cloth-manipulation
Cloth manipulation through simulation with C-IPC
Installation
- Clone this repo.
- Clone C-IPC, install it's dependencies and build.
- Download blender, all recent versions should work.
- add this to .bashrc
export PATH="$PATH:/home/<name>/Blender/blender-3.0.0-linux-x64/"
Running an experiment
cd experiments/trajectory_height
blender scene.blend -b -P run_experiment.py -- -ht 0.25
Experiment flow
- Model piece of cloth in blender.
- Export as obj.
- Animate "base" path blender.
- Choose certain parameter values for base path and export as velocity trajectories.
- Execute these trajectories with C-IPC.
- Calculate losses of the final result.
CIPC build
Build with blender python. sudo apt install libpython3.9-dev if Python.h not found.
~/Blender/blender-3.0.0-linux-x64/3.0/python/bin/python3.9 build.py
Not sure if it is strictly necessary to use the Blender python to call build.py itself.
