In this paper, we present the design and implementation of a VRML97 multi-user layer, which is introduced in the EVE distributed virtual reality platform. Though other approaches use a VRML node insertion mechanism, such as VSPLUS, or a substitution mechanism, such as SPIN-3D, our approach uses a removal mechanism. Main consideration of our multi-user extension is the ease of transforming singl...

The virtual reality modeling language (VRML) [1] is quickly growing in use and popularity. VRML may help to push fast 3D graphics onto most desktops and into most homes within the next few years. But are people ready to browse virtual-worlds in the same way that they currently browse flatland web pages, and more importantly, are virtual-worlds and virtual-world browsers ready for people ? There...

Research into virtual worlds demonstrates that to successfully use virtual world platforms in different disciplines, certain limitations and potential difficulties of these platforms must be overcome. The current study extends previous research by investigating problems in integrating virtual worlds in education with a longitudinal observation of two cases and in perspectives of designers, prac...

Virtual reality is an effective way (in many situations) for creating 3D visualisations, although the visualisations need to be designed with both 3D and virtual reality in mind to be most useful. Many issues are related to virtual realities, although these are often overlooked by users due to the issues being tightly integrated with the virtual worlds. Even though users can disregard such issu...

Virtual worlds (often referred to as 3D3C for 3D visualization & navigation and the 3C’s of Community, Creation and Commerce) integrate existing and emerging (media) technologies (e.g. instant messaging, video, 3D, VR, AI, chat, voice, etc.) that allow for the support of existing and the development of new kinds of networked services. The emergence of virtual worlds as platforms for networked s...

Simulation is the process that allows the study of a physical system, replacing it by another, more suitable for measure or observation. Some simulations work better using Virtual Reality (VR) techniques [1][2][3] where virtual worlds exist only in the memory of a computer. The user interacts with these virtual worlds by means of different types of devices (from 3D mouses to haptic devices), th...

Currently, we use many definitions with diffuse boundaries: Web 2.0 (Social Networks), Web 3.0 (Semantic Web), Web 3D (Metaverses, Virtual Worlds, Mirror Worlds), Recommendation Systems, Augmented Reality, Geo-location... In this paper we explore the possibilities of the combined use of these concepts, we introduce the concept of VARD (Virtual Augmented Reality Device) and show interoperability...
