This is huge, really huge for anyone who write DirectX games and want to make them run on OSX/Linux. This is basically what a part of Wine do, am I wrong?
I don't see why this is so "huge". Maybe you could explain? I think developing OpenGL-Games or porting them was never a big issues. Most 3d engines today even have those abstraction layers included anyway.
For the interested, google's Angle is the opposite : https://code.google.com/p/angleproject/
Now someone needs to start a project to find a large, documented subset for which ANGLE(ToGL(x)) = x so we can all get rid of this historical two-standards-that-do-exactly-the-same-thing nonsense.
Not sure here but don't all major engines already support OpenGL ootb ? Basically any engine thats runs on PS3/PS4 does like UnrealEngine, Cryengine, idTech, Unity and most indie/open source engines are OpenGL anyway. All engines that target Android/iOS are OpenGL too. Even for things like XNA which was Xbox/DirectX only there is MonoGame to port it to *nix platforms easily. So if you have rolled your own DirectX-onl…
I always wrote them so that all DirectX and Windows specific code was abstracted behind platform-agnostic generic interfaces. So, in theory, OpenGL support would be as simple as coding an OpenGL implementation of my generic graphics API. Probably a day or two's work, but I haven't had a compelling reason to do the OpenGL implementation yet.

PS3/PS4 commercial games do not use OpenGL and never have. This myth needs to die. http://scalibq.wordpress.com/2010/05/15/sony%E2%80%99s-plays...
"the advantage of a console: hardware is fixed". YEP! Why use an abstraction layer when you can just code to the metal.
Not being serious but it was interesting that happened

>>OpenGL is years behind D3D (not DirectX, it's not comparable!) in many areas, Explain please?
Complete lack of multicore rendering. You can practically issue render commands only from one thread. And there is no way to save bunch of commands anymore as display lists were deprecated. Also it's still very much state machine based. So you have to do a lot of individual calls to set everything up for actual draw call. I personally love OpenGL and use it on my work. However this is one of the biggest drawbacks on…
OpenGL has context sharing, which means several contexts in different threads sharing the same objects. You can issue commands as long as you synchronise access to objects yourself. In practice, that means filling buffers, rendering to an off-screen framebuffer, etc. from other threads.

its not a big deal... its just that most game code is hidden and buried so that most of the loud opinions and i have to say its good to see this but i'm mildly disappointed too... DirectX --> OpenGL is one thing, but a properly cross platform rendering interface that will work with DX, its flavour on 360, the novelties of Win8 and Xbone as well as PS3 gcm and gx/gx2 on nintendo platforms whilst dealing with the quirk…
