<div>In this thesis, we investigate methods for texture synthesis and texture re-rendering of indoor room scene images. The goal is to create a photorealistic redesign of interior spaces by replacing surface finishes with a new product based on a single room scene image. Specically, we focus on automating this process to reduce manual input while enabling high-quality and easy-to-use experience. The most common method of rendering textures into a scene is called texture mapping. Texture mapping involves mapping pixels in a texture sample to vertices in an object model. Typically, a large texture sample is required to perform texture mapping properly. Given a small texture sample, texture synthesis creates a large sized texture that appears to have</div><div>been made by the same underlying process. In the first part of this thesis, we present a method of texture synthesis that automatically determines a set of parameters to produce satisfactory results based on the texture types. The next challenge is to create a photorealistic re-rendering of the synthesized texture in the room scene image. 3D scene information such as geometry, lighting and reflectance is crucial to making the re-rendered image realistic. These properties contribute to the image formation process and must be estimated to create a scene-consistent modication. Knowing these parameters allows effects like highlights, shadows and inter-object reflections to be maintained during the re-rendering process. We detail methods for estimating</div><div>these parameters from a single indoor image. Finally, we will show a web-based implementation of these methods using the WebGL library ThreeJS.</div>

Given mobile devices’ weak computational power, game programmers must learn to create games with simple graphics that are engaging and easy to play. Though seldom created for phones and tablets, puzzle games are a perfect fit. In recent years, the genre has gained a following and even won some acclaim. Games like Myst, The Seventh Guest and Portal all engage gamers with challenging puzzles and then reward them with story components upon task fulfillment. Few such games have been created for mobile devices, in part due to the difficulty of developing for devices with different operating systems. Android, WebIOS and Windows Phone all have different software development kits that produce a final product incompatible with operating systems other than what it was developed for. One promising solution is to use browser technology to deliver games since all devices are geared to interact with the Web through browsers such as Internet Explorer, Mozilla Firefox, and Google Chrome. The aim of this project was to build a puzzle game that can be run on any digital device. The project can be accessed without any plug-ins and was created by using web technologies such as JQuery, Touch Punch, local storage, and WebGL. JQuery allows drag and drop functionality and Touch Punch allows the JQuery functionality intended for a mouse to work on a touch interface. Local storage provides storage on a user’s device, as opposed to a server, and WebGL enables graphics processing on a user’s tablet or phone through web commands.

En stor kvantitet av miljödata samlas hela tiden in och för att dra nytta av all data behöver den förstås av de användarna som kan applicera kunskapen inom deras område. Visualiseringar tillåter användare att förstå datan och det är därför en viktig del av hur en användare kan ta del av den datan som samlas in. I detta arbete evalueras de WebGLbaserade teknologierna Three.js och X3DOM om vilken som är mest lämplig för att visualisera geospatial data på webben utifrån hur effektiva de är vid rendering av heatmaps. Två applikationer utvecklas, en baserat på Three.js och en på X3DOM. Mätningar utförs på varje applikation för att jämföra renderingstiden mellan teknologierna och en kvalitativ studie används för att evaluera deras användbarhet. Resultatet blev att Three.js är mer lämpligt för att visualisera geospatial data på webben.

The regular way of displaying maps in a web browser is by downloading raster images from a server and lay them side by side to make up a map. If any information on the map is changed, new images has to be downloaded, it cannot be done on the client. The introduction of WebGL opens up a whole new world of delivering advanced graphics content to the end user in a web browser. Utilizing this technology for displaying maps means only the source data is sent to the web browser where the map gets rendered using the device's GPU. This adds a number of benefits such as the ability of changing map appearance on the client, add new features to the map and often less data transfer. It however sets higher expectations of the client device's hardware as it needs to render the map at a high enough frame rate to not appear slow and unresponsive. This thesis investigates a framework for client side map rendering in a web browser, Mapbox GL JS, with focus on performance. It shows how map source data can be generated as well as its corresponding style rules are constructed with performance in mind. It provides benchmarking results of different map data sets with different detail intensity and shows that a device with good GPU performance is needed for an acceptable user experience. It also shows that lowering the amount of rendered detail does not necessarily result in better performance.

Movement-based games are becoming more frequent in everyday lives. With easier access to webcams built into laptops and web-based games, a game which utilises both concepts can become a good option for everyday gaming.This study evaluates a movement-based game written in JavaScript using phaser.io which uses a webcam for control and HTML5 technique for capture. The main questions in the study are what observations can be done and are there any problems when developing a game with webcam-based motion-detection in regards to factors like flow, feedback and positioning. This study tries to answer these questions by building upon an existing game and implementing new functions and feedback and then observing how these effect the game-play. The results of the study showed that it is important to consider good feedback and how to position oneself when playing such a game and that more testing should be done to gain further knowledge about these two. But also that many of the implementations done made the person achieve flow while playing. Further work should be beneficial also to make the game even better while keeping it easy to play.
