  1. 1. A Real-Time Soft Shadow Volume Algorithm

    Författare :Ulf Assarsson; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; three-dimensional graphics and realism; shading; pixel shaders; graphics hardware; shadowing; soft shadows; computer graphics;

    Sammanfattning : Rendering of shadows is a very important ingredient in three-dimensional graphics since they increase the level of realism and provide cues to spatial relationships. Area or volumetric light sources give rise to so called soft shadows, i.e., there is a smooth transition from no shadow to full shadow. LÄS MER

  3. 3. Multi-Camera Light Field Capture : Synchronization, Calibration, Depth Uncertainty, and System Design

    Författare :Elijs Dima; Mårten Sjöström; Roger Olsson; Ulf Assarsson; Mittuniversitetet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Light field; Camera systems; Multiview; Synchronization; Camera calibration;

    Sammanfattning : The digital camera is the technological counterpart to the human eye, enabling the observation and recording of events in the natural world. Since modern life increasingly depends on digital systems, cameras and especially multiple-camera systems are being widely used in applications that affect our society, ranging from multimedia production and surveillance to self-driving robot localization.
