  1. 1. Efficient and Accurate Volume Rendering on Face-Centered and Body-Centered Cubic Grids

    University essay from Uppsala universitet/Avdelningen för visuell information och interaktion

    Author : Karl-Oskar Smed; [2015]
    Keywords : rendering; bcc; fcc;

    Abstract : The body centered cubic grid (BCC) and face centered cubic grid (FCC) offer improved sampling properties when compared to the cartesian grid. Despite this there is little software and hardware support for volume rendering of data stored in one of these grids. READ MORE

  3. 2. Interactive visualization of space weather data

    University essay from Medie- och Informationsteknik; Tekniska högskolan

    Author : Martin Törnros; [2013]
    Keywords : scientific visualization; volumetric rendering; ray casting in spherical coordinates; space weather; sun; coronal mass ejection; cme; NASA; Datateknik; Datateknik;

    Abstract : This work serves to present the background, approach, and selected results for the initial master thesis and prototyping phase of Open Space, a joint visualization software development project by National Aeronautics and Space Administration (NASA), Linköping University (LiU) and the American Museum of Natural History (AMNH). The thesis report provides a theoretical introduction to heliophysics, modeling of space weather events, volumetric rendering, and an understanding of how these relate in the bigger scope of Open Space.

  4. 3. Efficient Volume Rendering on the Face Centered and Body Centered Cubic Grids

    University essay from Institutionen för informationsteknologi

    Author : Max Morén; [2012]
    Keywords : ;

    Abstract : In volumetric visualization, the body centered cubic grid (BCC) and its reciprocal, the face centered cubic grid (FCC), are despite their good sampling properties  not well off regarding available rendering software and tools. Described in this thesis is the development of an extension for the volume rendering engine Voreen, implementing two recently presented  GPU accelerated reconstruction algorithms for these grids, along with a simple nearest neighbor method.

  5. 4. Out-of-Core Multi-Resolution Volume Rendering of Large Data Sets

    University essay from Medie- och Informationsteknik

    Author : Fredrik Lundell; [2011]
    Keywords : out-of-core; volume rendering; raycasting; large datasets; gpgpu; streaming; multi-resolution; openCL; bricking; blocking; adaptive; intrablock interpolation; voreen;

    Abstract : A modality device can today capture high resolution volumetric data sets and as the data resolutions increase so does the challenges of processing volumetric data through a visualization pipeline. Standard volume rendering pipelines often use a graphic processing unit (GPU) to accelerate rendering performance by taking beneficial use of the parallel architecture on such devices. READ MORE
