Abstract
A method or system for 3D rendering of map features on a client device. The client device receives a map tile and associated non-flat terrain data from a mapping server. The map tile represents a geographic area and features an object with a geometric base and height value. The terrain data gives elevation values for ground points. Using this data, the device's processors select a sample point on the map feature, determine its ground elevation, and calculate the feature's top surface elevation by adding the height value. Vertex ground elevations for the map tile's vertices are also determined, considering terrain variations. Vertex height values are calculated using these ground elevations and the top surface elevation. The map feature is then rendered in 3D, complete with vertical edges and a top surface, and displayed on the device's screen.
