Virtual Reality (VR) applications in medicine had significant improvements. 3D visualization of various anatomical parts using advanced medical scanner images, anatomy education, surgery operation simulation, virtual simulator for laparoscopic skills, virtual endoscopy, psychotherapy and rehabilitation techniques are some of the VR applications in medicine. Integration of the haptic devices into VR applications increased quality of the systems. By using haptic devices, the user can not only feed information to the computer but can receive information from the computer in the form of a felt sensation on some part of the body. In this thesis a dental education simulator is developed by using a computer, a monitor, a haptic device and stereoscopic devices. The entire jaw model, all teeth and decay is modeled in the virtual environment. It is possible to diagnose the decay and remove the decay region by using different dental instruments developed in the system. Different graphical rendering methods like Marching Cubes, Ray-casting on GPU are implemented and compared. The system is used by dentists from METU Health Center and Ankara University and performance tests are applied to the system. By this system it is expected to develop a more realistic and effective preclinical education. Several advantages offered by the simulator include: an effective learning environment without undue fear of mistakes, facilitation of repetition, provision of opportunities to quantitatively assess student skills, rapid training environment without an instructor and lower the cost of dentist training.

Development of a material cutting model for haptic rendering applications
Üner, Görkem; Konukseven, Erhan İlhan; Department of Mechanical Engineering (2007)
Haptic devices and haptic rendering is an important topic in the burgeoning field of virtual reality applications. In this thesis, I describe the design and implementation of a cutting force model integrating a haptic device, the PHANToM, with a high powered computer. My goal was to build a six degree of freedom force model to allow user to interact with three dimensional deformable objects. Methods for haptic rendering including graphical rendering, collision detection and force feedback are illustrate...
Visualization in virtual reality: a systematic review
Korkut, Elif Hilal; Sürer, Elif (2023-01-01)
Rapidly growing virtual reality (VR) technologies and techniques have gained importance over the past few years, and academics and practitioners have been searching for efficient visualizations in VR. To date, the emphasis has been on the employment of game technologies. Despite the growing interest and potential, visualization studies have lacked a common baseline in the transition period of 2D visualizations to immersive ones. To this end, the presented study aims to provide a systematic literature review...

Developing building information modelling based virtual reality and mixed reality environments for architectural design and improving user interactions with serious games
Ergün, Oğuzcan.; Sürer, Elif; Department of Modeling and Simulation (2019)
Virtual Reality (VR) provides an interactive experience for its users in a fully artificial computer-simulated environment while Mixed Reality (MR) forms environments by mixing the real world and the virtual world elements together. In the first part of this thesis, an architectural visualization and design tool, which is based on Building Information Modeling (BIM), is developed for VR, MR and personal computer (PC) environments. BIM provides detailed information and tools to professionals so that they can...
Design, development and manufacturing of an all terrain modular robot platform
Kul, Mustafa Cihangir; Koku, Ahmet Buğra; Department of Mechanical Engineering (2010)
The aim of this thesis is to create a flexible multi-purpose modular all terrain robot platform, which has the potential to be used in commercial applications as well as in education and research. In developing this robot platform, it is aimed to use readily available commercial products as much as possible in order to keep the cost of the product low, increase maintainability, and benefit from the improvements made to these components in time. The modularity is attained by designing a two wheeled base modu...
