  1. 1. Procedural Natural Texture Generation on a Global Scale

    University essay from Linköpings universitet/Informationskodning

    Author : Anna Pohl Lundgren; [2023]
    Keywords : computer graphics; procedural generation; procedural textures; gpu; image processing; satellite imagery; real time; real-time; shadow detection;

    Abstract : This Master’s thesis investigates the application of dynamically generated procedural terrain textures for texturing 3D representations of the Earth’s surface. The study explores techniques to overcome limitations of the currently most common method – projecting satellite imagery onto the mesh – such as insufficient resolution for close-up views and challenges in accommodating external lighting models.

  3. 2. Riparian buffer zones in agricultural landscapes : Their status today and their future as an ecological tool in Sweden

    University essay from Karlstads universitet

    Author : Mikaela Ignatiou Hadjicharalambous; [2021]
    Keywords : Riparian buffer zones; agriculture lanscapes; ecological tool; streams; kantzoner; lantbrukslandskap; ekologisk vertyg; vattendrag;

    Abstract : The application of intensive farming and cultivation practices, resulting in large-scale modification of the hydrology of streams and rivers and of the natural vegetation, has increased the need to find ways to mitigate the negative impact of this habitat degradation. Suitable design and creation of riparian buffer zones in agriculture areas, is by many considered the best remedial measure. READ MORE

  4. 3. Evaluation of pixel based and object based classification methods for land cover mapping with high spatial resolution satellite imagery, in the Amazonas, Brazil

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Linnea Jonsson; [2015]
    Keywords : support vector machine; maximum likelihood; SPOT-5; classification; geography; physical geography; RBF-kernel; OBIA; multiresolution segmentation; Earth and Environmental Sciences;

    Abstract : In the state of Acre, Brazil, there is ongoing land use change, where inhabitants of this part of the Amazonian rainforest practice shifting agriculture. Practicing this type of agriculture is, according to the SKY Rainforest Rescue organization, damaging to forest ecosystems. READ MORE

  5. 4. Per-face parameterization for Texture Mapping of Geometry in Real-Time

    University essay from Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska högskolan

    Author : Johan Noren; [2014]
    Keywords : meshcolors; mesh; colors; uv; texture; texturemapping; parametrization; dice; frostbite; mt; Datateknik; Datateknik;

    Abstract : We investigate the mesh colors method for per-face parameterization for texture-mapping of geometry, implemented in the game engine Frostbite 3, for the purpose of evaluating the method compared to traditional texture-mapping in a real-time application. Traditional UV-mapping often causes discontinuities which commonly results in visible seams in the end results. READ MORE

  6. 5. A Data-Parallel Graphics Pipeline Implemented in OpenCL

    University essay from Institutionen för systemteknik; Tekniska högskolan

    Author : Joel Ek; [2012]
    Keywords : Computer graphics; GPGPU; OpenCL; graphics pipeline; rasterization; texture filtering; parallelization;

    Abstract : This report documents implementation details, results, benchmarks and technical discussions for the work carried out within a master’s thesis at Linköping University. Within the master’s thesis, the field of software rendering is explored in the age of parallel computing. READ MORE
