We present a new real-time hydraulic erosion simulation for Computer Graphics. In our system water runs over the surface and disintegrates the underlying layer of soil. The grit is simulated as a fluid with higher viscosity and moves on the ground of the water pool. When water evaporates, or the dissolved soil exceeds a critical level, the dissolved matter is deposited back on the ground for ac...

Di¤erential protection schemes for busbars, generators or transformers connect multiple current transformers in parallel across a common burden. This paper describes the techniques used to simulate such an arrangement in real time.

With the development of the simulation technique, deformable cloth simulation has become highly desired. It can be widely used in many fields such as game, animation, virtual surgery, etc. Real-time algorithm is the most urgent bottleneck problem that needs to be solved. This paper introduces a solution to implement deformable simulation of cloth in real time, accomplished through using a meshl...

OVERLAY MULTICAST FOR REAL-TIME DISTRIBUTED SIMULATION This report provides a top-level architecture for an overlay multicast service in support of distributed real-time virtual simulations over an open network environment. The top-level architecture for the overlay protocol was developed based on key concepts identified in the laboratory performance studies, the analytical model, and the studi...

The major concern in the construction industry in constructing tall structures is vibration due to wind and earthquake. Tuned mass dampers are an effective and practical ways to reduce the effect of vibration in structures. This thesis presents a tool, which simulates the effect of tuned mass dampers on the structure. This tool has been proposed to form a part of the website, moment.mit.edu. Ja...

We present a new adaptive model for real-time fluid simulation based on Smoothed Particle Hydrodynamics (SPH) framework. Unlike traditional time-consuming SPH methods, our model can simulate fluid at a considerably faster speed without losing realism. In our model, we first introduce the non-uniform particle system and propose a generalized distance field function which considers not only geome...

Cataract is a clouding of the eye’s natural lens, normally due to natural aging changes, and involving at least half of the population over 65 years. Cataract extraction is the only solution for restoring a clear vision, and nowadays is probably the most frequently practiced surgical procedure. This paper describes a novel virtual reality simulation system for cataract surgery training, involvi...

With the increasing role played by ultrasound in clinical diagnostics, ultrasound training in medical education has been becoming very important. The clinical routine is for ultrasound to be trained on real patients; therefore, monitored and guided examinations involving medical students are quite time constrained. To be realistically effective, a computerized ultrasound simulation would provid...

While virtual crowds are becoming common in non-real-time applications, the real-time domain is still relatively unexplored. In this paper we discuss the challenges involved in creating such simulations, especially the need to efficiently manage variety. We introduce the concept of levels of variety. Then we present our work on crowd behaviour simulation aimed at interactive real-time applicati...

Automated Planning has been an active research topic for more than thirty years but only recently has it started to move in the direction of combining planning and execution to achieve what is sometimes called as Intelligent Reactive Planning. We propose Simulation-Based Planning (SBP) as a new way to perform intelligent reactive planning. SBP |unlike most other planning systems|integrates simu...
