Real-Time Fluid Simulation and Visualization / Simulering och visualisering av vätskor i realtidWolmerud, Markus January 2015 (has links)
This thesis presents a method based on Smoothed Particle Hydrodynamics to simulate sparse particle systems with fluid like properties in real-time. The simulation supports interactions with terrain and objects and is scaled depending on activity of the fluid. We use a carpet method on the GPU to visualize the water surface with translucency, reflection, refraction and added topology. Splash effects and foam are imitated and added as a last step.

A Graph-Based Approach to Procedural TerrainMijailovic, Vidak January 2015 (has links)
Procedural terrain generation is a field that handles procedural, not by hand, generated realistic looking terrain for use in simulations, video games, movie special effects or art. It allows for creation of vast and far more detailed terrain than humans can create by hand. In this paper a new method for procedural terrain generation is presented. Terrain is generated in three steps. An arbitrarily shaped network oh nodes, a graph, is used as a base to design the shape and layout of terrain features. Common algorithms are used to generate custom terrain features inside the graphs sealed areas and finally the generated terrain is merged into a single piece using a new method. In this manner, more controlled and detailed terrain can be created as the layout and shape of features can be controlled. / Området terräng generering hanterar procedurellt, icke för hand, skapande utav realistisk terräng för användning inom simulationer, data spel, filmers specialeffekter och konst. I denna uppsats presenteras en ny metod för procedurell terräng generation. Terrängen genereras i tre steg. Ett godtyckligt nätverk av noder skapas, en graf, och används som grund för att designa och forma utläggningen av terrängens drag. Kända algoritmer används för att skapa dragen inuti grafens tomma ytor och slutgiltigen sys den genererade terrängen ihop till en sammanhängande helhet med en ny metod. På detta vis kan man skapa mera detaljerad och bättre styrd terräng då man både kan kontrollera dragens former och utläggning.
