  1. 1. Influence of Varying Electric Light Distribution on Melanopic Equivalent Daylight Illuminance and Lighting Energy Use

    University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö; Lunds universitet/Avdelningen för Energi och byggnadsdesign

    Author : Rebecka Ståhl; Parvathy Biju; [2023]
    Keywords : Alertness; Circadian Entrainment; Clear Sky; Correlated Colour Temperature; Daylighting; Direct Electric Lighting; Direct-Indirect Electric Lighting; Energy-Efficiency; Grasshopper; Integrative Lighting; LARK 2.0; Melanopic Equivalent Daylight Illuminance; Overcast Sky; Photopic Illuminance; Spectral Power Distribution.; Technology and Engineering;

    Abstract : Human beings in modern society spend more than 90% of their time indoors to live, work, and socialize. To improve health, quality of life and task performance, integrative lighting is designed to give the right light at the right time at the eye to stimulate circadian entrainment. READ MORE

  3. 2. Performance Evaluation of (Spherical) Harmonics Virtual Lights for Real-time Global Illumination using Vulkan

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Simon Hultsborn; [2023]
    Keywords : Spherical harmonics; Global illumination; Computer graphics; Optimization;

    Abstract : Background. Global illumination is not trivial to compute in real-time computer graphics. One approximate solution is to distribute virtual light sources from a primary light, to then apply direct light calculations to said virtual lights. This can effectively estimate two-bounce illumination. READ MORE

  4. 3. Evaluation of Performance and Image Quality for Voxel Cone Tracing

    University essay from Mälardalens universitet/Akademin för innovation, design och teknik

    Author : Johannes Finn; [2022]
    Keywords : computer graphics; voxel cone tracing; voxel-based rendering;

    Abstract : Voxel cone tracing (VCT) is a rendering method designed to approximate global illumination in a fast and efficient way. Global illumination means to render not only the direct lighting of a scene but also light from indirect sources, simulating how light in the real-world tend to bounce around and illuminate even the areas that are occluded from a direct light source.

  5. 4. Automatic spotlight distribution for indirect illumination

    University essay from Blekinge Tekniska Högskola/Institutionen för kreativa teknologier

    Author : Lukas Orsvärn; [2014]
    Keywords : Reflective shadow map; global illumination; spotlight;

    Abstract : Context. Indirect illumination – the light contribution from bounce light in an environment – is an important effect when creating realistic images. Historically it has been approximated very poorly by applying a constant ambient term. READ MORE

  6. 5. Ambient Occlusion for Dynamic Objects and Procedural Environments

    University essay from Institutionen för systemteknik; Tekniska högskolan

    Author : Joel Jansson; [2013]
    Keywords : SSAO; Ambient Occlusion; Global Illumination; Real-Time Rendering; Computer Graphics;

    Abstract : In computer graphics, lighting is an important area. To simulate shadows from area light sources, indirect lighting and shadows from indirect light, a class of algorithms commonly known as global illumination algorithms can be used. READ MORE
