[vtk-developers] Apple deprecates OpenGL in macOS 10.14

[Sean McBride]

Hi all,

In addition to what others have said...

- OpenGL ES is also deprecated on iOS
- indeed deprecation doesn't mean it will be removed soon. It does mean however, that's it's likely to work worse and worse over the years, and see few to no bug fixes.
- Yes, Carbon was deprecated years ago, and yet it's still there. But it's only available to 32 bit processes, it never made the jump to 64 bit.  Something analogous could occur with OpenGL.
- if you use Apple's 'app stores', then note that a policy of theirs is to sometimes/always (dunno) reject apps that use deprecated APIs.

Even on other platforms, OpenGL has a hazy future.  Vulkan may be a good direction for VTK.  And MoltenVK could be the solution for Apple platforms.  Happily it was open sourced recently!

Cheers,
