Auto-3D-house Design from Structured User Requirements

We study the task of automated house design, which aims to automatically generate 3D houses from user requirements. However, in the automatic system, it is non-trivial due to the intrinsic complexity of house designing: 1) the understanding of user requirements, where the users can hardly provide high-quality requirements without any professional knowledge; 2) the design of house plan, which mainly focuses on how to capture the effective information from user requirements. To address the above issues, we propose an automatic house design framework, called auto-3D-house design (A3HD). Unlike the previous works that consider the user requirements in an unstructured way (e.g., natural language), we carefully design a structured list that divides the requirements into three parts (i.e., layout, outline, and style), which focus on the attributes of rooms, the outline of the building, and the style of decoration, respectively. Following the processing of architects, we construct a bubble diagram (i.e., graph) that covers the rooms′ attributes and relations under the constraint of outline. In addition, we take each outline as a combination of points and orders, ensuring that it can represent the outlines with arbitrary shapes. Then, we propose a graph feature generation module (GFGM) to capture layout features from the bubble diagrams and an outline feature generation module (OFGM) for outline features. Finally, we render 3D houses according to the given style requirements in a rule-based method. Experiments on two benchmark datasets (i.e., RPLAN and T3HM) demonstrate the effectiveness of our A3HD in terms of both quantitative and qualitative evaluation metrics.
