      I’m not gonna tell you I spent all day writing a buggy, incomplete implementation of OpenGL ES 1.0 on top of Metal, but I’m also not going to tell you I didn’t do that.

      Why GLES 1.0? Any problems with shaders translation?

      The aim was actually to stick to just the fixed-function pipeline for this exercise. I don’t think there’d be anything too tricky about the shader translation from, say, GLES 2.0 to Metal; it’s been done numerous times before.

          OFC. What can be really cool is to have a decent implementation of GL 4.5+ Core on top of Metal.

          How many apps want to target modern GL on the Mac but don’t want to move straight to Vulkan? I can’t imagine it’s a big number.

          It sounds like Apple was right when it announced GL was deprecated... 😀

          Well they kicked the hornet’s nest for developers who have running OpenGL projects.

          It’s not like the bits are disappearing any time soon, but the writing’s been on the wall for years. I was on stage at WWDC ‘16 not-so-subtly hinting at this, and I haven’t heard many complaints from developers who chose to adopt Metal in the meantime.

          Yeah I’m all into Metal. But clearly there’s still an outrage across many devs, even though their programs will continue to run normally. Anyways, UE4 and Unity already use Metal, and I’m sure it’ll gain adoption across more devs. That and Vulkan.
