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

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

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

    Abstract : 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. 22. Real-time Thermal Flow Predictions for Data Centers : Using the Lattice Boltzmann Method on Graphics Processing Units for Predicting Thermal Flow in Data Centers

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Johannes Sjölund; [2018]
    Keywords : data center; airflow; computational fluid dynamics CFD ; lattice boltzmann method LBM ;

    Abstract : The purpose of this master thesis is to investigate the usage of the Lattice Boltzmann Method (LBM) of Computational Fluid Dynamics (CFD) for real-time prediction of indoor air flows inside a data center module. Thermal prediction is useful in data centers for evaluating the placement of heat-generating equipment and air conditioning. READ MORE

  4. 23. Comparing 3D-Clipmaps and Sparse Voxel Octrees for voxelbased cone tracing

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Tomas Möre; Gustav Schneider; [2018]
    Keywords : ;

    Abstract : Voxel based cone tracing is a promising approach to approximate globalillumination for real-time applications. This technique utilizes a voxelfield approximating the original scene to retrieve the necessary radi-ance information during sampling. The simplest approach to creat-ing a voxel field is to use a 3D texture. READ MORE

  5. 24. Graphical User Interfaces for Multi-Touch Displays supporting Public Exploration and Guided Storytelling of Astronomical Visualizations

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

    Author : Hanna Johansson; Sofie Khullar; [2018]
    Keywords : OpenSpace; Astrovisualization; GUI; API; Multi-touch displays; Public exploration; Storytelling; UX;

    Abstract : This report presents the development and implementation of a graphical user interface (GUI) for multi-touch displays as well as an application programming interface (API) for guided storytelling of astronomical visualizations. The GUI and the API is built using web technologies and the GUI is rendered in an OpenGL environment. READ MORE

  6. 25. Particle Systems : A Comparison Between Octree-based and Screen Space Particle Collision

    University essay from Blekinge Tekniska Högskola/Institutionen för kreativa teknologier

    Author : Nils Kåvemark; Stevan Miloradovic; [2018]
    Keywords : Particle System; Octree; Textures; GPGPU.;

    Abstract : Background. Real-time applications like video games use particle systems for special effects to add visual aesthetics and realism. However, when complex behaviour that requires interaction between particles and geometry is desired, problems arise. The developer has to choose between having consistent and precise collisions or higher performance. READ MORE
