Figure 1: We introduce a framework for synthesizing plausible scenes over interactively edited floor plans. Given an initial scene, a user can select an edge (wall) of it (a). The user can then expand (or shrink) the room shape, and our framework automatically adds (or removes) objects and continuously arranges objects (b). Users can add breakpoints (Red Box) to edit diverse floor plans (c). If a room is sufficiently large, our framework splits the room, adds new objects and arranges the existing objects (c, d, and e). Through a few operations, a floor plan that matches the user preference and contains plausible object arrangements is synthesized (f). Please see the supplementary video for interactive demos.
