Infrastructure design using 3D reality data

Abstract:

In an example embodiment, a design application receives in its graphical user interface (GUI) user input specifying a boundary of a design region of a 3-D reality model of a site. A ground detection process detects a plurality of ground points within the design region that represent ground. A terrain creation process generates a 2.5D terrain mesh for the design region. A clipping process clips around the design region to show the 2.5D terrain mesh within the design region. A CAD modeling process is then used to place one or more 3-D CAD objects that represent planned infrastructure upon the 2.5D terrain mesh within the design region. The design application displays in the GUI the created combined view including the 3-D CAD objects placed upon the 2.5D terrain mesh within the design region, surrounded by a remaining part of the 3-D reality model that provides context.
