Real or virtual large-scale structure?

Real or virtual large-scale structure?

Modeling the development of structure in the universe on galactic and larger scales is the challenge that drives the field of computational cosmology. Here, photorealism is used as a simple, yet expert, means of assessing the degree to which virtual worlds succeed in replicating our own.

Rendering environmental voice reverberation or large-scale distributed virtual worlds

We propose an approach that can render environmental audio effects for a large number of concurrent voice users immersed in a large distributed virtual world. In an off-line step, our approach efficiently computes acoustic similarity measures based on average path length, reflection direction and diffusion throughout the environment. The similarity measures are used to adaptively decompose the ...

Networking Large-Scale Virtual Environments

The virtual environment research community is focusing on the human-computer interaction model for fully-articulated 3D humans in the networked virtual environment. As that works moves forward, there is the desire to internetwork large numbers of players. The NPSNET Research Group is in the forefront of that work and is focusing on the network and software architecture necessary to support larg...

As real as real? Macroeconomic behavior in a large-scale virtual world

This article proposes an empirical test of whether aggregate economic behavior maps from the real to the virtual. Transaction data from a large commercial virtual world – the first such data set provided to outside researchers – is used to calculate metrics for production, consumption and money supply based on real-world definitions. Movements in these metrics over time were examined for consis...
