The Factory scene in the figure shows the efficacy of the pairwise constraint. By modifying the weights of the pairwise distance and orientation terms, different groupings of work desks and chairs are obtained. The accessibility and visibility constraints acting together prevent the door and poster from being blocked. The Flower Shop provides a striking example of the effect of the pathways constraint, which maintains a clear path between the doors despite the dense coverage of the remainder of the room by flowers. For this scene, we change the position of the main door in each synthesis to il- lustrate different path generation solutions. The accessibility con- straint also prevents the.
