Rhino WIP Feature: C++ SDK for Mac

Serengeti (Rhino WIP) Developer

Hi all!

The C++ SDK for Rhino for Mac is available from the link below, which contains a prototype SDK, a simple plug-in and some instructions for use.

This SDK will allow third party developers to write plug-ins for Rhino for Mac in C++. This feature has been available on Rhino for Windows since Rhino 2.0.

This isn’t an official API yet - and it will only run on Rhino WIP. We won’t be making this available for Rhino 8. It is basically exactly the same as the C++ SDK for WIndows, and provides the same level of low-level access to Rhino that you get with that API.

There is no support for MFC nor any Win32 API, but if you have an existing C++ plug-in you should find that porting your native code to the Mac is relatively straightforward.

Complete instructions for using the SDK are in the readme of the Github repository. Please respond to this thread with any questions or problems and we will get them fixed!

This is amazing, thanks!

@andy what are the chances that this will make it in the Rhino9 release?

Super work and thanks again!

We are very much hoping it will make the Rhino 9 release.

Hi @andy
It’s an amazing news! I assume Eto is the way to go for cross platform UI ?
Thanks

Hi @andy and @dan
I am trying to setup VSCode to run Mac SDK. It seems to be working.
But I am getting typical C++ linking errors. Can’t find AfxMac.h?

Here is git hub link

Also does not seem to run using Xcode. I left an issue on GitHub.

@arten

You must have these preprocessor defines for Debug builds:

GCC_PREPROCESSOR_DEFINITIONS = $(inherited) ON_COMPILER_CLANG ON_RUNTIME_APPLE RHINO_APPLE=1 _DEBUG=1 _GNU_SOURCE MY_ZCALLOC Z_PREFIX ON__DEBUG _UNICODE RHINO_V6_READY RHINO_THIRD_PARTY_OSX_PLUGIN_COMPILE

and this for Release:

GCC_PREPROCESSOR_DEFINITIONS = $(inherited) ON_COMPILER_CLANG ON_RUNTIME_APPLE RHINO_APPLE=1 _GNU_SOURCE MY_ZCALLOC Z_PREFIX NDEBUG=1 _UNICODE RHINO_V6_READY RHINO_THIRD_PARTY_OSX_PLUGIN_COMPILE

You’re using CMAKE - so I assume there is a way of defining those in the make file.

I don’t see any issues on the Github repo. What am I missing here?

Yes - use Eto :slight_smile:

With the advent of a C++ SDK for Rhino for macOS, will C++ scripting also come (back) to Grasshopper, like back in Rhino 5 for Windows?

13

I don’t recall ever supporting C++ scripting in any version of Rhino

I’m pretty sure there was a C++ scripting component in Grasshopper in Rhino 5, but I might be wrong. It has been a while.

I think I remember this wrong. I wasn’t even proficient in Python back then.

If there was c++ scripting, it was not written by McNeel

Thank you for your effort and work on Vray for Rhino! Many of my architect friends have been dreaming of finally being able to switch from SketchUp to Rhino on Macs and be able to render in Vray! Thanks!
