📃 Paper | 🌍 Project

Tested Operating Systems

Ubuntu 22.04 | Mac OS 15 | Windows 11

1. Optimize/Visualize Section 6 Experiments:

• Run optimization:

  just build
  ./DiffCloth -demo  -mode optimize -seed {randseed}
  

  where {demooptions} is the name of the demos from the following options and {randseed} is an integer for random initialization of the initial guesses of the tasks.

  The corresponding option for each of the experiments is:

  • T-shirt: tshirt
  • Sphere: sphere
  • Hat: hat
  • Sock: sock
  • Dress: dress

The progress of the optimization is saved into the output/ directory of the root folder.

Blender Addon For Selecting vertex indexes

import bpy

# Ensure that we are in object mode
bpy.ops.object.mode_set(mode='OBJECT')

# Get the active object (assumes it's a mesh)
obj = bpy.context.active_object

# Get the selected vertices using list comprehension
selected_vertices = [v.index for v in obj.data.vertices if v.select]

# Print the list of selected vertices
print(selected_vertices)

abstract = {Cloth simulation has wide applications in computer animation, garment design, and robot-assisted dressing. This work presents a differentiable cloth simulator whose additional gradient information facilitates cloth-related applications. Our differentiable simulator extends a state-of-the-art cloth simulator based on Projective Dynamics (PD) and with dry frictional contact [Ly et al. 2020]. We draw inspiration from previous work [Du et al. 2021] to propose a fast and novel method for deriving gradients in PD-based cloth simulation with dry frictional contact. Furthermore, we conduct a comprehensive analysis and evaluation of the usefulness of gradients in contact-rich cloth simulation. Finally, we demonstrate the efficacy of our simulator in a number of downstream applications, including system identification, trajectory optimization for assisted dressing, closed-loop control, inverse design, and real-to-sim transfer. We observe a substantial speedup obtained from using our gradient information in solving most of these applications.},
