparative study with other ...
Virtual Adhesive: a Way to Handle Sticky Collisions in Surgical and Biological Simulators
(The Eurographics Association, 2007)
A variety of methods have been proposed to efficiently process collisions between deformable objects. The method presented in this paper allows to model sticky states between deformable objects with triangulated surfaces. ...
Occlusion-Based Snow Accumulation Simulation
(The Eurographics Association, 2007)
We present a fast technique for the simulation of accumulated snow. Our technique is based on two phenomena; local occlusion of small holes and ditches, and the global influence of a skylight. We use ambient occlusion to ...
