Abstract: To provide smoothly scaleable map features on interactive digital maps, a first and a second sets of style parameters for rendering a map feature at a first zoom level and a second zoom level, respectively, are received. The first and second sets of style parameters are provided to a vertex shader. The vertex shader is configured to interpolate the first set of style parameters and the second set of style parameters to generate an interpolated set of style parameters for a certain zoom level between the first zoom level and the second zoom level, and render the map feature at the certain zoom level in accordance with the interpolated set of style parameters.

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.

Abstract translation: 指定用于在多个缩放级别渲染地图特征的各个视觉参数的样式参数作为索引数据结构存储在一个或多个统一变量中，所述一个或多个统一变量是（i）在渲染管线的多个阶段可访问的，（ii）在 执行渲染管道的多个阶段。 经由用户界面接收要显示地图特征的缩放级别的选择。 一个或多个索引（在典型情况下恰好一个）与所绘制的每个风格化顶点配对。 顶点着色器被配置为使用一个或多个索引从索引数据结构检索相应的样式参数，并使用检索到的样式参数将所选缩放级别的地图特征渲染。
