Techniques for providing a refresh of a scene are disclosed. In some embodiments, a scene is divided into a plurality of fragments, and successive fragments comprising the plurality of fragments are transmitted in a refresh stream. In such cases, each fragment comprises a subset that includes fewer than all of a hierarchical set of nodes comprising the scene and provides less than a complete structure of the scene. The nodes included in the respective successive fragments and the number of fragments into which the scene is divided are such that a prescribed number of consecutive fragments starting from any point in the refresh stream provides sufficient data to refresh the scene. |
