Design, implementation and evaluation of novel 3D selection metaphors in Virtual Reality

This paper compares the efficiency and effectiveness of different selection methods in virtual environments. For this purpose, four novel selection metaphors based on an implementation in the Unreal Engine 4 are evaluated within the thesis.

Random forests for tracking in ultrasonic images

This thesis describes two possibilities for object tracking in medical ultra- sonic image data, which was provided by the CLUST2015 challenge.

Voxel Cone Tracing in OpenGL for rendering fully dynamic realtime global illumination

The goal of this thesis was to implement a lighting algorithm capable of rendering global illumination in real-time speed, which also is particularly suited for highly dynamic scenes. To achieve this, existing versions of the relatively novel Voxel Cone Tracing algorithm were used as reference.

A Volume-Based Penetration Measure for 6DOF Haptic Rendering of Streaming Point Clouds

I developed an algorithm to calculate the penetration volume of 3D CAD objects and unknown environments that are scanned live by a Microsoft Kinect. It is based on the inner sphere packings, which allow the algorithm to compute the approximate penetration volume in less than 1 millisecond. The algorithm was used to implement 6-DOF haptic rendering of arbitrary dynamic virtual environments.

A Programming Language for Procedural Content Generation in 3D Scenes

This thesis deals with the specification and implementation of a procedural API and programming language that can generate realistic looking asteroids.

Metaphors for Software Visualisation

The aim of this thesis was to explore graphical representations for visualising software in virtual reality.

Refactoring einer existierenden Code-Basis zur Simulation von Fisch-Schwärmen und Weiterentwicklung deren Verhaltensn

Das Ziel dieser Bachelorarbeit ist, die Codebasis der Fischschwärme aus dem Ba- chelorprojekt VR CoralReef neu zu strukturieren und zu erweitern, sodass eine ein- fache Integration von neuen Fischen und Schwärmen mit ihren Verhaltensmustern einfach umsetzbar ist. Dazu soll ein weiteres Modul implementiert werden, welches es ermöglicht die bisher nicht vermiedenen Kollisionen von Fischen mit Objekten zeitkritisch zu verhindern.

Redirected Walking in Virtual Reality during eye blinking

The main goal of this study was to find out whether users are able to notice Redirected Walking manipulations in Virtual Reality (VR) by changing their position in VR when these manipulations occur during eye blinking.

Tracking of Nonrigid Objects by Runtime Multi Domain Cluster Adaption

This thesis deals with the creation and investigation of an new approach for tracking general objects. It combines data of multiple sensors by clustering results of weak classifiers to classify the input data.

Rendering of Refraction at Transparent Polygonal Objects in Real-Time

The goal of this thesis was to realistically render two-sided refraction in real time.

Automatic Classification of Non-Mass Breast Lesions in Dynamic Contrast-Enhanced MR Images

Today, breast cancer is the highest frequent diagnosed cancer and the most common cause of death among women. The early detection of cancer tumors via the screening programs is the essential policy to increase survival rates. Malignant cancer tumor, in its developed stage, can attack the surrounding cells and metastasis to distant body parts. Metastasis is the main cause of death in patients. In order to prevent that, the malignant cancer tumor has to be detected and treated in its early stage.

Virtual Coral Reef: A Framework for the Procedural Growth of Corals based on L-Systems, Metaballs and Marching Cubes Algorithm

In cooperation with the Leibniz Center of Tropical Marine Ecology this master thesis aimed to represent the growth of a coral reef in which every coral is an individuum.

An Intelligent Middle-ware for Prototyping Intuitive User-Experience in Cars

The thesis focuses on anaylsing and presenting vehicle data in a virtual scenario in near real time.

Design and development of hardware and software for wireless Head-Mounted Displays

With the introduction of a new head-mounted displays models on the consumer market, the interest to those devices raised dramatically in the recent past. Although only a few wireless head-mounted display models are available today, there is a certain range of Vitrual- and Augmented Reality applications where those are needed. Existing solutions that allow using conventional HMDs for such applications wirelessly are either very expensive or too cumbersome.

This thesis is aimed to overcome those drawbacks with a new solution of a distributed design. Wired HMD is being connected to a compact, low-cost, portable computer that displays a real-time compressed video stream, transferred from a computer performing the actual rendering of an HMD-enabled application.

A Time-Based Adaptive Hybrid Sorting Algorithm on CPU and GPU with Application to Collision Detection

This thesis created a novel adaptive sorting algorithm that runs on CPU as well as GPU. It utilizes advantages from different underlying previously existing algorithms.
