Geometry and Attribute Compression for Voxel Scenes

Voxel-based approaches are today’s standard to encode volume data. Recently, directed acyclic graphs (DAGs) were successfully used for compression, but they are restricted to a single bit of (geometry) information per voxel. We present several methods to compress arbitrary data (e.g., colors, normals, or reflectance information). Our most...

Interactive Remote Rendering

In this thesis, we present an interactive remote volume-rendering system. Our system tries to bridge the gap between complex medical volume data and the patient. The user can easily upload their own data, which they receive from the clinician after a scan, which they can then visualize. Our application does not require any medical or volume...

Simulating Urban Area Development for Semantic Game Worlds

Active multi-camera navigation in video surveillance systems

Active cameras are increasingly used to extend the area coverage and to improve image quality in video surveillance. With such a pan-tilt-zoom camera, operators can control its rotation around two axes and can use an optical zoom to get a better shot. Although multiple video streams are monitored simultaneously on a large grid of displays, they...

Particle-based Visualization of Soft-Tissue: Deformation in the Human Orbit

Orbital fat is the soft tissue inside the eye socket, or orbit, that surrounds the eye muscles, eyeball, optic nerve and blood vessels. It plays an important role in the mechanical operation of the eye during eyeball rotation. Knowledge of how this orbital fat behaves is limited. It is important for surgeons to improve this knowledge to make...

Realistic Rendering Of Virtual Worlds

The problem posed to the authors concerns SketchaWorld, a terrain modeling framework that allows users to easily construct virtual worlds by means of sketching. Until now, the developers of SketchaWorld have focused on procedural content generation and have left its visual presentation largely untouched. The authors have been tasked to develop a...

Direct and comparative visualization techniques for HARDI Data

DWI is an MRI imaging technique used to gain information concerning the diffusion process in tissue. Using DTI techniques, a diffusion profile can be constructed for fiber tract analysis. Recently developed HARDI techniques increase the detail to visualization on the process of diffusion. While HARDI reconstruction methods are used to model the...

Shai: Scenario authoring for simulation games

With the advent of affordable and powerful game engines, simulation games have become an increasingly effective solution for organising virtual training sessions in areas such as incident response, safety supervision and medical services. These simulation games are replacing real-life training sessions, which are often expensive and time...
