In this work, the design of a low-cost, field programmable gate array (FPGA)-based digital hardware platform that implements image processing algorithms for real-time distance measurement is presented. Using embedded development kit (EDK) tools from Xilinx, the system is developed on a spartan3 / xc3s400, one of the common and low cost field programmable gate arrays from the Xilinx Spartan fami...

Virtual Reality simulators of heavy machinery are often used for training purposes. However, the complexity of terrain as a dynamical system makes the simulation of earthmoving machinery an specially challenging problem. In this paper, the architecture of an excavator simulator is described, together with the different models used to describe the behavior of the systems involved. Special attent...

This work describes the development and the application of a computer-based vehicle simulator. Such real-time simulation software is currently used in our Department as a tool for optimizing the design of a racing car, namely a single-seat vehicle for the SAE-ATA formula. Being based on our custom multibody library Chrono::Engine, the vehicle simulator exploits a recent formulation founded on v...

This paper presents a review of current research in the area of real-time crowd simulation. Crowd simulation has many diverse uses, for example in safety modelling, entertainment software, architecture and urban modelling applications. We describe three main approaches to the problem fluid-based, cellular automata and particle-based, concentrating on the latter. Finally, we describe CrowdSim, a...

Based on a discrete-event simulation model, Simulationbased Real-time Decision-Making (SRDM) is an innovative approach to real-time, goal-directed decision-making. When applied to a flexible manufacturing system, SRDM makes better decisions than most fixed policies, such as deterministic, stochastic and manual. SRDM even improved over fixed policies optimized within a class of policies by OptQu...

This article studies the usefulness of parallel processing in real-time traffic-flow simulation based on continuum modeling of traffic dynamics. Computational fluid dynamics (CFD’s) methods for solving simple macroscopic traffic-flow continuum models have been studied and efficiently implemented in traffic simulation codes (on serial computers) in the past. We designed a traffic-flow simulation...

We introduce precomputed multizone elastokinematic models for interactive simulation of multibody kinematic systems which include elastostatic deformations. This enables an efficient form of domain decomposition, suitable for interactive simulation of stiff flexible structures for real time applications such as interactive assembly. One advantage of multizone models is that each zone can have s...

Despite tremendous work in hair simulation a unified framework for creating realistically simulated hairstyles at interactive rates is yet not available; the main reason is that complex dynamic and optical behavior of hair are computationally expensive to simulate. To have such a framework, it is essential to find optimized solutions, especially for the various physics-based tasks, which is the...
