The embedded Google Maps experience is about to improve with new developer features
This also adds several new capabilities for vector maps, such as Tilt and Rotation as well as WebGL Overlay View. The former is pretty simple: embedded maps are locked into an exclusively 2D orientation right now, and with tilt and rotation, users can experience embedded maps in an entirely new perspective with 67.5 degrees of tilt and full 360 rotation, complete with 3D models for buildings included. The latter, however, allows developers to build new mapping experiences by giving them direct hooks into the lifecycle of the WebGL rendering context used to render the vector map and allow developers two and three dimensional objects directly on the basemap, allowing them to be rendered at the same time as the map.
Sounds good? Then check out the official WebGL codelab and documentation to get started with these beta APIs.
