Browser based 3D visualization of multibody simulations.

Project Description


Visualization of multibody systems generated with PyDy.


This package relies on dependencies included in the SciPy stack (i.e. NumPy and matplotlib). These packages are not necessarily easy to install from source, so it is best to follow the instructions available on the SciPy installation page.

One example of installing the setuptools, NumPy, and matplotlib dependencies for Debian based Linux systems is to install from the apt package manager:

$ apt-get install python-setuptools python-numpy python-matplotlib

Once the dependencies are installed, then download the source and install with:

$ python install

This will automatically install the latest version of the final dependency SymPy if needed.


The Python tests require nose so get them with your package manager:

$ apt-get python-nose python-coverage

or pip:

$ pip install nose coverage

The tests can be run from the root directory with:

$ nosetests

And to see more detail with coverage, run:

$ nosetests -v --with-coverage --cover-package=pydy_viz

These are alternative ways to run the Python tests:

$ bin/test
$ python nosetests

For the Javascript tests the Jasmine and blanket.js libraries are used. Both of these libraries are included in pydy-viz with the source. To run the Javascript tests, go to the javascript library directory:

$ cd pydy_viz/static/js

Then run a simple HTTP Server with Python (the server is required due to some cross browser issues with blanket.js):

$ python -m SimpleHTTPServer

Now visit http://localhost:8000/SpecRunner.html in a webgl compliant browser.
