Abstract
For interactive viewing in medical imaging, pre-rendering is used to provide greater quality of the rendered images with a given computational power. For interactivity in viewing direction, two or more views are rendered for each location and provided as video to the viewer. The viewer selects a viewing direction interactively, and an image at the selected view direction is formed from the previously rendered images of the videos for the two or more views. In an alternative or additional approach, a video graph is created with videos of different segments of the graph. The videos are sequences of images representing change in location, camera parameters (e.g., zooming), and/or rendering settings. Once provided to the user, interactivity is provided by selection of the appropriate node of the video graph. The user may interactively select different locations and/or rendering settings available in the video graph, allowing interaction while benefiting from quality provided by pre-rendered video.
