iOS + OpenGL ES 3.0 Support？

Does this library support iOS + OpenGL ES 3.0?

I have thought about OpenGL ES 3.0, I was targeting OpenGL 4.6 as that is what I wanted support for.

To be honest there wasn't a lot of community involvement and that is what I was hoping for as there is no way I could support this in entirety, but that never happened so it died on the vine so to speak.

MacOS almost went sane with your effort, but it seems the community is not strong enough to turn MacOS into something that could realistically compete with a fully-fledged Linux. VM's on MacOS still run on OpenGL 2.1, in now soon 2026 haha, can you believe it?
Last hope I guess is for the UTM community to pick it up (the OpenGL 4.6 effort, to be clear), even though they are also highly under-staffed and not the ones who should fix Apple's mess. utmapp/UTM#4285

I could look into OpenGL 3.3, it's not that hard.. but I would want to exclude all the hacks in the shaders for uniforms that have been fixed in subsequent versions.

It's not on my list but I am more than capable of doing the work.

If there are some minimum requirements give me a heads up and I will start looking into it.

I would just like people willing to read the rendering code for Metal and understand how the state translation works from OpenGL to Metal, once people understand that the rest is easy.

I started adding a new target for OpenGL ES

There is a new library libMGL_ES.dylib

I was able to create a dispatch table that only included ES functionality, It needs more testing but its a good start as I was able to rely on most of what I already had in 4.6.. I just had to limit the functions for this library.

Its a separate compile, you define MGL_GL_CORE for 4.6 and MGL_GL_ES (which the xcode project does) and you get to different dispatch tables

Well its a start.

Very cool, thank you so much for your valuable effort! Will try to make developers of relevant related projects increasingly aware of your project, UTM is already a good case as it would highly improve for many use cases if it had proper OpenGL support.
