Computational Design of Wiring Layout on Tight Suits with Minimal Motion Resistance
An increasing number of electronics are directly embedded on the clothing to
monitor human status (e.g., skeletal motion) or provide haptic feedback. A
specific challenge to prototype and fabricate such a clothing is to design the
wiring layout, while minimizing the intervention to human motion. We address
this challenge by formulating the topological optimization problem on the
clothing surface as a deformation-weighted Steiner tree problem on a 3D
clothing mesh. Our method proposed an energy function for minimizing strain
energy in the wiring area under different motions, regularized by its total
length. We built the physical prototype to verify the effectiveness of our
method and conducted user study with participants of both design experts and
smart cloth users. On three types of commercial products of smart clothing, the
optimized layout design reduced wire strain energy by an average of 77% among
248 actions compared to baseline design, and 18% over the expert design.Comment: This work is accepted at SIGGRAPH ASIA 2023(Conference Track
NeuroGF: A Neural Representation for Fast Geodesic Distance and Path Queries
Geodesics are essential in many geometry processing applications. However,
traditional algorithms for computing geodesic distances and paths on 3D mesh
models are often inefficient and slow. This makes them impractical for
scenarios that require extensive querying of arbitrary point-to-point
geodesics. Although neural implicit representations have emerged as a popular
way of representing 3D shape geometries, there is still no research on
representing geodesics with deep implicit functions. To bridge this gap, this
paper presents the first attempt to represent geodesics on 3D mesh models using
neural implicit functions. Specifically, we introduce neural geodesic fields
(NeuroGFs), which are learned to represent the all-pairs geodesics of a given
mesh. By using NeuroGFs, we can efficiently and accurately answer queries of
arbitrary point-to-point geodesic distances and paths, overcoming the
limitations of traditional algorithms. Evaluations on common 3D models show
that NeuroGFs exhibit exceptional performance in solving the single-source
all-destination (SSAD) and point-to-point geodesics, and achieve high accuracy
consistently. Moreover, NeuroGFs offer the unique advantage of encoding both 3D
geometry and geodesics in a unified representation. Code is made available at
