  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.

  3. 2. View-Dependent Collision Detection and Response Using Octrees

    Kandidat-uppsats, Blekinge Tekniska Högskola/Institutionen för kreativa teknologier

    Författare :Albin Hermansson; [2016]
    Nyckelord :Collision; Octree; Pixel Area; Level-of-Detail; LoD;

    Sammanfattning : Context. Collision is a basic necessity in most simulated environments, especially video games, which demand user interaction. Octrees are a way to divide the simulated environments into smaller, more manageable parts,and is a hierarchical tree-structure, where each node has eight children. LÄS MER

  4. 3. An evaluation of grid based broad phase collision detection for real time interactive environments

    Kandidat-uppsats, Avdelningen för Industriell utveckling, IT och Samhällsbyggnad

    Författare :Jonas Liljeby; [2011]
    Nyckelord :collision detection; object culling; broad phase; octree; hierarchical grid;

    Sammanfattning : Detailed and exact collision detection for large amounts of objects has for a long time been a non real-time affair because of the immense amount of computations necessary. This was however not only because of the complexity of the algorithms but also because discussed of the computations would not have had to be done in the first place. LÄS MER
