Abstract

Multilevel implementation of the dynamic virtual environment D. KoroSec, A. Holobar M. Divjak & D. Zazula Faculty of Electrical Engineering and Computer Science University of Maribor, Slovenia. Abstract Virtual environments (VEs) are nowadays often more than just static visualizations of 3D scenes in which user can navigate its avatar. From traditional applications in, for example, civil and machine engineering, 3D technology is moving forward to dynamic simulations and training systems. Unfortunately - there is still a lack of software standards that could be used to efficiently build such systems. VRML as probably the most standard technology for description of 3D scenes can add dynamic behaviour to 3D objects, but its implementation mechanisms, based on messaging, are rather crude. Three main levels exist: on the bottom simple deterministic behaviour can be hard-coded; medium level (scripting) then resolves many of the bottom level limitations; and finally, to create a complex system, separ
