Software Components

• Server - handles all relevant data in an multi-user environment: session management, event distribution, data storage, user management, 3D space representation, and all other application (aka bussines) logic.
  
• Plugins - represent some other software as an object in 3d space. Here is an example showing AliceBot server (blonde) and entrance to antoher VRSpace server (gate).
  
• Client - responsible for user interaction, presentation, including presentation logic.
  
• Utilities - intended to make software and community maintenance easier. Most important is Chisel, VRML optimizer by Trapezium, used to publish 3d content to the server.
  
  
  

Technology
VRSpace uses only open standards:

• Java at both client and server side
  
• JavaScript and VRML97 at client side
  
• Any SQL database or no database at all at server side
  

However, client/server communication protocol is pure ascii. At least until this protocol is respected, client can be written in anything - it even may not have the screen output. For more details regarding chosen languages see FAQ.
