This package contains core functions for manipulating meshes and
visualizing them. It requires Python 3.5+ and is supported on
Linux and macOS operating systems.
The Mesh processing libraries support several of our projects such as
- CoMA: Convolutional Mesh Encoders for Generating 3D Faces
- FLAME: Learning a model of facial shape and expression from 4D scans
- MANO: Modeling and Capturing Hands and Bodies Together
- SMPL: A Skinned Multi-Person Linear Model
- VOCA: Voice Operated Character Animation
- RingNet: 3D Face Shape and Expression Reconstruction from an Image
- Expressive Body Capture: 3D Hands, Face, and Body from a Single Image
You first need to install the Boost <http://www.boost.org>_
libraries. You can compile your own local version or simply do on
Linux
$ sudo apt-get install libboost-dev
or on macOS
$ brew install boost
First, create a dedicated Python virtual environment and activate it:
$ python3 -m venv --copies my_venv
$ source my_venv/bin/activate
You should then compile and install the psbody-mesh package easily
using the Makefile:
$ BOOST_INCLUDE_DIRS=/path/to/boost/include make all
To run the tests, simply do:
$ make tests
A detailed documentation can be compiled using the Makefile:
$ make documentation
Starting from version 0.4 meshviewer ships with meshviewer -- a
program that allows you to display polygonal meshes produced by mesh
package.
The most straightforward use-case is viewing the mesh on the same machine where it is stored. To do this simply run
$ meshviewer view sphere.obj
This will create an interactive window with your mesh rendering. You
can render more than one mesh in the same window by passing several
paths to view command
$ meshviewer view sphere.obj cylinder.obj
This will arrange the subplots horizontally in a row. If you want a grid arrangement, you can specify the grid parameters explicitly
$ meshviewer view -nx 2 -ny 2 *.obj
It is also possible to view a mesh stored on a remote machine. To do this you need mesh to be installed on both the local and the remote machines. You start by opening an empty viewer window listening on a network port
(local) $ meshviewer open --port 3000
To stream a shape to this viewer you have to either pick a port that is visible from the remote machine or by manually exposing the port when connecting. For example, through SSH port forwarding
(local) $ ssh -R 3000:127.0.0.1:3000 user@host
Then on a remote machine you use view command pointing to the
locally forwarded port
(remote) $ meshviewer view -p 3000 sphere.obj
This should display the remote mesh on your local viewer. In case it does not it might be caused by the network connection being closed before the mesh could be sent. To work around this one can try increasing the timeout up to 1 second
(remote) $ meshviewer view -p 3000 --timeout 1 sphere.obj
To take a snapshot you should locally run a snap command
(local) $ meshviewer snap -p 3000 sphere.png
