Operations for caching to display panoramic images include repeatedly receiving an indication of one or both of a current geographic location and a current view direction for a user, receiving from a remote server a first plurality of image tiles of a first panoramic image of a predicted geographic location, caching the received first plurality of image tiles, and processing the cached first plurality of image tiles. The processing includes decompressing the cached first plurality of image tiles and storing the decompressed image tiles. When the current geographic location is at the predicted geographic location, rendering, using the stored decompressed tiles, the first panoramic image to a plurality of three-dimensional surfaces in a memory, wherein each of the plurality of three-dimensional surfaces corresponds to a respective portion of a sphere.

Caching in map systems for displaying panoramic images

Operations for efficient display of panoramic images include receiving control information a plurality of tiles of a panoramic image, identifying padding included in the received tiles, and processing the tiles to remove the padding. For each of the processed tiles, at least one patch is generated which maps at least a portion of each tile to a three-dimensional surface formed in a memory. Each patch includes a plurality of polygonal areas, and corresponds to a respective portion of a sphere. The panoramic image is drawn using the patches.
