Real-time simulation of water surface
نویسنده
چکیده
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 embraces a number of techniques covering all three steps of water simulation: the surface generation, optical effects imitation and building a polygon mesh. Some of the used techniques are well known; we have adapted them to real time requirements. Some new algorithms were developed. There are presented results of implementation of these three steps altogether: on up-to-date personal computers we can calculate and render the surface 30 times per sec and spend at most 8 ms for each frame.

Effects of Surface Modification on the Recovery Time and Stability of Nanostructured Tin Oxide Thick Films Gas Sensors
Along with high sensitivity in detecting gas, the response and recovery times of semiconductor gas sensors are of considerable importance for real life applications. In most cases, the recovery time is more than the response time. At the same time, water vapor present in the ambient, is chemisorbed on the tin oxide, SnO2 surface and the water molecules dissociate into hydroxyl species, which ac...

Wall-jet flow is an important flow field in hydraulic engineering, and its applications include flow from the bottom outlet of dams and sluice gates. In this paper, the plane turbulent wall jet in shallow tailwater is simulated by solving the Reynolds Averaged Navier-Stokes equations using the standard turbulence closure model. This study aims to explore the ability of a time splitting method ...

متن کاملReal-Time Erosion Using Shallow Water Simulation
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...
