Abstract
Embodiments relate to carving three dimensional models of buildings out of larger models of city blocks to make way for more detailed models. In accordance with one aspect of the invention, a computer-implemented method for carving a building from a first three-dimensional model is described. The first three-dimensional model may represent a city block. The three-dimensional model may include a plurality of polygons which represent one or more buildings in a three-dimensional environment. One or more polygons are identified as a portion of a roof, and roof portions that are not discontinuous are combined in roof meshes. Based on a roof mesh, a three-dimensional volume portion of a three-dimensional model is determined, which may represent a first building. The first building representation may then be carved from the three-dimensional model.
