  2. 1. Hierarchical Variance Reduction Techniques for Monte Carlo Rendering

    Author : Petrik Clarberg; Institutionen för datavetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; computer graphics; Monte Carlo methods; importance sampling; hierarchical techniques; rendering;

    Abstract : Ever since the first three-dimensional computer graphics appeared half a century ago, the goal has been to model and simulate how light interacts with materials and objects to form an image. The ultimate goal is photorealistic rendering, where the created images reach a level of accuracy that makes them indistinguishable from photographs of the real world. READ MORE

  4. 2. Efficient Methods for Direct Volume Rendering of Large Data Sets

    Author : Patric Ljung; Anders Ynnerman; Thomas Ertl; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer Graphics; Scientific Visualization; Medical Imaging; Volume Rendering; Raycasting; Transfer Functions; Level-of-detail; Fuzzy Classification; Virtual Autopsies; Computer science; Datavetenskap;

    Abstract : Direct Volume Rendering (DVR) is a technique for creating images directly from a representation of a function defined over a three-dimensional domain. The technique has many application fields, such as scientific visualization and medical imaging. READ MORE

  5. 3. Real-Time GPU Techniques for Advanced Lighting Phenomena

    Author : Markus Billeter; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Shading; Rendering; Participating Media; Volumetric Shadows; Mobile Graphics; Scattering; Computer Graphics; GPGPU; Many-Light;

    Abstract : In the real world, the visual perception of an object is completely determined by the object's interactions with light. One large application of computer graphics is to visualize virtual objects and worlds in a fashion that is familiar to humans. Successfully emulating light and its effects on virtual objects therefore plays a central role. READ MORE

  6. 4. Techniques for Fast and High-Quality 3D Reconstruction of General Scenes

    Author : Sverker Rasmuson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; voxels; 3D reconstruction; computer vision; computer graphics; volumetric video;

    Abstract : This thesis is a collection of techniques used for 3D reconstruction; the creation of 3D models from real world objects or scenes. Given the increase in accuracy, robustness and speed of modern methods and algorithms, new and exciting applications of this technology is constantly appearing. READ MORE

  7. 5. Energy Analysis for Graphics Processors using Novel Methods & Efficient Multi-View Rendering

    Author : Björn M Johnsson; Institutionen för datavetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer graphics; energy consumption; energy measurements; multi-view rendering;

    Abstract : Real-time rendering is increasingly being performed on battery powered devices, such as laptops and mobile phones. As a result, performance in rendering time is not the only important factor, but the energy consumption is also becoming more and more important, as a lower energy usage directly translates to longer battery time.
