Abstract [en]

In this master thesis report a new method for simulating waters surface waves is presented. The method is well adapted for real-time applica- tions and has been developed with computer games in mind. By sim- ulating the water surface at several different resolutions simultaneously using a construction similar to Laplacian Pyramids dispersion is handled approximately resulting in a complex behaviour.

The simulation is also extended with a dynamic level of detail method and phenomenological models for boundaries and high frequency waves. This method is pro- totyped inside the Frostbite™ engine developed at EA™ DICE™ and runs at 3 ms per time step on a single core of a Intel™ Xeon™ processor with high quality results.

Abstract [sv]

Denna rapport presenterar resultaten för ett examensarbete om simu- lering av vattenvågor. En ny metod för att simulera vattenvågor pre- senteras. Denna metod är anpassad för realtids-tillämpningar och har utvecklats med datorspel i åtanke. Genom att simulera en vattenyta med flera upplösningar samtidigt i en pyramidstruktur hanteras dispersion approximativt.

Simuleringen varierar dynamiskt upplösning beroende på avstånd till observatören och för att öka detaljnivån finns ett feno- menologiskt detaljsystem. En prototyp har utvecklats inuti spelmotorn Frostbite™som utvecklats av EA™ DICE™. Prototypen simulerar ett steg på 3 ms men en kärna hos en Intel™ Xenon™-processor med bra resultat.
