Today a lot of libraries, tools and techniques exist to create visual appealing renders for the web. In this thesis, a prototype for visualizing baseboards in the web browser was developed. The prototype demonstrates how certain libraries and techniques were used in order to achieve a generalized, appealing and realistic visualization of the baseboards in a 3D-visualization. This paper also covers why certain libraries and techniques were used for this prototype. The resulting prototype, use Three.js and takes advantage of PBR, different mapping methods and lighting sources that can be changed during runtime through a GUI. To get results on different aspects, such as the visual appeal, how realistic, and what lighting sources worked best for the prototype, a web-survey was sent out and the results evaluated. The evaluation showed that the usage of PBR, a roughness-metalness workflow, environment mapping, physical correct lighting and a point light solution in Three.js all made a good job in creating an appealing, generalized and realistic visualization tool for the web.

With age, more light is needed in order to function, but the effect of lighting on occupational performance has received little attention in occupational therapy. The purpose of the study was to determine if lighting affects older adults’ ability to perform selected occupational tasks, which require near vision and if lighting levels affects their perceived effort while performing selected occupational tasks. A quasi-experimental, repeated measures design was used with a convenience sample recruited from a retirement community. Thirty participants met the inclusion criteria, which included visual and cognitive screening. The mean age of the 30 participants was 83 years, and most (80%) were female. Participants completed three occupational tasks (reading a prescription label, sorting pills, and sorting dark colored socks) under three different lighting levels (low, M = 103; medium, M = 127; and high, M = 397 footcandles [fc]) presented in random order. Participants were placed in three groups based on order of lighting presentation and completed each set of tasks four times: a trial session, followed by three timed sessions. Participants were asked to rate their perceived effort under each lighting level using a self-report scale. Descriptive statistics were used to examine completion times, groups, and lighting levels. In general, participants required longer to complete occupational tasks and reported more effort when utilizing medium light levels (M = 127 fc) provided by ambient lighting and a floor lamp and performed best under high lighting levels (M = 397 fc) provided by ambient lighting as well as a floor lamp and task lamp. The results suggest lighting may have affected performance and perceived effort of older adults while completing the visually challenging tasks.

As we move forward in time, our cities are meant to be progressive, which should ideally prioritize its pedestrians and make spaces inclusive to all socio-economic groups. On the contrary, observation tells that some of our cities get designed with an “orthodox” approach by keeping in mind the interests of motorways with high mast blue-rich LED luminaires. Such a system does not allow pedestrian-oriented activities, such as Farmer’s markets, Food Streets, Public Plazas, etc., to thrive and leaves smaller streets where such activities happen in darkness or with unplanned, quick fix lighting.While darkness is good for the environmental benefit of light pollution, certain parts of our cities need to be lit the right way for the apt functioning of the urban realm.Based on the placemaking concept by urban activists/journalists and sociologists such as Jane Jacobs and William H Whyte there are 4 attributes to making a place great. The place diagram represents the four attributes: access and linkages, comfort and image, uses and activities, and scalability. The study utilizes the Place Diagram as a basis for the analysis and design of the lighting of the Russell Market Promenade site in Bangalore.The design proposal will focus on the various user groups of the space and the creative pattern of space use. The assessment of the lighting proposal is by the users of the space, architects, lighting designers, and pedestrians in the area.

The rise of rock climbing is a global phenomenon. Seven out of ten bouldering gyms opened during this decade in Stockholm. With the increasing sports climbing population, the lighting condition of sports facilities should be a concern, especially since electricity demand growth in buildings has been remarkably rapid. However, not much research has been conducted regarding investigating the effect of artificial lighting on indoor bouldering users' experiences. This thesis investigates a balance between addressing sustainable development goals number 7.3 and maintaining users' experiences while exercising, taking Klätterverket Gasverket as a case study. Different research methods have been used to provide a pilot study to be explored by others, including literature review, semi-structured interviews, and empirical study.  This research has shown that it is hard to draw conclusions regarding the perceived qualities of light. The qualitative and quantitative results conclude that we can decrease electrical consumption in a situation that has sufficient daylight without sacrificing climbers’ experience.  Adjusting the distance between the luminaire and climbing wall can slightly improve the average illuminance level and user experience.

This thesis will cover the entirety of the development process of Skara Skyddsängels virtual reality test platform. The platform means to support their efforts in creating a lighting drone service that assists pedestrians and cyclists in areas lacking proper lighting infrastructure while at the same time promoting sustainable modes of transportation. Unreal Engine 4 was used since it provides all the tools needed in order to create the desired product. All changeable parameters requested by the supervisor are fully implemented, such as drone altitude, light angle, and light intensity. Beyond the required parameters, some additional miscellaneous features, such as ambient sound, are also implemented to increase the immersion further. The result is a functioning test platform with an environment resembling a rural road in Skara that can assist the Skara Skyddsängel project in accelerating its testing. / Denna kandidatrapport handlar om den kompletta utvecklingsprocessen för Skara Skyddsängels virtual reality testplatform. Denna plattform skapas för att assistera Skara Skyddsängel i deras arbete att utveckla och utvärdera belysningsdrönare för fotgängare och cyklister i områden där traditionell belysningsinfrastruktur inte är lönsam. Genom att erbjuda alternativ infrastuktur strävar projektet mot en ökad användning av mer miljövänliga transportmedel. Samtliga av projektledarens krav är implementerade, såsom till exempel drönarhöjd, ljusvinkel och ljusintensitet. Dessutom finns några övriga funktioner implementerade, så som ljud från omgivningen för att göra miljön mer verklighetstrogen. Den slutgiltliga produkten är en fungerade testplatform med en miljö som efterliknar en väg på landsbygden utanför Skara. Denna plattform kommer hjälpa Skara Skyddsängel i att göra tester för att hitta optimala drönarinställningar / Skara Skyddsängel

This project is an elaboration of how luminaire design can provide for fundamental human needs. Visual needs in terms of task performance, orientability and visual comfort; emotional needs in terms of soothing feelings of safeness and cosiness; and biological needs in terms of circadian rhythm and resetting of our biological clock in the morning. These needs are tested through three bedroom scenarios named focus, contemplation and dawn, each with their own demands and desires on lighting qualities.  I have submerged into desired lighting qualities and atmosphere in a bedroom context; into how circadian rhythm can be promoted through lighting design; into how the perception of space can be effected through light; into how responsible use of natural resources can be achieved; and finally into what the impact and consequences of the design intervention are. The investigation is performed in a generic bedroom situation without daylight considerations. A prototype has been produced in order to perform observations and measurements.  Through the investigation I can state that luminaire design is able to provide for visual, emotional and biological needs. By simultaneously working with light qualities and shape of the luminaire, and having formulated the specific scenarios focus, contemplation and dawn, qualitative observations and experience could be supplemented by quantitative measurements and drive the design process forward towards intended lighting effects, characteristics and impacts on the human body and mind.
