Dynamic composition of behavior-rich VR content

Abstract

A novel approach to modeling and dynamic composition of behavior-rich interactive VR content is presented. The approach, called Beh-VR, enables dynamic generation of virtual scenes from arbitrarily selected sets of specifically designed reusable virtual objects, called VR-Beans. Presentation and behavior of the objects in virtual scenes is determined by associated scripts encoded in a high-level language called VR-BML. VR-Beans are compatible with existing scene description standards such as VRML/X3D, but are designed according to specific rules enabling the use of these objects in dynamically generated scenes. Further, to simplify the design of complex interactive VR scenes, VR content patterns are used.

Modelling Behaviour of Configurable VR Applications

“…This motivation lead to the development of the Flex-VR approach to building VR applications, in which content can be relatively easily created and modified by domain experts and common users [12,13] In Flex-VR, the VR application content is dynamically configured from reusable programmable content elements, called VR-Beans.Appearance and behaviour of the VR-Beans are controlled by high-level behaviour scripts.…”
