Method of annotation across different locations

摘要

A computer-implemented method, system and computer-readable storage device provide functionality for managing location information for planar regions in two-dimensional views of a three-dimensional environment. A request is received for a first two-dimensional view of a three-dimensional environment that identifies a first planar region associated with content within the three-dimensional environment. The first two-dimensional view is rendered and displayed. A request is received for a second two-dimensional view from a second location. A distance and direction between the location of the first planar region and the location for the second view are determined and used to establish a second location of the planar region in the second two-dimensional view, and then use this information to help render and display the second two-dimensional view.

1. A computer-implemented method for managing location information for planar regions in two-dimensional views of a three-dimensional environment, the method comprising:
receiving a request for a first two-dimensional view of the three-dimensional environment, the first two-dimensional view being from a first location within the three-dimensional environment; performing, using one or more computing devices, a coordinate transformation on a rendered first two-dimensional view of the three dimensional environment to generate three-dimensional coordinates, the three-dimensional coordinates corresponding to the rendered first two-dimensional view and indicating at least a location of a first planar region within the three-dimensional environment; determining, using the one or more computing devices, a distance and a direction between a second location within the three-dimensional environment and the location of the first planar region based at least on the three-dimensional coordinates; and providing for display of a second two-dimensional view of the three-dimensional environment, the second two-dimensional view being from the second location in the three-dimensional environment, and being based on the determined distance and direction.
