... A virtual world is a computer-generated environment that simulates a three-dimensional space, often inhabited by digital representations of users known as avatars. In a virtual world, participants can interact with each other and the environment in ways that mimic real-life interactions. Virtual worlds can serve various purposes, including socializing, entertainment, education, training, research, creativity, and more.
    Key features:
  • 3D Environment: Virtual worlds typically feature a three-dimensional space with objects, landscapes, and structures that users can explore and interact with.
  • Avatars: Participants create avatars, which are digital personas that represent them in the virtual world. Avatars can be customized to reflect individual preferences and appearances.
  • Interaction: Users can navigate the virtual environment, communicate with others through text or voice chat, collaborate on tasks, and perform various actions, such as picking up objects, building structures, or participating in activities.
  • Real-time Interactivity: Virtual worlds operate in real-time, allowing participants to interact with each other and the environment instantaneously.
  • Content: Many virtual worlds enable users to create and modify their own content, such as buildings, objects, clothing, and animations. This user-generated content contributes to the richness and diversity of the virtual environment.
  • Persistence: Virtual worlds often have a persistent nature, meaning that changes made by users persist even after they log out. This allows for ongoing development and interaction within the virtual space.
  • Social Interaction: One of the primary draws of virtual worlds is the opportunity for social interaction. Users can meet, communicate, and build relationships with others from around the world.
  • Diverse Applications: Virtual worlds have been used for a wide range of applications, including gaming, social networking, virtual events, education, training simulations, architectural visualization, scientific research, and therapeutic interventions.
... OpenSimulator (OpenSim) is an open-source platform for creating and operating virtual worlds. It allows users to build, customize, and interact within the 3D virtual environments. These virtual worlds can be used for various purposes, including education, training, simulation, social interaction, gaming, and more. OpenSimulator is similar in concept to Second Life, a popular commercial virtual world, but it provides users with the ability to set up their own virtual world servers and tailor the environment to their specific needs.
    Key features:
  • Environment Creation: OpenSim allows users to design and build 3D environments using a range of tools and scripting languages. This enables the creation of immersive landscapes, buildings, objects, and avatars.
  • User Interaction: Users can navigate, interact, and communicate with other participants within the virtual world. Avatars represent users, and they can move around, chat, collaborate, and engage in various activities.
  • Customization and Scripting: OpenSim provides scripting capabilities that allow users to program behaviors and interactions within the virtual world. This allows for creating dynamic and interactive experiences.
  • Multi-User Environments: OpenSim supports multiple users accessing a virtual world simultaneously. Suitable for social interactions, events, meetings, and collaborative projects.
  • Integration with Web and External Systems: OpenSimulator can be integrated with external systems,databases, and web services, enabling a wide range of applications such as virtual training simulations, educational environments, and virtual exhibitions.
  • Open Source and Extensible: OpenSimulator is open-source software, which means its source code is freely available for modification and enhancement. This encourages a community of developers to contribute and extend its capabilities.
  • Distributed Architecture: OpenSim allows for the creation of interconnected grids or standalone regions, providing flexibility in how the virtual worlds are structured and managed.
