Free-form Floor Plan Design using Differentiable Voronoi Diagram

 

[teaser]

|Paper PDF|

Publication

 


    Xuanyu Wu, Kenji Tojo, Nobuyuki Umetani, "Free-form Floor Plan
    Design using Differentiable Voronoi Diagram," In Proceedings of
    Pacific Graphics 2024

Abstract

 

Designing floor plans is difficult because various constraints must
be satisfied by the layouts of the internal walls. This paper
presents a novel shape representation and optimization method for
designing floor plans based on the Voronoi diagrams. Our Voronoi
diagram implicitly specifies the shape of the room using the distance
from the Voronoi sites, thus facilitating the topological changes in
the wall layout by moving these sites. Since the differentiation of
the explicit wall representation is readily available, our method can
incorporate various constraints, such as room areas and room
connectivity, into the optimization. We demonstrate that our method
can generate various floor plans while allowing users to
interactively change the constraints.

How to run

 

The demos are written in Rust. If you don't have Rust on your
computer, please install the Rust development environment. Here is
the list of commands that generate GIF animations of convergence.

The command run --example 0_shapeA --release results in following
animations (left: random seed = 0, right: random seed = 1)

[0_shapeA_0] [0_shapeA_1]

---------------------------------------------------------------------

The command run --example 1_shapeB --release results in following
animations (left: random seed = 0, right: random seed = 1)

[1_shapeB_0] [1_shapeB_1]

---------------------------------------------------------------------

The command run --example 2_shapeC --release results in following
animations (left: random seed = 4, right: random seed = 7)

[2_shapeC_4] [2_shapeC_7]

---------------------------------------------------------------------

The command run --example 3_duck --release results in following
animations (left: random seed = 0, right: random seed = 5)

[3_duck_0] [3_duck_5]
