  2. 1. Real-Time Shading and Accurate Shadows Using GPGPU Techniques

    Author : Ola Olsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; virtual shadow-maps; real time; transparency; shading; shadows; rendering; shadow volumes; GPGPU; GPU;

    Abstract : Over the last 10-15 years, computer graphics hardware has evolved at a tremendous pace, with an exponential growth in the number of transistors. This evolution has transformed the Graphics Processing Unit (GPU) from an entirely fixed-function unit into a highly parallel general-purpose architecture that can be programmed using high-level programming languages.

  4. 2. Real-time Shading and Shadows using GPGPU Techniques

    Author : Ola Olsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; real-time; graphics; rendering; GPGPU; GPU-algorithms; deferred shading; ray tracing; shadows;

    Abstract : Modern GPUs have evolved to the point where they now offer a generality of programming that rivals CPUs, while at the same time sustaining much greater raw performance. In combination with a continued rapid increase in power, this generality has turned the GPU into an important platform for general purpose high performance computing algorithms. READ MORE

  5. 3. Image Analysis using the Physics of Light Scattering

    Author : Peter Nillius; KTH; []
    Keywords : computer vision; shading; illumination; reflectance; image irradiance;

    Abstract : Any generic computer vision algorithm must be able to copewith the variations in appearance of objects due to differentillumination conditions. While these variations in the shadingof a surface may seem a nuisance, they in fact containinformation about the world. READ MORE

  6. 4. Thermal stresses in load-bearing glass-timber components

    Author : Karin Lundstedt; Erik Serrano; Ola Dahlblom; Linnéuniversitetet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Thermal stresses; thermal failure; glass and wood construction; incident solar radiation; shading; cracks; temperature difference; finite element method.; Technology byts ev till Engineering ; Teknik;

    Abstract : Thermal stresses can arise in glass used in architectonic realisations in buildings as a result of solar irradiation:  that is, sunlight.  The magnitude of these thermal stresses depends on the temperature conditions in the glass in terms of the temperature differences between warm and cold areas.

  7. 5. Real-Time Algorithms and Intersection Test Methods for Computer Graphics

    Author : Tomas Möller; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; texture; ray tracing; radiosity; color; three-dimensional graphics and realism; virtual reality; algorithms; shadowing; shading;

    Abstract : In real-time computer graphics applications, at least three major forces are in conflict, namely, rendering speed, the level of realism, and interactivity. Therefore this thesis focuses on real-time algorithms that enhance the realism while maintaining high rendering speed, and on fast intersection test methods in order to speed up, for example, collision detection, picking processes and ray tracing.
