Abstract
Official abstract text for this publication.
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for determining a building envelope. In one aspect, a method includes generating two-dimensional analytical faces; generating a three-dimensional shell bounding box that encompasses the analytical faces; determining, for each analytical face, one or more sample points; performing a flood-fill algorithm from a reference grid cell through other grid cells in the shell bounding box; casting one or more primary rays from each grid cell encountered by the flood-fill algorithm that does not contain any of the sample points but that directly neighbors a grid cell that does contain a sample point; for each ray, identifying as an exterior face the first analytical face within a vicinity of the grid cell from which the ray is cast that is intersected by the ray; and generating a building envelope based on the identified exterior faces.
First claim
Opening claim text (preview).
What is claimed is: 1. A method performed by data processing apparatus, the method comprising: generating a respective two-dimensional analytical face to represent each bounding element of a plurality of bounding elements that form at least a part of an analytical model; generating a three-dimensional shell bounding box that encompasses the analytical faces, the shell bounding box further comprising a plurality of three-dimensional grid cells arranged within the shell bounding box…
