The Seven Valleys is an interactive 3D installation based artwork inspired by mystical writings of the Bahá'í Faith. Created as a modification of the firstperson shooter Unreal Tournament 2003 (Epic, 2003) it subverts the original paradigm of the game to create an experience of the numinous, which in spirit, is diametrically opposed to the original intent of the gameplay design. This artwork presents an exploration of, and allusion to, the often subtle and illusive concepts found in the sacred treatise The Seven Valleys (Bahá'u'lláh, 1991) in which the user engages in an experiential journey through the work. The user is faced with conditions and situations that provide motivation to question, explore and attempt to fathom the abstract sense of the numinous. Each of The Seven Valleys contains its own individual mysteries while at the same time contributing its part to the telling of a collective story. / Master of Arts

Hur människor uppfattar rumsligheter är komplext. Människor baserar det upplevda rummet på professionell expertis, erfarenheter och vilket visuellt kommunikationsverktyg som rummet presenteras med hjälp av. Studiens syfte är att undersöka hur den visuella kommunikationen mellan arkitekter och kunder ser ut, hur arkitekter och kunder uppfattar rumsligheter, hur uppfattningen skiljer sig åt och om kommunikationen däremellan kan underlättas med hjälp av realtidsvisualisering (VR). Dessutom undersöker examensarbetet hur en sådan visuell kommunikation skulle kunna gå till och hur detaljerad en VR-modell behöver vara. Spelmotorn Unity och VR-plattformen HTC Vive används för att producera och driva interaktiva VR-modeller. Studien undersöker hur dessa kan användas som ett visuellt kommunikationsverktyg mellan arkitekter och kunder för att utveckla kommunikationen dem emellan. Litteraturen visar på tydlig klyfta i kommunikationen mellan arkitekt och kund där information går förlorad. Genom användandet av realtidsvisualisering hävdas det att kommunikationen kan underlättas och en ökad förståelse av rymd och skala uppnås. I studien testas tre VR-modeller med tre olika detaljnivåer på respondenter, tre arkitekter och två kunder. Efter testet intervjuas personerna om deras erfarenheter och rumsliga upplevelse för de olika modellerna. Intervjuerna pekar på att den skillnad i rumsuppfattning som finns mellan arkitekt och kund kan överbryggas med hjälp av VR som kan konkretisera arkitektur och medför att alla kan förstå rumsligheter på sina egna villkor. Undersökningen visar att VR är ett användbart visuellt kommunikationsverktyg. Inte bara som barriärbrytande mellan arkitekt och kund utan även som en integrerad del av den iterativa designprocessen. / How people perceive space is a complex thing. People base the perceived space on professional expertise, experiences and what visual communication tools the room is presented with. The purpose of the study is to investigate the visual communication between architects and clients; how architects and clients perceive spatial characteristics and how the perception differs and whether communication between them can be made easier using real-time visualization (VR). In addition, the study investigates how such communication could go and how detailed a VR model needs to be. The game engine Unity and VR-platform HTC Vive are used to produce interactive VR models and investigate how these can be used as a visual communication tool between architects and clients to improve the communication between them. The literature shows a clear gap in the communication between architects and clients where information is lost. Using real-time visualization, the communication can be eased, and an increased understanding of space and scale achieved. In the study, three VR models are tested with three various levels of detail on respondents, three architects and two customers. After the test, the respondents are interviewed about their experiences and space perception of the different models. The interviews show that the difference in space perception between architect and client can be overcome using VR that can show architecture and allow everyone to understand spatiality on their own terms. The investigation shows that VR as a visual communication tool is useful. Not only as barrier-breaking between architects and clients, but also as an integral part of the iterative design process.

The goal of the thesis is to create an extension for Unity Development Platform that will allow creation of computer games from design of game logic to scene programming on visual level. The extension forms an abstract layer between designers, who manage game objects on logic level, and programmers, who are responsible for implementation of parts that can't be created automatically. It then facilitates some designing processes and iterations by eliminating the need of manual programming in places that can by automate and allows to concentrate on the design process itself.

This work deals with driving skills training problematics using a driving school 3D simulator, which monitors the observance of road traffic rules. Existing simulators are categorized by characteristics and described. The text contains a list of implemented rules and a summary of suitable tools. The resultant application is based on the Unreal engine and the text describes the various stages of development.

In 2019, the Covid-19 pandemic struck the world, creating a need for social distancing to stop the spreading of the virus. This report will discuss and cover how a simulation was implemented in the game engine Unity that simulates human movement-patterns, which in turn will help with spreading people out in public areas. To be able to do this accurately, research was made about which behaviours can be of importance to get as realistic a representation of human movements as possible. The performed research showed that some contributing factors to get a realistic result includes how many destinations (e.g. in a Supermarket, a destination would be a shelf with wares) a human usually visits during a shopping trip to a supermarket. This is something that was quickly realized and could be used and implemented in the simulation, as it directly affects how long each human stays in the store, which in the long run makes crowds, and places where they form, more realistic. When the simulation was finished, a Google Forms was created, which were spread in numerous different groups on Facebook and Reddit, in which a total of 60 participants were registered. This quantitative research gave a good understanding of how the project had turned out and what could be improved. The results were very promising, and more or less what was hoped for. There is still room for further improvements, which are all mentioned in the chapter “Further Research” of this report. One example that is mentioned here is whether or not collisions between our simulated humans matter enough to make a difference to the end result. It is argued that it does not, but this is something one should perform further studies on.

This thesis investigates whether a game world based solely on fluid dynamics could be an interesting alternative to one based on rigid bodies by presenting a prototype to players where they can control the movement of a fluid. The players evaluate the prototype’s responsiveness, intuitiveness, visual appeal, immersion, and how well they think the fluid could represent ghosts, flocks, magic, and a platformer avatar by rating them vocally while playing. The fluid physics engine prototype is a simple grid-based one that utilizes the ideal gas law and pressure gradient force to calculate the flow between its cells. It is unstable and thus cannot handle too large time-steps. Therefore, simulating many cells (more than 10000 for two fluids) at the same is a slow process, and the prototype can only present a pixelated result. If a highresolution game is in general preferred by players, a computationally efficient solution could consist of utilizing shaders for cell blending. In the experiments, all categories except the platform avatar received positive evaluations despite the prototype’s early stage, which according to theories presented within Swink’s Game Feel (Swink, 2009) and the MDA framework (Hunicke et al., 2004) may indicate that a game based on a fluid physics engine like this one could be entertaining. The simulation could possibly be run as a separate system to add game mechanics to a game based on rigid bodies as well.

In this thesis we propose a navigation instruction validation tool and an user training tool for PERCEPT system. The validation tool evaluates the navigation instructions using a virtual reality environment by ensuring that each path in the virtual environment can be traversed by following the navigation instructions. This validation tool will serve as a first automatic validation of navigation instructions prior to testing them with blind and visually impaired users. The user-training tool enables the blind user to explore and get familiar with the real environment by using the virtual environment generated in the Unity3d based game. The user interacts with the game using PERCEPT Smartphone client just like the user would interact in the real environment. Motion in the game is emulated using the keyboard. Motion directions follow the navigation instructions obtained through the Smartphone. This user-training tool will improve the users experience in the real environment by enabling them to explore and learn the environment a-priori to their arrival in the physical space.

This paper investigates alternative scheduling for game objects in a game engine by using priority based algorithms and comparing different priority assigning methods. Research concerning commercial game engines, game loops, concurrency and scheduling was performed. Three different scheduling algorithms were created and tested using a varying amount of game objects between two different testing scenarios. The results showed that using priority based scheduling gave a slight increase in average frames  per second (FPS) as well as boosting logical update performance of prioritized objects, however overall performance was decreased. The reason this decrease in performance occurred could have been due to the way the scheduler was implemented, and despite the decrease in performance using a priority based scheduling system was considered feasible within certain game engines. / Denna uppsats undersöker alternativa sätt för schemaläggning av spelobjekt i en spelmotor genom att använda prioriteringsbaserade algoritmer och jämföra olika tilldelningssätt för prioritetsmetoder. Forskning gällande kommersiella spelmotorer, ''game loops'', parallellisering och schemaläggning utfördes. Tre olika schemaläggningsalgoritmer skapades och testades med ett varierande antal spelobjekt i två olika testscenarion. Resultaten visade att användning av prioritetsbaserad schemaläggning gav en lätt ökning av det genomsnittliga antalet bilder per sekund (FPS) och gav bättre logikuppdateringsprestanda för prioriterade objekt. Den totala prestandan minskade dock. Anledningen till att denna minskning i prestanda skedde kan bero på hur schemaläggaren implementerades, men trots denna prestandaminskning ansågs schemaläggningssystemet vara möjlig inom vissa spelmotorer.
