1. 21. Concepts of Hybrid Data Rendering

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

   Author : Torsten Gustafsson; [2017]
   Keywords : visualization; rendering; opengl; abuffer;

   Abstract : This thesis describes methods for advanced visualization of 3D data. Order-independent transparent data between multiple datasets of varying types can be combined using an A-buffer. In this thesis, an implementation of such a buffer is presented. An optimisation of the A-buffer, based on the discarding of unnecessary fragments will be presented. READ MORE

3. 22. 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

4. 23. 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

5. 24. GPU-Based Visualisation of Viewshed from Roads or Areas in a 3D Environment

   University essay from Linköpings universitet/Informationskodning

   Author : Heilmair Christoph; [2016]
   Keywords : viewshed; gpu; multiple observers; observer; graphics card; efficient; viewshed analysis; road; real-time; real time;

   Abstract : Viewshed refers to the calculation and visualisation of what part of a terrain isvisible from a given observer point. It is used within many fields, such as militaryplanning or telecommunication tower placement. READ MORE

6. 25. Design and Implementation of an Out-of-Core Globe Rendering System Using Multiple Map Services

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