Pyorerun

We can rerun c3d files and display their original content. And also animate biorbd models from the pyomeca organization.

conda install -c conda-forge pyorerun rerun-sdk=0.21

conda install opensim-org::opensim # mandatory dependency

Rerun .c3d - As simple as that

import pyorerun as prr

prr.c3d("example.c3d")

rerun-.4.mp4

NOTE: Only handle markers, force plates, floor for now

Rerun Biorbd Models

from pyorerun import BiorbdModel, PhaseRerun

nb_frames = 10
nb_seconds = 0.1
t_span = np.linspace(0, nb_seconds, nb_frames)

model = BiorbdModel("models/Wu_Shoulder_Model_kinova_scaled_adjusted_2.bioMod")
q = np.zeros((model.model.nbQ(), nb_frames))

viz = PhaseRerun(t_span)
viz.add_animated_model(model, q)
viz.rerun("msk_model")

rerun_biorbd_model.mp4

Play with joint DoFs q, Live.

from pyorerun import LiveModelAnimation


model_path = "models/Wu_Shoulder_Model_kinova_scaled_adjusted_2.bioMod"
animation = LiveModelAnimation(model_path, with_q_charts=True)
animation.rerun()

From source

conda install -c conda-forge ezc3d rerun-sdk=0.21 trimesh numpy biorbd pyomeca tk imageio imageio-ffmpeg conda install opensim-org::opensim

Then, ensure it is accessible in your Python environment by installing the package:

pip install . or python setup.py install

On Linux

Rerun should work out-of-the-box on Mac and Windows, but on Linux, you need first to run:

sudo apt-get -y install \
    libclang-dev \
    libatk-bridge2.0 \
    libfontconfig1-dev \
    libfreetype6-dev \
    libglib2.0-dev \
    libgtk-3-dev \
    libssl-dev \
    libxcb-render0-dev \
    libxcb-shape0-dev \
    libxcb-xfixes0-dev \
    libxkbcommon-dev \
