Abstract:
Creating desirable layouts of building interiors is a complex task as designers have to manually adhere to various local and global considerations arising from competing practical and design considerations. In this work, we present an interactive design tool to create desirable floorplans by computationally conforming to such design constraints. Specifically, we support three types of constraints: (i) functional constraints such as number of rooms, connectivity among the rooms, target room areas, etc.; (ii) design considerations such as user modifications and preferences; and (iii) fabrication constraints such as cost and convenience of manufacturing. Based on user specifications, our system automatically generates multiple floor layouts with associated 3D geometry that all satisfy the design specifications and constraints, thus exposing only the desirable family of interior layouts to the user. In this work, we focus on precast concrete-based constructions, which lead to interesting discrete and continuous optimization possibilities. We test our framework on a range of complex real-world specifications and demonstrate the control and expressiveness of the exposed design space relieving the users of the task of manually adhering to non-local functional and fabrication constraints.
The algorithm runs in three phases: (i) A layout is initially formed by space division complying with user specifications. (ii) Users can then interactively manipulate the suggested layouts by sliding an arbitrary wall segment forward or backward as well as swapping rooms. (iii) We build a model to support pre-cast concrete based construction with a given library of concrete slabs by automatically adjusting wall positions.
Various resulted layouts and an example of layout optimization via abstracted rectangular proxies, followed by layout regeneration and validation.
