    Sammanfattning : Interactive systems for exploring and analysing medical three dimensional (3D) volume image data using techniques such as stereoscopic rendering and haptics can lead to new workflows for virtual surgery planning. This includes the design of patient-specific surgical guides and plates for additive manufacturing (3D printing). LÄS MER

  7. 5. Fast and High-Quality Visibility Determination

    Författare :Rasmus Barringer; Institutionen för datavetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; computer graphics; visibility; anti-aliasing; line sampling; ray tracing; rendering;

    Sammanfattning : Computer generated imagery is vital to the entertainment industry in the production of games and films, for example. It is also increasingly important for visualization in design, architecture, engineering, and medicine, to name a few. Improvements to rendering techniques come from a combination of improved algorithms and more powerful hardware. LÄS MER
