1. 1. Towards a High Quality Real-Time Graphics Pipeline

   Författare :Jacob Munkberg; Institutionen för datavetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Graphics Hardware; Computer Graphics; Rasterization; Texture Compression; Culling;

   Sammanfattning : Modern graphics hardware pipelines create photorealistic images with high geometric complexity in real time. The quality is constantly improving and advanced techniques from feature film visual effects, such as high dynamic range images and support for higher-order surface primitives, have recently been adopted.

3. 2. A Real-Time Soft Shadow Volume Algorithm

   Författare :Ulf Assarsson; Chalmers tekniska högskola; []
   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

4. 3. Performance Improvements for the Rasterization Pipeline

   Författare :Jon Hasselgren; Institutionen för datavetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Rasterization; Computer Graphics; Graphics Hardware;

   Sammanfattning : Performance improvements are always needed in computer graphics. Better performance frees up computational resources which can be used to increase the level of realism in the rendered images. Despite a very rapid development of graphics hardware, we are still far from the point where photo-realistic rendering can be done in real time. LÄS MER

5. 4. Efficient Compression and Rasterization Algorithms for Graphics Hardware

   Författare :Jon Hasselgren; Institutionen för datavetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Despite rapid development, modern graphics hardware is still much too slow to render photo-realistic images in real time, and it will most likely remain so if we rely only on yearly growth in hardware performance. Therefore, better algorithms are constantly needed in order to advance the field. LÄS MER

7. 5. Real-time Shading and Shadows using GPGPU Techniques

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

   Sammanfattning : 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. LÄS MER
