Abstract

Cache controller (120) for use in a system (180) comprising an image client (100) and an image server (140), the image client enabling a user to navigate through image data having at least three spatial dimensions by displaying views of the image data that are obtained from the image server in dependence on navigation requests of the user, and the cache controller comprising a processor (122) configured for obtaining content data indicative of a content shown in a current view of the image client (100), the current view representing a first viewpoint in the three spatial dimensions of the image data, the processor being further configured for predicting a view request of the image client in dependence on the content data, the view request corresponding to a view representing a second viewpoint in the three spatial dimensions of the image data, and a communication means (124) for obtaining the view from the image server in dependence on the view request, and for caching the view in a cache (130).
