Method, system and apparatus for dynamically generating map textures

A method, comprising:

• performing, by a computing device:
• obtaining map data via a wireless network, wherein the map data comprises vector graphics data describing one or more shapes for a map and one or more texture identifiers for the one or more shapes, but does not include respective textures for the one or more shapes;
• and
• rendering a map view based on the obtained map data for display on the computing device, said rendering comprising:
• for one or more of the shapes described for the map:
• obtaining, based on the texture identifier corresponding to the shape a particular texture definition for a texture to be generated for the shape;
• dynamically generating the texture for the shape according to the particular texture definition, wherein the texture is dynamically generated at the computing device instead of being downloaded via the wireless network;
• and
• applying the generated texture to the shape to render a current fill portion of the shape in the map view.

A multi-function device, comprising:

• a touch-sensitive display device;
• one or more processors;
• one or more memories storing program instructions for a map application executable on the one or more processors to:
• obtain map data via a wireless network, wherein the map data comprises vector graphics data describing one or more shapes for a map and one or more texture identifiers for the one or more shapes, but does not include respective textures for the one or more shapes;
• render a map view based on the obtained map data for display on the touch-sensitive display device, wherein said rendering comprises:
• for one or more of the shapes described for the map:
• obtain, based on the texture identifier corresponding to the shape, a particular texture definition for a texture to be generated for the shape;
• dynamically generate the texture for the shape according to the particular texture definition, wherein the texture is dynamically generated at the multi-function device instead of being downloaded via the wireless network;
• and
• apply the generated texture to the shape to render a current fill portion of the shape.

A non-transitory, computer-readable storage medium, storing program instructions, that when executed by one or more processors, cause the one or more processors to:

• obtain map data, via a wireless network connection, wherein the map data comprises vector graphics data describing one or more shapes for a map and one or more texture identifiers for the one or more shapes, but does not include respective textures for the one or more shapes;
• and
• render a map view based on the obtained map data, wherein to render the map view the program instructions cause the one or more processors to:
• for one or more of the shapes described for the map:
• obtain, based on the texture identifier corresponding to the shape, a particular texture definition for a texture to be generated for the shape;
• dynamically generate the texture for the shape according to the particular texture definition, wherein the texture is locally dynamically generated instead of being downloaded via the wireless network;
• and
• apply the generated texture to the shape to render a current fill portion of the shape.
