| This thesis introduces the Medical Visualizer (MedVis), a real-time visualization system for analyzing medical volumetric data in various virtual environments, such as parallax barrier autostereoscopic displays, dual-projector screens and immersive environments such as the CAVE. Direct volume rendering is used for visualizing the details of medical volumetric data sets without intermediate geometric representations. By interactively manipulating the color and transparency functions, radiologists can either inspect the data set as a whole or focus on a specific region. In this system, 3D texture hardware is employed to accelerate the rendering process. The system is designed to be platform independent, as all virtual reality functions are separated from kernel functions. Due to the modular design, it can be easily extended to other virtual environments, and new functions can be incorporated rapidly. |
