Stohastic Generator for a Real-Time Wind Simulation

Abstract

In nature, wind is considered to be a stochastic attribute of weather, whose momentary speed and direction are easily measureable, but extremely hard or nearly impossible to predict. Wind simulation is used in many fields of computer processing and modeling. Our stochastic generator is primary designed for use in wind modeling in the simulations of irrigation processes. In real world there is an event, rather a movement that is generally considered to be unable to predict - a flight of a real object. In real conditions, every object thrown in any direction, other than straight down, moves along a ballistic curve. Our method is based on simulating the flight of high number of objects and collisions between them. Collisions are implemented for two main reasons - to move objects in a bounded finite space when collisions with borders are implemented, and to change the objects' directions at a time of a collision to make objects to stay in space.

U prirodi se vetar smatra stohastičkim atributom vremena, čiji se trenutni brzina i smer mogu lako izmeriti, ali ih je veoma teško ili gotovo nemoguće predvideti. Simulacija vetra se koristi u mnogim oblastima računarske obrade i modeliranja. Naš stohastički generator je primarno konstruisan za upotrebu u modeliranju vetra u simulacijama postupaka navodnjavanja. U stvarnom svetu postoji jedan događaj, ili bolje pokret koji smatra da je nemoguće predviđanje leta realnog objekta. U stvarnim uslovima, svaki predmet bačen u bilo kom smeru, izuzev pravo dole, kreće se po balističkoj krivoj. Naš metod se zasniva na simulaciji leta velikog broja objekata i njihovih međusobnih sudara. Sudari su uvršteni iz dva glavna razloga – da pomeraju objekte u ograničenom konačnom prostoru kada su uvršteni sudari sa granicama, i da menjaju smerove objekata u vreme sudara da bi objekti ostali u prostoru.
