1. A computer-based method for interactively viewing a vector animation sequence, wherein the vector animation sequence includes a first vector image and a second vector image that are stored on a server computer, the second vector image being different than the first vector image, comprising:

  • receiving, by a client computer, an indexed look-up table that stores a plurality of local vector objects associated with tile regions of the first vector image;

    requesting, by the client computer from the server computer, at least one tile region of a pre-processed vector image that was generated from the second vector image, wherein the pre-processed vector image includes a plurality of tile regions and a plurality of local vector objects, each local vector object being associated with one of the tile regions;

    receiving, by the client computer from the server computer, local vector objects and local vector object indices associated with the requested at least one tile region of the pre-processed vector image;

    extracting, by the client computer, local vector objects from the indexed look-up table according to the local vector object indices received from the server computer; and

    rendering, by the client computer, the second vector image using the received local vector objects and the extracted local vector objects.
