In Getting Started I see that it uses VS2015. But the sample projects are configured for VS2017 toolset and What’s New mentions VS2017 too. So it’s a bit unclear if it supports VS2015, VS2017 or both.
Thanks in advance and sorry if it has been answered previously - I could not find.
Thanks for pointing out the out-of-date page. I’ve updated the content to reflect the need for Visual Studio 2017.
That said, you should be able to build with Visual Studio 2015. If you also have VS2017, just load the solution and then set the Platform Toolset for each requried project to Visual Studio 2015 (v140).
The openNURBS toolkit is used on several platforms, including Windows, macOS, iOS and Android.
Over the years, a number of different versions of Visual Studio have been used to develop openNURBS for Windows. A VS2017 solution is provided as that is the currently available version.
