DLoVe: using constraints to allow parallel processing in multi-user virtual reality

In this paper, we introduce DLoVe, a new paradigm for designing and implementing distributed and nondistributed virtual reality applications, using one-way constraints. DLoVe allows programs written in its framework to be executed on multiple computers for improved performance. It also allows easy specification and implementation of multi-user interfaces. DLoVe hides all the networking aspects of message passing among the machines in the distributed environment and performs the needed network optimizations. As a result, a user of DLoVe does not need to understand parallel and distributed programming to use the system; he or she needs only be able to use the serial version of the user interface description language. Parallelizing the computation is performed by DLoVe, without modifying the interface description.
