Abstract:
Style parameters, which specify respective visual parameters for rendering a map feature at multiple zoom levels, are stored as an indexed data structure in one or more uniform variables that are (i) accessible in multiple stages of a rendering pipeline, (ii) unchanged during execution of the multiple stages of the rendering pipeline. A selection of a zoom level at which the map feature is to be displayed is received via a user interface. One or more indices (exactly one in a typical case) are paired with every stylized vertex drawn. The vertex shader is configured to retrieve corresponding style parameters from the indexed data structure using the one or more indices and render the map feature at the selected zoom level using the retrieved style parameters.
