Surface flow phenomena, such as rain water flowing down a tree trunk and progressive water front in a shower room, are common in real life. However, compared with the 3D spatial fluid flow, these surface flow problems have been much less studied in the graphics community. To tackle this research gap, we present an efficient, robust and high-fidelity simulation approach based on the shallow-wate...

Real-time simulation of fur is a key element inmany virtual reality applications. However, it is still difficult to simulate effects of fur animation in real-time. In this paper, we propose an interactive fur simulation method, to calculate effects of external forces, such as wind and gravity, and direct manipulation for real-time interactive animation. The proposed method consists of two layer...

We present a method for realistic rendering and simulation of human hair in real-time, which is suitable for the use in complex virtual reality applications. Neighbouring hairs are combined into wisps and animated with our cantilever beam based simulation system, which runs numerically stable and with interactive update rates. The rendering algorithm utilizes latest graphics hardware features a...

Generationg realistic real-time cloth effects on-the-fly for interactive environments, such as games, is challanging and interesting. This article gives a practical explanation for students to enable them to integrate cloth effects into their demos. We explain the principles, computational overheads, and numerical approximations, necessary for achieving an asthetically pleasing realistic intera...

We present a system for simulating crowd behavior in emergency scenarios, specifically, the evacuation of buildings. We use a combination of techniques from robot motion planning, collision detection and response, particle systems, and group behavior. Our method initially builds a roadmap of the environment using PRMs, and computes the path to closest exits on the roadmap. The virtual agents mu...

This paper describes a debugging environment for real-time applications that supports the querying of the elapsed time at break-points. The environment employs hardware simulation at the level of processor cycles. The hardware simulation is limited only to the aspects relevant to processor cycle accounting and includes instruction caching, instruction frequency accounting, and instruction pipel...

Typical vehicle simulations require numerical integration at an integration time step no larger than 0.01 seconds, usually less than half that time. This does not leave enough time to carry out the complex calculations required for detailed collision calculations in real time. This paper presents a method that strikes a compromise, which, although not carrying all the detail necessary for very ...

model predictive controller is widely used in industrial plants. uncertainty is one of the critical issues in real systems. in this paper, the direct adaptive simplified model predictive control (smpc) is proposed for unknown or time varying plants with uncertainties. by estimating the plant step response in each sample, the controller is designed and the controller coefficients are directly ca...

In this document we studied more in detail the Performances of the vertical handover in the networks WLAN, WiMAX, UMTS before studying of it the Procedure of Handoff Vertical, the whole buckled by simulations putting forward the performances of the handover in the heterogeneous networks. The goal of Vertical Handover is to carry out several accesses in real-time in the heterogeneous networks. T...
