  1. 1. Interactive out-of-core rendering and filtering of one billion stars measured by the ESA Gaia mission

    Master-uppsats, Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

    Författare :Adam Alsegård; [2018]
    Nyckelord :out-of-core rendering; large-scale visualization; hierarchical octree; GPU streaming; realtime filtering.;

    Sammanfattning : The purpose of this thesis was to visualize the 1.7 billion stars released by the European Space Agency, as the second data release (DR2) of their Gaia mission, in the open source software OpenSpace with interactive framerates and also to be able to filter the data in real-time.

    Sammanfattning : This report covers theory and comparison of techniques for rendering massive scale 3D geospa- tial planet data in a web browser. It also presents implementation details of a few of these tech- niques in WebGL and Javascript, using the Three.js [1] 3D library. LÄS MER

  5. 4. Out-of-Core Multi-Resolution Volume Rendering of Large Data Sets

    Uppsats för yrkesexamina på avancerad nivå, Medie- och Informationsteknik

    Författare :Fredrik Lundell; [2011]
    Nyckelord :out-of-core; volume rendering; raycasting; large datasets; gpgpu; streaming; multi-resolution; openCL; bricking; blocking; adaptive; intrablock interpolation; voreen;

    Sammanfattning : A modality device can today capture high resolution volumetric data sets and as the data resolutions increase so does the challenges of processing volumetric data through a visualization pipeline. Standard volume rendering pipelines often use a graphic processing unit (GPU) to accelerate rendering performance by taking beneficial use of the parallel architecture on such devices. LÄS MER

  7. 5. Real-time rendering of very large 3D scenes using hierarchical mesh simplification

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för teknik och naturvetenskap

    Författare :Daniel Jönsson; [2009]
    Nyckelord :terrain rendering; mesh decimation; mesh simplification; out-of-core; atmosphere rendering; large dataset visualization;

    Sammanfattning : Captured and generated 3D data can be so large that it creates a problem for today's computers since they do not fit into the main or graphics card memory. Therefore methods for handling and rendering the data must be developed. This thesis presents a way to pre-process and render out-of-core height map data for real time use. LÄS MER
