 '''Abstract:''' ''We developed a conversion system to load OpenSimulator Archive (.oar) files into Unity. This system allows the user to load world data jointly created in OpenSimulator into Unity on a region-by-region basis, and to ultimately output the data from Unity in a variety of formats. These features allow us to treat the pairing of OpenSimulator and Unity as a shared development environment, which simplifies the low-cost creation of 3D spatial visualization data.''

 '''Abstract:''' ''Collaborative 3D virtual spaces and their services are often too heavy for a mobile device to handle. The burden of such services is divided between extensive amounts of data, which need to be downloaded prior to using the service, and the complexity of the resulting graphical rendering process. In this paper, a proxy based architecture for collaborative virtual spaces is used to manipulate graphical data demand-time to favor both network bandwidth usage and graphical rendering process. In addition, a proof of concept test is shown, regarding how the simplification process gains savings for different client device profiles, including laptops, tablets and mobile devices.''

 '''Abstract:''' ''An “agent” in a computer simulation is an object with a dynamic model driving its actions. There are different classifications for agents, for example: autonomous, intelligent, and software. A cell within a cellular automaton might be considered an agent with the complete environment being a multi-agent system. An object containing an artificial intelligence could also be considered an agent. Our purpose is to introduce the “personal” aspect of agents through first-person perspective—by becoming one of the agents in the simulation. When a level of presence on the part of the human’s relationship to the agent is incorporated in this fashion, we must incorporate methods found typically within multi-user virtual environments. This tutorial is centered on one particular open-source, multi-user, virtual environment system called OpenSimulator (or OpenSim). We introduce OpenSim to allow the reader an opportunity for understanding how this software is used within the context of agentbased computer simulations''

-'''Abstract:''' ''This paper presents a reality-virtual fusional campus environment. It is an online 3D platform with some aspects of real information merged together. The whole platform is based on OpenSimulator with detailed geo-models to represent the university campus. Some preliminary experiments were done to integrate the realistic information with the virtual campus for making the geo-environment not only with detailed indoor and outdoor models, but also with the real representations of the physical world. The overall motivation is to provide a framework with strong support for reality-virtuality fusional modeling in a collaborative 3D online platform for research purposes.''

 '''Abstract:''' ''This paper presents a technical performance evaluation of OpenSimulator as an alternative platform to Second Life, for virtual design studios. A number of issues that are critical for conducting virtual design studios were investigated through a series of tests and reflections from a Visual Training class. A performance test was also carried out in order to test server load against computer memory. These findings will provide valuable understanding to academics looking to use similar environments to Second Life for virtual design studio.''

It includes: analysis of various information sources and databases about the places of residence of famous people and their activities during their stay; creation of preliminary drawings and cartographic images of the territory; development of photorealistic three-dimensional models. Creating a virtual space in the form of a Virtual Museum is carried out using an open source software platform OpenSimulator, which is a server platform for 3D virtual worlds. In this study, we have made a virtual reconstruction of V I Vernadskiy’s family estate in the village of Vernadovka in Pitchaevskiy district of Tambov region related to objects, public and professional activities of an outstanding Russian scientist V I Vernadskiy.''

 '''Abstract:''' ''3D interface devices are being announced as rendering virtual world navigation easier. We have prepared a usability testing framework for two such devices, SpaceNavigator and SpacePilot PRO, manufactured by 3Dconnexion. The paper summarizes the underlying concepts of usability testing and links them to the requirements of a virtual world 3D interface context. We detail the metrics to be employed and the reasoning behind their selection, and the planning which yielded the actual framework to be used for conducting the 3D interface usability tests in the Second Life virtual world.''

 '''Abstract:''' ''This compatibility study examines potential interoperability between OpenSimulator, a free, server-based 3D virtual world simulator, and a set of DND/CF simulation tools. Interoperability is assessed in four areas: simulation operation, terrain models, 3D models, and human factors tools. Simulation technologies assessed for compatibility are the DIS and HLA simulation protocols, the Unity game engine, the VBS2 serious game, SmartMarine 3D and SmartPlant 3D CAD applications, the HumanCAD anthropomorphic articulation simulator, and the IPME task modelling and crew simulator. OpenSimulator does not use DIS or HLA, so it is not currently able to directly interface with any simulator that uses these industry standards. Terrain data compatibility is limited by the RAW format used by OpenSimulator. Unity is able to provide the required height-map portion of the terrain while VBS2 cannot produce a compatible terrain component directly. The set of DND/CF tools that use model-based assets can, in most cases, be converted to the COLLADA format which OpenSimulator is compatible with. HumanCAD also has the ability to export model formats that can be converted to COLLADA. IPME can communicate over TCP/IP connections and so an interface to OpenSimulator could be developed. Overall, OpenSimulator is compatible with the set of DND/CF tools examined in terms of its ability to re-use 3D model content originally developed for these tools. Some compatibility exists with respect to re-use of terrain data. But there is marginal to no compatibility with respect to operating OpenSimulator using the tools studied.''

 '''Abstract:''' ''This paper describes an implementation of geo-fence in an online Virtual Geographic Environment platform, which is based on OpenSimulator with detailed geo-models to represent the real scene. Virtual sensors are used to get its position and estimate its relationships with geo-fence. Geo-fence is visualized to give the users an intuitional feeling. Some preliminary experiments were done to test the virtual sensors in the virtual environment. The overall motivation is to provide an exploration for simulating and testing sensors in a 1:1 reconstructing virtual world of the reality for research purposes''

		+	'''Abstract:''' ''This paper aims to aid in the development of interactivity in virtual worlds, especially within the context of a virtual museum that serves the purpose of introducing its visitors to computing and basic electricity. We opted for the use of software agents with instructional and interactive purposes, which were personified as intelligent avatars serving as guides to a museum. This paper presents both a virtual 3D museum about the history of computing, developed using the OpenSimulator virtual worlds platform, where its 3D modeling and development tools were used with the help of scripts, as well as the focus of the project, which is the development of software agents. For the sake of achieving the objectives of this work, a research was conducted with a case study in order to verify whether the use of an intelligent agent in a virtual world can facilitate or support in the process of teaching and learning providing knowledge about the historical part of computing. The construction of this environment, integrated with an intelligent agent named AGIMC (the Portuguese acronym for Intelligent Agent of the Museum of Computing) used the public web server pandorabots. To verify the feasibility of using the environment, a case study was carried out, which demonstrated that the use of these environments does contribute as a mean to support teaching, but there are also some technological limitations that may hinder its practical use in the educational context. An assessment was carried out with IFRS (Federal Institute of Rio Grande do Sul). The results obtained during the evaluation with the students met our expectations, obtaining good results and indications that the agent did support the student’s conception of knowledge in the discipline introduction to computing, despite some difficulties found in its implementation.''
