In the last few years several multi-view display systems appeared increasing in size and the number of views that can be displayed. The increasing number of views allow for more realistic content with a high level of detail and complex lighting. For highest quality the images of synthetic scenes are usually ray traced. For large displays that are able to resolve a large amount of different views the number of viewing rays is enormous and it would take several month to render the content via ray tracing. One solution is to render only a few images and interpolate the remaining images with an image based rendering approach. This work introduces an algorithm that selects the best viewpoints for an image based rendering algorithm on the basis of given criteria. Special care is taken to cover occlusions and account for the dimension and angular resolution of multi-view displays.
