  1. 16. 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

  3. 17. Illumination properties and energy savings of a solar fiber optic lighting system balanced by artificial lights

    University essay from Fasta tillståndets fysik

    Author : David Lingfors; [2013]
    Keywords : daylight; optical fibers; solar light; energy saving; illuminance; luminous flux; correlated color temperature; color rendering index; luminous efficacy;

    Abstract : A solar fiber optic lighting system, SP3 from the Swedish company Parans Solar Lighting AB, has been installed in a study area/corridor test site. A collector is tracking the sun during daytime, focusing the direct sun irradiance via Fresnel lenses into optical fibers, which guide the solar light into the building. READ MORE

  4. 18. 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

  5. 19. Extending OGRE with Light Propagation Volumes

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Johan Elvek; [2012-08-13]
    Keywords : ;

    Abstract : OGRE is a popular open source rendering engine that offers an extensive set of core features. For more advanced rendering techniques, however, the engine must be extended in various ways. The term Global Illumination (GI) is often used to describe both the effects of inter-reflecting light, and the algorithms that achieve them. READ MORE

  6. 20. GPU Path Tracing

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Jincheng Li; [2012-02-28]
    Keywords : global illumination; path tracing; CUDA; massive light sources;

    Abstract : The goal of this work is to verify the possibility to utilize GPU for global illumination computations in a commercial software environment and explore an efficient way to do it. Path tracing with BVH as the acceleration data structure was implemented on GPU using CUDA successfully. READ MORE
