1. 21. Multi-Volume Rendering in OpenSpace Using A-Buffers for Space Weather Visualizations

   University essay from Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska högskolan

   Author : Jonas Strandstedt; [2017]
   Keywords : nasa; space; space weather; scientific visualization; visualization; 3d; graphics; volumetric; rendering; opengl; order-independent transparency;

   Abstract : The work described in this thesis is part of the initial development of the open-source visualization software OpenSpace, a collaborative project between Linköping University (LiU), the National Aeronautics and Space Administration (NASA) and the American Museum of Natural History (AMNH). The report covers the background and implementation of a rendering system that enables OpenSpace to interactively visualize multiple overlapping space weather events. READ MORE

3. 22. Radiosity for Real-Time Simulations of Highly Tessellated Models

   University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

   Author : Henrik Edström; [2016-05-27]
   Keywords : radiosity; hierarchical radiosity global illumination; light mapping; face cluster radiosity; volume cluster radiosity; texture atlas.;

   Abstract : The accurate simulation of light is one of the most important aspects of computer graphics. Radiosity is a physically-based method that can generate view-independent solutions of the light scattering in a scene. READ MORE

4. 23. Spatial-temporal multi-modal visualization of volumetric simulation and in situ satellite data

   University essay from Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska högskolan

   Author : Emil Axelsson; Tomas Forsyth Rosin; [2015]
   Keywords : Datateknik; Datateknik;

   Abstract : This thesis describes the work done by two students from Link¨oping University during a five month stay at Community Coordinated Modelling Center (CCMC) at the National Aeronautics and Space Administration (NASA). The work includes the implementation of algorithms for rendering time-varying volume simulation data from space weather simulations hosted by the CCMC, as well as visualizing photo sequences taken by the Solar Dynamics Observatory (SDO) satellite orbiting Earth.

5. 24. Clustered Shading : Assigning arbitrarily shaped convex light volumes using conservative rasterization

   University essay from Blekinge Tekniska Högskola/Institutionen för kreativa teknologier

   Author : Kevin Örtegren; [2015]
   Keywords : clustered shading; lighting; light culling;

   Abstract : Context. In this thesis, a GPU-based light culling technique performed with conservative rasterization is presented. Accurate lighting calculations are expensive in real-time applications and the number of lights used in a typical virtual scene increases as real-time applications become more advanced. READ MORE

6. 25. 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
