Abstract

In this diploma thesis, we present the extension of web-based visualization framework Med3D, which allows users to view visualizations in virtual reality. We also implemented controlling visualized objects in virtual reality with HTC Vive controllers. It allows us to translate and rotate objects in all three directions, to ensure that the user gets the angle of view that he wants. In addition to extensions described above, we also implemented a volume ray casting method for visualizing volumetric data. Users can set a color, number of samples per ray and correction factor. Those settings are important for visualization results since input data can vary greatly and hardcoded parameters cannot provide the desired visualization results. We also tested the speed of our implementation of the algorithm (in FPS - frames per second) for different values of the number of samples and correction factor.
