Pytorch ARAP

This module implements energy calculations and iterative solvers for the As-Rigid-As-Possible Surface Modelling method (Sorkine & Alexa, 2007).

Builds on PyTorch and PyTorch3D.

Installation

1. Clone into target repository
2. Optional: Install torch_batch_svd, from https://github.com/KinglittleQ/torch-batch-svd for improved SVD calculations. If this is not installed, torch.svd will be used.

Usage

For examples on how to use this module, see demo_loss.py for calculating the ARAP surface energy for as a loss function, and demo_solver.py for a full solver
