Foil 18 DIS meets the Web in 1997 (II)

From Distributed Simulation (DIS,HLA) HPCC and the Object Web Visit to ARL Aberdeen -- June 5-6 97. by Wojtek Furmanski *
1 Recent software release from NPS (with GNU "copyleft") includes:
  • A subset DIS protocol implemented as a package of Java classes (currently functional are: Entity State PDU, Fire, Detonation, Comment).
  • A simple VRML2 based visualization which includes simple vehicles moving in 3D space with dead reckoning support
  • 'bridge' daemons based Java networking to bypass browser security constraints and to support multicasting.
2 The NPS prototype proves that a Web based DIS system can be built but it also points out several deficiencies of the current Web as a distributed simulation platform. We discuss in more detail the overall architecture of the NPS demo and we summarize the encountered technology problems on the next two foils.
