System and method for overlaying two-dimensional map data on a three-dimensional scene

摘要

A method for augmenting a three-dimensional (3D) scene with two-dimensional (2D) map data includes receiving 3D map data having a 3D geometry data and imagery texture data. For a specified perspective of a virtual camera in a 3D coordinate system, geometry of the 3D scene is rendered using the 3D geometry data, wherein the specified perspective includes a position and orientation relative to the 3D scene. A map texture is generated using the 2D map data in accordance with the perspective of the virtual camera in the 3D coordinate system, and the imagery texture and map texture are applied to the rendered geometry.
