Hi, I’d like to share a technique for creating C++ and Python bindings. This approach allows you to develop your code both locally and cross-platform. The package includes a PYPI setup with GitHub Actions configured for Linux, Windows, and macOS, making it easy to install via pip in Rhino’s ScriptE…

I feel privileged for being a small part of this slide :innocent: [Screenshot 2025-06-09 at 12.21.17] Incredible work! Thanks for sharing!

@Petras_Vestartas Thank you for sharing your work! I wonder if it may be possible to use Rhino C++ from CPython that way? Then we don’t have to take the detour via .NET. Jess

This would be a dream! .NET layer slows things down a lot. Since rhino is not opensource you cannot do this. @eirannejad Is it technically possible to wrap any RhinoDoc method? For instance to add a single point to rhino.

We have discussed this, but are not actively working on the project. There are already a large number of nanobind based bindings written right here: rhino3dm/src/bindings at dev · mcneel/rhino3dm Libraries based on OpenNURBS with a RhinoCommon style - mcneel/rhino3dm …

link against the Rhino C++ SDK instead Do you think anyone from mcneel, in the near future, could make this working in terms of rhino integration? I am wondering how this kind of integration works when: a) you have open source opennurbs library b) you have a closed source rhino software

Open or closed source doesn’t matter. We have a C++ SDK for Rhino that DLLs can use. We can try to get this project structured for in-rhino use, but we’re all super busy right now with many other projects so it’s hard to make any promises.

Thank you very much for making it available !

Does this step exists for mac too? Installing Tools (Windows) This guide covers all the necessary tools required to author Rhino plugins in C/C++ on Windows.

Mac is still something we are trying to figure out. We are making a C++ SDK available for Mac in Rhino 9, but definitely don’t have all of the issues worked out yet.
