Spatial information modeling of buildings using non-manifold topology via a 3D geometric modeling kernel and designscript

摘要

A method, apparatus, system, and computer program product provide the ability to utilize a spatial model. A first input body and a second input body are obtained. A non-regular Boolean operation is performed that combines the first input body and the second input body to create and output an output body. The output body is a spatial model represented by a non-manifold solid body. A topological property of the non-manifold solid body is exposed to select and control an attribute of a building component represented by the non-manifold solid body.

1. A computer-implemented method for utilizing a spatial model comprising:
(a) obtaining a first input body and a second input body for a building; (b) performing a non-regular Boolean operation combining the first input body and the second input body to create and output an output body, wherein:
(1) the output body comprises a spatial model represented by a non-manifold solid body, wherein the spatial model represents an enclosure of space of the building, and the building is partitioned into discrete cells representing interior spaces or rooms of the building; and(2) in the non-regular Boolean operation, external faces of the first input body and the second input body that are within the output body are retained thus becoming double-sided interior faces; and (c) exposing a topological property of the non-manifold solid body to select and control an attribute of a building component represented by the non-manifold solid body.
