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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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. ...

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 ...
