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.

[ES] La quinta generación de comunicaciones móviles, 5G, promete ser una revolución tecnológica que vaya más allá de multiplicar la velocidad de transmisión de datos de sus predecesoras. Pretende soportar una gran cantidad de dispositivos y alcanzar latencias muy cercanas a 1 milisegundo. Para satisfacer estos ambiciosos requisitos, se han investigado nuevas tecnologías habilitadoras. Una de ellas es el uso de las bandas de ondas milimétricas (mmW) en las cuales hay una gran cantidad de espectro disponible. Para predecir las características del canal radio y evaluar las prestaciones de la 5G de forma fiable en las bandas mmW se requieren modelos de canal complejos. Concretamente, los modelos de propagación más precisos son los basados en trazado de rayos, pero su alto costo computacional los hacen inviables para la caracterización del canal radio en escenarios complejos. Por otro lado, en los últimos años, la tecnología de videojuegos ha desarrollado potentes herramientas para modelar la propagación de la luz en escenarios superrealistas. Dada la cercanía espectral entre el espectro visible y las ondas mmW, la presente Tesis ha estudiado la aplicación de las herramientas de modelado de propagación de la luz de los motores de juego para el modelado del canal radio en mmW. Esta Tesis propone un modelo de estimación de las pérdidas de propagación en mmW llamado "Modelo de Intensidad de Luz'' (LIM). Usando este modelo, basado en los procesos de iluminación realizados por los motores de juego, los transmisores de señal se sustituyen por focos de luz y la intensidad lumínica recibida en un punto se traduce a potencia de señal en milimétricas a través de una función polinómica sencilla. Una de las ventajas de usar los motores de juego es su gran capacidad y la facilidad que tiene el usuario para crear escenarios superrealistas que representen fielmente la geometría de escenarios donde se quiera evaluar el canal radio. De esta forma se pueden obtener estimaciones precisas de las pérdidas de propagación. La estimación de las pérdidas de propagación con LIM ha sido comparada con campañas de medida en las bandas de 28 GHz y 73 GHz y con otros modelos de propagación. Como resultado, el error de estimación de LIM es menor que los modelos estocásticos actuales y es comparable con el modelo de trazado de rayos. Y, además, el coste computacional de LIM comparado con el trazado de rayos es 130 veces menor, lo que posibilita el uso de LIM en escenarios altamente complejos para la estimación del canal radio en tiempo real. Los motores de juego permiten caracterizar de forma diferente la interacción de los materiales con la luz configurando el mapa de normales de sus superficies y sus funciones de dispersión y reflexión. En esta Tesis se ha determinado la caracterización de varios materiales que mejor se ajusta a medidas de laboratorio realizadas en un escenario controlado en la banda de 28 GHz. El modelo de LIM empleando materiales con esta caracterización óptima reduce más de un 50\% su error de estimación con respecto a la aplicación de LIM con los materiales por defecto, mientras que su coste computacional sigue siendo 26 veces menor que el modelo de trazado de rayos. Finalmente, se ha desarrollado sobre un motor de juego una primera versión de plataforma para la emulación de los sistemas 5G que es el punto de partida para un emulador completo de 5G. Esta plataforma no sólo contiene el modelo de LIM sino que incluye varios casos de uso de la 5G en entornos superrealistas. La plataforma, que se basa en el concepto de "Serious Game Engineering", rompe las limitaciones de los simuladores de redes móviles en cuanto a las capacidades de visualización e interacción del usuario con los componentes de la red en tiempo real. / [CAT] La cinquena generació de comunicacions mòbils, 5G, promet ser una revolució tecnològica que vaja més enllà de multiplicar la velocitat de transmissió de dades de les seues predecessores. Pretén suportar una gran quantitat de dispositius i aconseguir latències molt pròximes a 1 mil·lisegon. Per a satisfer aquests ambiciosos requisits, s'han investigat noves tecnologies habilitadores. Una d'elles és l'ús de les bandes d'ones mil·limètriques (mmW) en les quals hi ha una gran quantitat d'espectre disponible.

Una dels avantatges d'usar els motors de joc és la seua gran capacitat i la facilitat que té l'usuari per a crear escenaris superrealistes que representen fidelment la geometria d'escenaris on es vulga avaluar el canal ràdio. D'aquesta forma es poden obtindre estimacions precises de les pèrdues de propagació. L'estimació de les pèrdues de propagació amb LIM ha sigut comparada amb campanyes de mesura en les bandes de 28~GHz i 73~GHz i amb altres models de propagació. Com a resultat, l'error d'estimació de LIM és menor que els models estocàstics actuals i és comparable amb el model de traçat de rajos. I, a més, el cost computacional de LIM comparat amb el traçat de rajos és 130 vegades menor, la qual cosa possibilita l'ús de LIM en escenaris altament complexos per a l'estimació del canal ràdio en temps real. Els motors de joc permeten caracteritzar de forma diferent la interacció dels materials amb la llum configurant el mapa de normals de les seues superfícies i les seues funcions de dispersió i reflexió. En aquesta Tesi s'ha determinat la caracterització de diversos materials que s'ajusta millor a mesures de laboratori realitzades en un escenari controlat en la banda de 28 GHz. El model de LIM emprant materials amb aquesta caracterització òptima redueix més d'un 50 % el seu error d'estimació respecte a l'aplicació de LIM amb els materials per defecte, mentre que el seu cost computacional continua sent 26 vegades menor que el model de traçat de rajos. Finalment, s'ha desenvolupat sobre un motor de joc una primera versió de plataforma per a l'emulació dels sistemes 5G que és el punt de partida per a un emulador complet de 5G. Aquesta plataforma no solament conté el model de LIM sinó que inclou diversos casos d'ús de la 5G en entorns superrealistes. La plataforma, que es basa en el concepte de "Serious Game Engineering", trenca les limitacions dels simuladors de xarxes mòbils quant a les capacitats de visualització i interacció de l'usuari amb els components de la xarxa en temps real. / [EN] The fifth generation of mobile communications, 5G, promises to be a technological revolution that goes beyond multiplying the data transmission speed of its predecessors. It aims to support a large number of devices and reach latencies very close to 1 millisecond. To meet these ambitious requirements, new enabling technologies have been researched. One of these is the use of millimetre-wave bands (mmW) in which a large amount of spectrum is available. Complex channel models are required to predict radio channel characteristics and reliably evaluate 5G performance in the mmW bands. Specifically, the most accurate propagation models are those based on ray tracing, but their high computational cost makes them unfeasible for radio channel characterization in complex scenarios. On the other hand, in recent years, video game technology has developed powerful tools to model the propagation of light in super realistic scenarios. Given the spectral closeness between the visible spectrum and the mmW waves, the present Thesis has studied the application of light propagation modeling tools from game engines for radio channel modeling in mmW. This Thesis proposes a model for estimating propagation losses in mmW called "Light Intensity Model'' (LIM). Using this model, based on the lighting processes performed by the game engines, the signal transmitters are replaced by light sources and the light intensity received at a point is translated into signal strength in mmW through a simple polynomial function. One of the advantages of using the game engines is their great capacity and the ease with which the user can create super realistic scenarios that faithfully represent the geometry of scenarios where the radio channel is to be evaluated. In this way, accurate estimates of propagation losses can be obtained. The estimation of propagation losses with LIM has been compared with measurement campaigns in the 28 GHz and 73 GHz bands and with other propagation models. As a result, the LIM estimation error is smaller than the current stochastic models and is comparable with the ray tracing model. In addition, the computational cost of LIM compared to ray tracing is 130 times lower, allowing the use of LIM in highly complex scenarios for real-time radio channel estimation. The game engines allow to characterize in a different way the interaction of the materials with the light configuring the normal map of their surfaces and their scattering and reflection functions. In this Thesis it has been determined the characterization of several materials that best fits to laboratory measurements made in a controlled scenario in the 28 GHz band. The LIM model using materials with this optimal characterization reduces by more than 50% its estimation error with respect to the application of LIM with default materials, while its computational cost remains 26 times lower than the ray tracing model. Finally, a first version of a platform for the emulation of 5G systems has been developed on a game engine, which is the starting point for a complete 5G emulator. This platform not only contains the LIM model but also includes several 5G use cases in super realistic environments. The platform, which is based on the concept of "`Serious Game Engineering", breaks the limitations of mobile network simulators in terms of visualization capabilities and user interaction with network components in real time. / Inca Sánchez, SA.

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.
