Virtual Reality Programming in Oz

To handle the complexity of virtual reality (VR) applications it is desirable to use a high level language. Languages such as Lisp, Prolog and Smalltalk do not support concurrency, reactivity and real-time control which are vital for VR-applications. However the new concurrent constraint programming paradigm in general, and Oz in particular supports these requirements. Oz is designed to support multiple concurrent agents, which makes it extremely well-suited for VR-applications. We have therefore implementeda basic interface between Oz and a toolkit for building distributed VR applications, DIVE. Furthermore we developed a higher level layer for supporting agent abstractions. 1. introduction DIVE [ACHS93] (Distributed Interactive Virtual Environment) is a tool kit for building distributed VR applications in a heterogeneous network environment. DIVE allows a number of users and applications to share a virtual environment where they can interact and communicate in real-time. This virtua..
