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

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

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

   Abstract : 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. READ MORE

3. 2. Optimization Methods for Direct Volume Rendering on the Client Side Web

   University essay from Linköpings universitet/Informationskodning

   Author : Tobias Nilsson; [2019]
   Keywords : Volume Visualization; Ray Casting; Optimization; GPU; Web;

   Abstract : 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. READ MORE

4. 3. Topology-guided analysis and visualization of charge density fields

   University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi; Linköpings universitet/Tekniska fakulteten

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

   Abstract : 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.

5. 4. Brain Tumor Volume Calculation : Segmentation and Visualization Using MR Images

   University essay from Biomedicinsk instrumentteknik; Tekniska högskolan

   Author : Fabian Balsiger; [2012]
   Keywords : ;

   Abstract : Background: Glioblastomas are highly aggressive and malignant brain tumors which are difficult to resect totally. The surgical extent of resection constitutes a key role due to its direct influence on the patient’s survival time. READ MORE

6. 5. Real-time DVR Illumination Methods for Ultrasound Data

   University essay from Institutionen för teknik och naturvetenskap

   Author : Erik Sundén; [2010]
   Keywords : Direct Volume Rendering; Illumination; Ultrasound; Ambient Occlusion; Shadows;

   Abstract : Ultrasound (US) volume data is noisy, so traditional methods for direct volume rendering (DVR) are less appropriate. Improved methods or new techniques are required. There are furthermore a high performance requirement and limited pre-processing to be considered in order for it to be used interactively, since the volume data might be time-varying. READ MORE
