Integrating custom c++ code into Python scripted plugin?

[AK Eric]

Asking for an engineer, since this isn't something I've ever tried:

He wants to integrate some custom (non-Maya) c++ code into a Maya plugin.  I have experience doing scriptedPlugins in Python, but not c++ ones. 

Obviously if you make a c++ plugin it'd be easy to integrate this other code.  So the question is:  Can you call to custom c++ code from a Python scripted plugin?  Or wrapper it somehow... or.... ?

Any thoughts?

thanks!

Interesting Question.  I'm pretty sure it could be done.  There's lots of ways available to wrap custom c++ code with a Python Binding, and I know that in the past I've called into COM interfaces on windows (to drive Photoshop) from my python scripts, but I'm not sure on the "how" for custom code.

I'm not an engineer, but hopefully you don't mind if I give this one a shot. :)

Step 1, write your C++ code.

Step 2, create bindings for Python

For step 2, you can use any of these.

- sip (from PyQt-land)

- shiboken (from PySide-land)

- Boost.Python

- pybind11

- ...

You compile it against the Python that ships with Maya, and viola, a regular importable library, like PyQt or PySide.

Adding on..

- Cython

- Built in ctypes library if you write a C shim

- Expose it to python through a Maya commands plugin that takes parameters

Thanks everyone, I'll pass that along.
