We describe a software book model that emulates a range of properties associated with physical books— analog page turning, visual location cues, bookmarks and annotations—and, furthermore, incorporates many advantages of digital environments—hyperlinks, multimedia, full-text search, automatic identification of synonyms, cross-referencing of key terms with an online encyclopedia, and an automati...

This paper describes an algorithm for automatically adapting existing animated behaviors to new actors with diierent physical characteristics. When simulation is used for animation, this is a diicult problem because a control system that is tuned for one actor will not work on an actor with diierent limb lengths, masses, or moments of inertia. The algorithm presented here adapts the control sys...

The Internet is a complex collection of various nodes which run independently. The hardware and software of nodes are quite diverse and these elements make the complexity of the Internet. It is difficult to model these behaviors, so we proposed and implemented StarBED, a large-scale testbed using general PCs and switches. Thus we created an environment for experiment using realistic nodes and s...

Engineering Department, Cambridge University, Cambridge CB2 1PZ, UK E-mail: [email protected] Carbon nanotubes (CNTs) are a fascinating subject for curiosity-driven research. But will they give rise to commercially viable applications? CNTs are rolled up sheets of sp2 bonded graphite with no surface broken bonds. Their possible applications1,2 arise from the remarkable properties of single-walle...

In this paper, we present a system for the implementation of a photorealistic avatar using video captured from a user . This is achieved by constructing the dynamic video texture map and combining it with the 3D mesh model of the user to render the photorealistic avatar. The dynamic video texture map reflects the user’s facial expressions and is generated by composing the cylindrical texture ma...

We present a comprehensive methodology for realistically animating liquid phenomena Physically accurate D mo tion is achieved by performing a two stage calculation over an arbitrary environment of static obstacles surrounded by uid A nite di erence approximation to the Navier Stokes equations is rst applied to a low resolution vox elized representation of the scene The resulting velocity and pr...

Film grain is the unique texture which results from the silver halide based analog photographic process. Film emulsions are made up of microscopic photo-sensitive silver grains, and the fluctuating density of these grains leads to what is known as film grain. This texture is valued by photographers and film directors for its artistic value. We present two implementations of a film grain renderi...

Modeling the Internet infrastructure is a challenging endeavor. Complex interactions between protocols, increasing traffic volumes and the irregular structure of the Internet lead to demanding requirements for the simulation developer. These requirements include implementation detail, memory efficiency and scalability, among others. We introduce a simulation model of the Border Gateway Protocol...
