It’s rob from hexler.net, here’s something I would like to poll people about concerning Syphon and visual apps on OS X in general being locked to OpenGL 2.1.
I am currently working on a couple of projects that (currently) include Syphon support, but I am also on the fence about actually ditching GL2 support in favor of a GL3 based renderer moving forward. I’ve had a look around what’s available app-wise for visualists on OS X and it seems to me everyone is kind of getting comfortable with the existing sort of baseline of coding against GL2 and the obvious implications of this (GLSL version/programmable shader stages/uniform buffers/etc.).
I am wondering what your opinion is on this and where you see Syphon regarding this in the future? Are there any plans to produce a GL3 based version at some point? I seem to recall seeing a project on GitHub that actually tries to do just that, but of course I understand that this move would probably break compatibility with existing servers/clients based on GL2 (for the “fast” way of sharing the textures on the GPU anyway).
As it stands now, I don’t see much problems for my own software to make the move, but Syphon is one of the more important things that I would hate to lose. I’d be more than willing to actually help out and contribute to any efforts in this direction though if there are any such plans.
I also seriously think it is time that more visual software should start making this move if we all want to start using a bit more up-to-date tech at some point, but I guess that’s a topic for a different forum.
All the best,

Once modern GL is supported, Syphon will work between legacy and core profile contexts no problem.
If you’d like to contribute (which would be great) perhaps that issue would be a good place for discussion.May 22, 2014 at 6:59 am #58670h3xl3rParticipant
Ha! Thanks for the swift reply! That’s music to my ears 🙂 I guess I hadn’t really thought that it would actually be possible to do cross-context-version sharing. Yay!
I’ll try to put my “money” where my mouth is and will dig a bit into the current source and the other github projects you’re linking in that issue thread.
