| Abstract | In medicine the knowledge of relative placement and size of anatomical structures is indispensable, especially in surgery and treatment planning. Therefore, the visualization of medical data sets acquired by Computer Tomography (CT) and Magnetic Resonance Imaging (MRI) has become more and more important because it offers a three dimensional view on the underlying data even of inner structures. A virtual environment additionally enables a stereoscopic, and therefore natural, view. Further, input devices with six degrees of freedom provide an intuitive exploration of the data. Our application is very flexible with respect to different input and output devices, because having two equally immersive virtual environments, the user will always feel more immersed in the one more suitable to his requirements. The virtual environment used in this work is Studierstube, an enhanced virtual reality system. For volume rendering, we employ GPU based ray-casting because of its superior image quality and efficiency in comparison to slice-based approaches. ∗e-mail: kratz@vrvis.at †e-mail: msh@vrvis.at ‡e-mail:fuhrmann@vrvis.at §e-mail:splechtna@vrvis.at ¶e-mail:buehler@vrvis.at The main focus of this paper is the seamless integration of perspective high-quality direct volume rendering into virtual reality. We will present a system that realizes pixel accurate intersections between polygonal geometry and volumetric data. Intuitive interaction methods are provided at interactive frame rates including volume clipping and exploration of the dataset’s interior. As main application areas we propose education and pre-operative planning. |
