Bildsynthese durch Raytracing gewinnt durch Hardware-Unterstützung in Verbraucher-Grafikkarten eine immer größer werdende Relevanz. Der Linespace dient dabei als eine neue, vielversprechende Beschleunigungsstruktur. Durch seine richtungsbasierte Natur ist es sinnvoll, ihn in andere Datenstrukturen zu integrieren. Bisher wurde er in ein Uniform-Grid integriert. Problematisch werden einheitlich große Voxel allerdings bei Szenen mit variierbarem Detailgrad. Diese Arbeit führt den adaptiven Linespace ein, eine Kombination aus Octree und Linespace. Die Struktur wird hinsichtlich ihrer Beschleunigungsfähigkeit untersucht und mit dem bisherigen Grid-Ansatz verglichen. Es wird gezeigt, dass der adaptive Linespace für hohe Grid-Auflösungen besser skaliert, durch eine ineffiziente GPU-Nutzung allerdings keine optimalen Werte erzielt.
Das „Templerhaus“ in Boppard.
Kunsthistorische Untersuchung eines spätromanischen Baudenkmals
(2019)
Die vorliegende Bachelorarbeit untersucht die Namens-, Besitz- und Nutzungsgeschichte des sogenannten Templerhauses, einem massiven Profanbau der Stauferzeit in Boppard (Rheinland-Pfalz). Nach einer Beschreibung des heutigen Erscheinungsbildes und der Erarbeitung früherer Zustände erfolgt ein stilkritischer Vergleich mit ausgewählten Beispielen der Umgebung, der Rekonstruktionsversuch früherer Bauphasen und eine Einordnung in den städtischen Kontext.
In dieser Arbeit wird das Echtzeitrendering von Wolken von der Theorie bis hin zur Entwicklung derselben behandelt. Dabei sollen die visuellen Eigenschaften der Wolken sowie die unterschiedliche Wolkentypen simuliert werden. Dabei ist die Berechnung der Beleuchtung essentiell für ein glaubwürdiges Ergebnis. Die Rendertechniken nutzen dabei unterschiedliche Noise-Texturen; für die Modulierung der Wolken sind es hauptsächlich Perlin- und Perlin-Worley-Texturen. Das Rendern der Wolken wird per Compute-Shader durchgeführt um die Echtzeitfähigkeit zu gewährleisten. Um die Performance zu steigern, werden Temporal Reprojektion und andere Optimierungstechniken angewendet.
This bachelor thesis investigates the utilization of the Wii Balance Board
in virtual reality applications. For the investigation a snowboard game is
implemented, in which the virtual avatar can be controlled with the pressure
sensors of the Wii Balance Board. The user should be able to move
playfully and intuitively through the virtual environment by balancing his
body. The immersiveness and the influence on motion sickness and cybersickness
will be investigated. In Addition, the Wii Balance Board will be
compared with the Xbox Controller. The aim of the work is to evaluate
whether the Wii Balance Board is able to allow free movement in virtual
environments and whether it is more advantageous to use it rather than
a conventional controller. The results of the survey indicate that the Wii
Balance Board has a positive influence on the immersivness of the game,
despite better game results by using a conventional controller. The survey
also reveals that the use of the Wii Balance Board is responsible for more
motion-sickness/cybersickness cases.
A growing flood of advertising and information as well a limited capacity to collect information present a challenge to marketing today. Marketing in general is very important for the success of a company. But the classic marketing theory which ignores the special characteristics of young companies dominates. A new company with a new idea and a new product meets an existing market with customers and established competitors. For an innovation-related founding context this is a special challenge.
In this bachelor thesis the subjects, entrepreneurship and marketing will be discussed first. In addition the special characteristics of young companies, the so-called liabilities will be explained. The meaning of the term entrepreneurial marketing is explained by detailed consideration of the close and wide conceptual understanding. Afterwards the comparison clarifies the difference to the classic marketing. As part of the literature review, the current state of research will be presented and the practical use will be examined in more detail based on the central approaches. The approaches are the guerrilla marketing, ambient marketing, sensation marketing, viral marketing and ambush marketing. How entrepreneurial marketing with the central approaches is used in a start-up company is analyzed by a qualitative investigation in the form of a case study.
The case study shows that unconventional marketing measures and low use of medium can have a large effect. The entrepreneurial marketing therefore offers an alternative to classic marketing because it pays attention to the special characteristics of a young start-up company. This bachelor thesis shows that the entrepreneurial marketing can convert the weaknesses of young founding companies into strengths and lead to superiority over the competition.
This thesis is about the design and the implementation of a virtual reality experience. The goal is to answer two questions: Is it possible to create an immersive virtual reality experience which is mainly using impulses and triggers to scare and frighten users? Secondly, is this immersion strong enough to create an illusion in which the user can't separate the real world from the virtual world? To realise this project the design program Unity3D as well as Visual Studios 2017 were used. Furthermore, in order to verify that the experience is indeed immersive for the user, an experiment with a sample size of seven people was created. Afterwards the candidates were interviewed via a questionnaire how they felt during the virtual reality application. As a result the study showed that the application has tendencies to be immersive but the users were still aware of the situation. It can be concluded that the immersion was not strong enough to fool users regarding the separation of virtual and real world.
The goal of this work is the induction, conception, implementation and evaluation of an interactive game application among Android. The game genre of the app is a 2D-Jump ‘n’ Run Side-Scroller, whose graphical implementation is based on the four elements earth, fire, water and wind. The application should have classic functions of a Jump ‘n’ Run game and allow the player to overcome the four game worlds to find the finish. The implementation is based on Unity Engine and Adobe Photoshop. A user test asks basic questions about the application and specific questions about the research question, which are then evaluated. The research question examines the connection between fun factor and color perception while playing the app. Represented by the natural color combinations of the four elements. At the end possibilities for expansion and future prospects will be discussed.
This Bachelor thesis describes the conception, implementation and evaluation of a playful augmented reality application for mobile devices. Building on the ARCore SDK, the game pARcours was developed, where the player can place virtual objects in the real environment to build their own parcours. This must be flown through with a likewise virtual aircraft. The main focus in the implementation of the game was on the interaction with the virtual objects and the collision detection of these with real surfaces. Furthermore, various input methods for building the parcours and controlling the aircrafts were examined. In a final evaluation both the game and the various input methods could be evaluated, as well as ARCore with regard to the development of augmented reality applications.
