Open Wonderland (originally Project Wonderland) is an open-source toolkit written in Java for creating collaborative 3D virtual worlds. Within those worlds, users can communicate with high-fidelity, immersive audio, share live desktop applications and documents in addition to conducting real business.
Animations, sounds, lighting, and other aspects of the virtual world can interact with the user or may be triggered by external events such as timers. A special Script Node allows the addition of program code (e.g., written in Java or ECMAScript) to a VRML file. VRML files are commonly called "worlds" and have the .wrl extension (for example ...
Users exploring the world with their avatars in Second Life. A virtual world (also called a virtual space or spaces) is a computer-simulated environment [1] which may be populated by many simultaneous users who can create a personal avatar [2] and independently explore the virtual world, participate in its activities, and communicate with others.
Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers write once, run anywhere (), [16] meaning that compiled Java code can run on all platforms that support Java without the need to recompile. [17]
[2] [3] Ideally, this meant that a Java program could be developed on any device, compiled into standard bytecode, and be expected to run on any device equipped with a Java virtual machine (JVM). The installation of a JVM or Java interpreter on chips, devices, or software packages became an industry standard practice.
The more recent Java version, WorldWind Java, is cross platform, a software development kit (SDK) aimed at developers and, unlike the old .NET version, not a standalone virtual globe application in the style of Google Earth. The WorldWind Java version was awarded NASA Software of the Year in November 2009. [3]
Users can place objects from Alice's gallery into the virtual world that they have imagined, and then they can program by dragging and dropping tiles that represent logical structures. Additionally, the user can manipulate Alice's camera and lighting to make further enhancements. Alice can be used for 3D user interfaces.
A Java virtual machine (JVM) is a virtual machine that enables a computer to run Java programs as well as programs written in other languages that are also compiled to Java bytecode. The JVM is detailed by a specification that formally describes what is required in a JVM implementation.
