1. 1. 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

3. 2. Matching of geometrically and topologically changing meshes

   University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

   Author : Kristoffer Jonsson; [2015]
   Keywords : mesh; meshes; matching; matchings; topology; geometry; manifold; compression; animation; animations; fluid; spherical harmonics; tensor; bijective; game; games; DICE;

   Abstract : The aim for this thesis is to develop a foundation for a compression system for animated mesh sequences, specifically under dynamic change of mesh geometry and topology. Compression of mesh sequences is of special interest in the game industry and this particular thesis is a part of an ongoing series of projects at EA DICE. READ MORE

4. 3. Real-time image based lighting with streaming HDR-light probe sequences

   University essay from Medie- och Informationsteknik; Tekniska högskolan

   Author : Saghi Hajisharif; [2012]
   Keywords : ;

   Abstract : This work presents a framework for shading of virtual objects using high dynamic range (HDR) light probe sequences in real-time. The method is based on using HDR environment map of the scene which is captured in an on-line process by HDR video camera as light probes [32]. READ MORE

5. 4. Real-time image based lighting with streaming HDR-light probe sequences

   University essay from Medie- och Informationsteknik; Tekniska högskolan

   Author : Saghi Hajisharif; [2012]
   Keywords : Picture Image Generation; Image based lighting; pre-computed radiance transfer; high dynamic range video;

   Abstract : This work presents a framework for shading of virtual objects using high dynamic range (HDR) light probe sequences in real-time. The method is based on using HDR environment map of the scene which is captured in an on-line process by HDR video camera as light probes. READ MORE

6. 5. Analysis of Spherical Harmonics and Singular Value Decomposition as Compression Tools in Image Processing.

   University essay from Institutionen för datavetenskap, fysik och matematik, DFM

   Author : Aamir Qamar; Islamud Din; Muhammad Abbas Khan; [2012]
   Keywords : Spherical Harmonics and Singular Value Decomposition;

   Abstract : Spherical Harmonics (SPHARM) and Singular Value Decomposition (SVD) utilize the orthogonal relations of its parameters to represent and process images. The process involve mapping of the image from its original parameter domain to a new domain where the processing is performed. This process induces distortion and smoothing is required. READ MORE
