Abstract
A graphics or image rendering system, such as a map image rendering system, receives image data from an image database, such as a map database, in the form of vector data having image features defined as sets of vertex data. The vertex data includes location data as well as an attribute reference that references a lookup table, in the form of a texture map, which is sent to or generated in the image rendering system. The attribute reference is then used by an image shader, such as a vertex shader, to determine the specific values for a plurality of vertex attributes or properties, as stored in the look up table. The image rendering system thus processes the vector data in a manner that allows for minimal data to be sent to the image rendering system from the image database as this system enables multiple vertex properties to be specified by a single attribute reference for each vertex data point.
