I've been working, for a couple of weeks, on a python wrapper for OpenCascade 6.2.0 library. The development is in a very early stage, but i decided to release my work under a free licence (CeCILL) and set up different tools to enable collaborative work on this project.
You can find info, mailing list, SVN anonymous access, prebuilt binaries for Windows on the project web page:
You're welcome to help in any way(testing, bug report, patches, doc etc.). Only 20 out of 4000 objects are currently wrapped. Py++ code generator for Boost.Python library is used to achieve the work.
