Installation

Follow these commands to install SMPLicit in your environment. The required libraries are standard, with the possible exception of Kaolin which requires a particular version to run with the current code.

git clone https://github.com/enriccorona/SMPLicit
cd SMPLicit
Install the dependencies listed in requirements.txt:
- pip install -r requirements.txt
In particular, we use Kaolin v0.1 (see installation command) which should be easy to install. However, if you want to use a later version, you might need to update the import to TriangleMesh in SMPLicit/SMPLicit.py
Download the SMPL model from here and place it in SMPLicit/utils/

To be able to import and use SMPLicit in another project, just use run python setup.py install in the main folder.

Usage

To check that everything is going well, run one of the test scripts under the examples folder. The first example will just show a simple T-Shirt on a standard shaped SMPL and visualize it using trimesh, to make sure everything is working.

cd examples/
python example.py

SMPLicit can represent clothes of different types, so the following example will also add lower-body clothes, hair and shoes into the example:

python example_fullbody.py

And finally one can interpolate between clothes of different types. For instance, moving between a jacket, tops, short or long sleeved T-Shirts. The following script will generate object meshes that represent these clothes and will be saved in interpolation/, below the main folder.

python interpolate.py

Fitting SMPLicit from a single image:

We used another script that builds on SMPL estimation to find the cloth types that best fit the cloth semantic segmentation. Please refer to the README under Fit_SMPLicit/.
