The paper is devoted to efficient algorithms for computer simulation of water surface with waves. The water surface is a usual component of virtual environment in trainers/simulators and games and often should look as highly realistic as possible, which leads to sophisticated algorithms. On the other hand, these algorithms are aimed at real time mode, and their high speed is crucial. This paper...

This paper presents a framework for the modeling and simulation of the dynamics of complex deformable space systems. It is based on a suite of free software, mostly developed and distributed by the ‘Dipartimento di Ingegneria Aerospaziale’ of Politecnico di Milano (DIA-PM), that allows the real-time simulation of arbitrarily complex mechanical, mechatronic and aeroservoelastic systems. Real-tim...

While physics-based modeling of electrosurgical procedures is essential for most laparoscopic simulation systems, we present such a system for the first time in this paper. We have implemented a physics-based model of electrosurgery to control the temperature distribution on the tissue as a function of time. Then, we evaluate the algorithm within a complete graphics-haptics-physics-based system.

This paper describes typical modeling and realtime simulation issues that occur in automotive applications. Real-time simulations of detailed Modelica benchmark models for chassis and powertrain are presented. They demonstrate the powerful real-time capabilities of Dymola and the Modelica modeling language. One of the benchmark models for vehicle dynamics is a detailed model with 72 degrees-of-...

Existing work on applications for thin watery paint is mostly focused on automatic generation of painterly-style images from input images, ignoring the fact that painting is a process that intuitively should be interactive. Efforts to create real-time interactive systems are limited to a single paint medium and results often suffer from a trade-off between realtimeness and simulation complexity...

In this paper we describe an approach to interactively render ultrasound images for a transesophageal echocardiogram procedure. Our prototype features an animated 3D model of a human heart that is used to synthesize virtual ultrasound images in real-time. The user can control the probe and interact with the simulator via a GUI or with a haptics device. The ultrasound plane is rendered in a clas...

This paper presents a real-time simulation method for coupling of cloth and fluids computed by using Smoothed Particle Hydrodynamics (SPH). To compute interaction between cloth consisting of several polygons and fluid particles, the distance between cloth to the particle have to be calculated. It is computationally expensive because we have to compute the distance to the faces, edges and vertic...

Music visualization has always attracted interest from people and it became more popular in the recent years after PCs and MP3 songs emerged as an alternative to existing audio systems. Most of the PC-based music visualization tools employ visual effects such as bars, waves and particle animations. In this work we define a new music visualization scheme that aims to create life-like interactive...

This paper shows a tool chain of a set of ready-touse tools and libraries that enables the dynamic real-time simulation of vapour compression cycles. A new approach for calculation of fluid properties and numeric efficient component models are applied. As an Hardware in the Loop application a vapour compression cycle is exported to Scale -RT [5] using SimulationX [11] and connected to a hardwar...
