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 # not a mandatory dependency

Rerun .c3d - As simple as that

``` python3 import pyorerun as prr

prr.c3d("example.c3d") ```

Rerun Biorbd Models

``` python3 from pyorerun import BiorbdModel, PhaseRerun

nbframes = 10 nbseconds = 0.1 tspan = np.linspace(0, nbseconds, nb_frames)

model = BiorbdModel("models/WuShoulderModelkinovascaledadjusted2.bioMod") q = np.zeros((model.model.nbQ(), nb_frames))

viz = PhaseRerun(tspan) viz.addanimatedmodel(model, q) viz.rerun("mskmodel") ```

Play with joint DoFs q, Live.

``` python3 from pyorerun import LiveModelAnimation

modelpath = "models/WuShoulderModelkinovascaledadjusted2.bioMod" animation = LiveModelAnimation(modelpath, withqcharts=True) animation.rerun() ```

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

if you want to use the OpenSim, you also need to install separately: conda install -c 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 \ patchelf
