The Design of a Graphics Engine for the Development of Virtual Reality Applications

This work presents the design and the features of a flexible realtime 3D graphics engine aimed at the development of multimedia applications and collaborative virtual environments. The engine, called EnCIMA (Engine for Collaborative andImmersive Multimedia Applications), enables a fast development process of applications by providing a high level interface, which has been implemented using the C++object-oriented programming paradigm. The main features of the proposed engine are the support to scene management, ability to load static and animated 3D models, particle system effects, network connection management to support collaboration, and collision detection. In addition, the engine supports several specialized interaction devices such as 3D mice, haptic devices, 3D motion trackers, data-gloves, and joystickswith and without force feedback. The engine also enables the developer to choose the way the scene should be rendered to, i.e. using standard display devices, stereoscopy, or even several simultaneous projection for spatially immersive devices. As part of the evaluation process, we have compared the performance of EnCIMA to a game engine and two scene graph toolkits, through the use of a testbed application. The performanceresults and the wide variety of non-conventional interaction devices supported are evidences that EnCIMA can be considered a real time virtual reality engine

Crow Goes Hunting

Crow Goes Hunting is a 3D Narrative of a poem by the same name, created in the Unity engine. The project takes the viewer on an illustrated journey through Crow\u27s discovery of the destructive power of words

Captain Eagle vs Doctor Catastrophe

This project is designed as a challenge for only two artists and no techs. As an animation, it pushes our artistic abilities without requiring extensive technical knowledge and can still be used in a portfolio

Computer-Assisted Interactive Documentary and Performance Arts in Illimitable Space

This major component of the research described in this thesis is 3D computer graphics, specifically the realistic physics-based softbody simulation and haptic responsive environments. Minor components include advanced human-computer interaction environments, non-linear documentary storytelling, and theatre performance. The journey of this research has been unusual because it requires a researcher with solid knowledge and background in multiple disciplines; who also has to be creative and sensitive in order to combine the possible areas into a new research direction. [...] It focuses on the advanced computer graphics and emerges from experimental cinematic works and theatrical artistic practices. Some development content and installations are completed to prove and evaluate the described concepts and to be convincing. [...] To summarize, the resulting work involves not only artistic creativity, but solving or combining technological hurdles in motion tracking, pattern recognition, force feedback control, etc., with the available documentary footage on film, video, or images, and text via a variety of devices [....] and programming, and installing all the needed interfaces such that it all works in real-time. Thus, the contribution to the knowledge advancement is in solving these interfacing problems and the real-time aspects of the interaction that have uses in film industry, fashion industry, new age interactive theatre, computer games, and web-based technologies and services for entertainment and education. It also includes building up on this experience to integrate Kinect- and haptic-based interaction, artistic scenery rendering, and other forms of control. This research work connects all the research disciplines, seemingly disjoint fields of research, such as computer graphics, documentary film, interactive media, and theatre performance together.Comment: PhD thesis copy; 272 pages, 83 figures, 6 algorithm

Developing serious games for cultural heritage: a state-of-the-art review

Although the widespread use of gaming for leisure purposes has been well documented, the use of games to support cultural heritage purposes, such as historical teaching and learning, or for enhancing museum visits, has been less well considered. The state-of-the-art in serious game technology is identical to that of the state-of-the-art in entertainment games technology. As a result, the field of serious heritage games concerns itself with recent advances in computer games, real-time computer graphics, virtual and augmented reality and artificial intelligence. On the other hand, the main strengths of serious gaming applications may be generalised as being in the areas of communication, visual expression of information, collaboration mechanisms, interactivity and entertainment. In this report, we will focus on the state-of-the-art with respect to the theories, methods and technologies used in serious heritage games. We provide an overview of existing literature of relevance to the domain, discuss the strengths and weaknesses of the described methods and point out unsolved problems and challenges. In addition, several case studies illustrating the application of methods and technologies used in cultural heritage are presented

Design and creation of a virtual world of Petra, Jordan

Includes bibliographical references.This thesis presents the design and creation of a 3D virtual world of Petra, Jordan, based on the digital spatial documentation of this UNESCO World Heritage Site by the Zamani project. Creating digital records of the spatial domain of heritage sites is a well-established practice that employs the technologies of laser scanning, GPS and traditional surveys, aerial and close range photogrammetry, and 360-degree panorama photography to capture spatial data of a site. Processing this data to produce textured 3D models, sections elevations, GISs, and panorama tours to has led to the establishment of the field of virtual heritage. Applications to view this spatial data are considered too specialised to be used by the general public with only trained heritage practitioners being able to use the data. Additionally, data viewing platforms have not been designed to allow for the viewing of combinations of 3D data in an intuitive and engaging manner as currently each spatial data type must be viewed by independent software. Therefore a fully integrated software platform is needed which would allow any interested person, without prior training, easy access to a combination of spatial data, from anywhere in the world. This study seeks to provide a solution to the above requirement by using a game engine to assimilate spatial data of heritage sites in a 3D virtual environment where a virtual visitor is able to interactively engage with combinations of spatial data. The study first begins with an analysis of what virtual heritage applications, in the form of virtual environments, have been created, and the elements that were used in their creation. These elements are then applied to the design and creation of the virtual world of Petra

Hikari Michi: Studying Immersion in Games Using the Oculus Rift and Leap Motion Controller

Game developers are always searching for new, creative ways to immerse players into their games, whether it be through gameplay, input, or output. As aspiring games developers ourselves, we pursued this project with the goal of building a game that made an enriching and engaging experience through its gameplay, input, and output. For this game, we made use of the Leap Motion hand and finger movement capturing device and the Oculus Rift virtual reality head mounted display alongside the C4 Game Engine. Through this project, we hope to provide players with a fun, immersive game play experience and hopefully be a source of inspiration for virtual reality game developers in the future
