  1. 1. Efficient Implementation of Concurrent Data Structures on Multi-core and Many-core Architectures

    Author : Bapi Chatterjee; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Synchronization Primitives; Lock-free Binary search tree; Lock-free; Concurrent Data Structures;

    Abstract : Synchronization of concurrent threads is the central problem in order to design efficient concurrent data-structures. The compute systems widely available in market are increasingly becoming heterogeneous involving multi-core Central Processing Units (CPUs) and many-core Graphics Processing Units (GPUs). READ MORE

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

    Author : Jacob Munkberg; Lund University.; Lunds universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Graphics Hardware; Computer Graphics; Rasterization; Texture Compression; Culling;

    Abstract : 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. 3. Performance Improvements for the Rasterization Pipeline

    University dissertation from Department of Computer Science, Lund University

    Author : Jon Hasselgren; Lund University.; Lunds universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Rasterization; Computer Graphics; Graphics Hardware;

    Abstract : 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. READ MORE

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

    University dissertation from Department of Computer Science, Lund University

    Author : Björn M Johnsson; Lund University.; Lunds universitet.; [2014]
    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.

  5. 5. Sparse Voxel DAGs for Shadows and for Geometry with Colors

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Dan Dolonius; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; directed acyclic graph; octree; compression; voxel; geometry; shadows; colors;

    Abstract : Triangles are probably the most common format for shapes in computer graphics. Nevertheless, when high detail is desired, Sparse Voxel Octrees (SVO) and Sparse Voxel Directed Acyclic Graphs (DAG) can be considerably more memory efficient. One of the first practical use cases for DAGs was to use the structure to represent precomputed shadows. READ MORE
