1. 1. Volume Rendering Simulation in Real-Time

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Enrique Perez Soler; [2020]
   Nyckelord :Volume Rendering; Real-time Simulation; Computer Graphics ; Shader ; Volymåtergivning; realtidssimulering; datorgrafik;

   Sammanfattning : Computer graphics is a branch of Computer Science that specializes in the virtual representation of real-life objects in a computer screen. While the past advancements in this field were commonly related to entertaining media industries such as video games and movies, these have found a use in others. LÄS MER

3. 2. Adaptive Feature based Level of Detail for Memory Restrained Interactive Direct Volume Rendering

   Master-uppsats, Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska högskolan

   Författare :Nils Andersson; Martin Marklund; [2020]
   Nyckelord :Level of detail; volumetric data; memory restrictions;

   Sammanfattning : The purpose of this thesis was to find and implement an adaptive method, based on given data and hardware, for selecting different level-of-detail whilst preserving visual quality to the best extent possible. Another important aspect of the new method was that it had to be performance effective, since the target platform was an interactive direct volume rendering application. LÄS MER

4. 3. Volume rendering with Marching cubes and async compute

   Kandidat-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

   Författare :Max Lukas Tlatlik; [2019]
   Nyckelord :Volume rendering; async compute; multi-engine;

   Sammanfattning : With the addition of the compute shader stage for GPGPU hardware it has becomepossible to run CPU like programs on modern GPU hardware. The greatest benefit can be seen for algorithms that are of highly parallel nature and in the case of volume rendering the Marching cubes algorithm makes for a great candidate due to its simplicity and parallel nature.

5. 4. Optimization Methods for Direct Volume Rendering on the Client Side Web

   Master-uppsats, Linköpings universitet/Informationskodning

   Författare :Tobias Nilsson; [2019]
   Nyckelord :Volume Visualization; Ray Casting; Optimization; GPU; Web;

   Sammanfattning : Volume visualization has been made available on the web using the Direct Volume Rendering (DVR) technique, powered by the WebGL 1 API. While the technique produces visually pleasing output, the performance of the prototypes that implement this leave much desired. 2017 saw the release of the next version of WebGL, WebGL 2. LÄS MER

7. 5. Topology-guided analysis and visualization of charge density fields

   Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi; Linköpings universitet/Tekniska fakulteten

   Författare :Elvis Jakobsson; [2019]
   Nyckelord :Visualization; Topology; Charge density; Direct Volume Rendering; Crystal structure;

   Sammanfattning : Direct volume rendering techniques for scalar fields make use of transfer functions to map optical properties to the field; the field can subsequently be visualized through the drawing of isosurfaces in the volume spanned by the field. The utility of this approach is limited in the case of nested or clustered structures with the same isovalue and further does not easily allow for quantitative measurements of the visualized data.
