  3. 22. Modeling wind-induced currents in lake Bolmen, Sweden, using TELEMAC 2D

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Prasanjaya Bandara Ekanayake; [2021]
    Nyckelord :Bolmen Lake; TELEMAC 2D; Wind induced currents; QGIS; Blue Kenue; Technology and Engineering;

    Sammanfattning : Transport and material intermixing within lake systems have a significant impact on lake water quality. However, since researchers are primarily concerned with biological, environmental, and ecological aspects, physics and hydrodynamic behavior in lake water currents frequently receive less attention.

  5. 24. Simulated Laser Triangulation with Focus on Subsurface Scattering

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

    Författare :Hilma Kihl; Simon Källberg; [2021]
    Nyckelord :Laser triangulation; subsurface scattering; simulation; speckle pattern; Gaussian beam; Blender; spruce wood; blister package;

    Sammanfattning : Practical laser triangulation sessions were performed for each measurement object to obtain ground truth data. Three methods for laser line simulations were implemented: reshaping the built-in light sources of Blender, creating a texture projector and approximating a Gaussian beam as a light emitting volume.

  7. 25. Resolution Independent Path Rendering of Dynamic Geometry

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Niklas Persson; [2021]
    Nyckelord :computer graphics; vector graphics; path rendering; animation; resolution independent;

    Sammanfattning : Vector graphics rendering is the subject of a large number of research papers. However, many of them lack results regarding animated vector graphics despite its importance in many fields. In this thesis the resolution independent rendering of animated graphics is studied.
