Abstract [en]

Background: Snow simulation can be used to increase the visual experience in applicationssuch as games. Previously, snow has been simulated in real-time through two-dimensional gridbased methods, which limits itself in the aspect of dynamic interactions. To widen the scope ofwhat games current game engines can produce, an approach to simulating the behavior of snowwith non-recoverable compression and phase transition is proposed.

Objective: The objective of this thesis is to construct a particle simulation model to simulate thebehaviors of snow in regards to compression and phase transition in real-time. The solution islimited to the behavior of deposited snow, and will therefore not consider the aspect of snowfalland realistic visualization.

Method: The method consists of a particle simulation with incorporated functionality ofcompression and thermodynamics. Test cases based on compression, phase transition andperformance have been conducted.

Results and Conclusions: The results show that the model captures phase transition with thephases of snow, ice, and water. Compression by external forces and self-weight is also captured,but with missing behavior in terms of bond creation between grains. Performance measurementsindicates that the simulation is applicable for real-time applications. It is concluded that theapproach is a good stepping stone for future improvements of snow simulation.

Abstract [sv]

Bakgrund: Snösimulering kan användas för att öka den visuella upplevelsen i applikationersåsom spel. Tidigare har simulering i realtid gjorts genom tvådimensionella rutnätsmetoder,vilka begränsar den dynamiska interaktionsaspekten. För att bredda omfattningen av vilka spelaktuella spelmotorer kan producera föreslås en metod för att simulera beteendet av snö medicke-återhämtande kompression och fasövergång.

Syfte: Syftet med denna avhandling är att konstruera en partikel-simuleringsmodell för attsimulera beteendet av snö i förhållande till kompression och fasövergång i realtid. Lösningen ärbegränsad till ackumulerad snö, och tar därmed inte upp snöfallaspeketen och realistiskvisualisering.

Metod: Metoden består av en partikel-simuleringsmetod med inbyggd funktionalitet avkompression och termodynamik. Testfall baserade på kompression, fasövergång och prestandahar utförts.

Resultat och Slutsatser: Resultaten visar att fasövergång fångas av modellen med faser av snö,is och vatten. Kompression av självvikt samt externa krafter har också fångats, dock med saknatbeteende av bandskapande mellan snökorn. Prestandamätningar indikerar att simuleringen ärlämplig för realtidsapplikationer. Slutsatsen är att tillvägagångssättet är ett steg i rätt riktninginför framtida implementationer av snösimulering.
