D3D is proprietary while OpenGL is open standard. >It is by far the better of the two APIs I highly disagree. Do you have any examples? >Linux desktops is going to be based on Microsoft's RDP What?? I've seen plenty of VNC in the wild, but yet to see any RDP

A remote compositor that uses FreeRDP as its transport protocol was just checked into the Wayland mainline.

I highly disagree. Do you have any examples? OpenGL is a dog's breakfast of an API. It's everything an API shouldn't be -- stateful, verbose, and committee-driven. Just take a look at Valve's .PDF. An OpenGL programmer spends a large part of his/her time trying to maintain a mental model of the underlying driver's state and behavior. And God(s) help you if you step off the path used by popular applications and game engines. You can expect combinatorial bugs out the wazoo, again because the API and driver layers are so stateful. I agree with the grandparent -- it's well past time that a D3D-like API was adopted by other players. I've used OpenGL since the Quake 1 days and I've never understood why so many people sing its praises. The days when D3D was an inferior API are more than a decade behind us.

  One reason to sing opengl's praises - cross platform.

    That's bullshit. In practice different GPU parts support different subsets of OpenGL's shader model, leading to broken graphics depending on the GPU. This is a huge problem in, for example, Android games, where you have to test on just about every device to see what works and what doesn't. OpenGL is cross-platform because it's legacy. It is primarily of interest to outdated CAD software vendors, because that's who's driving the API specs, hence why it took so long for the fixed-function pipeline to finally be dropped. Modern CAD vendors, such as Autodesk, render through a Direct3D pipeline.

      The Android issue is entirely caused by shitty drivers. Pretty much all mobile hardware after the original iPhone fully supports OpenGL ES 2.0 shaders which haven't changed since inception.

      Dont project the driver and the implementation issues onto the api. Have you looked at programming using the core opengl context in opengl 3.2?

  Being verbose and committee-driven need not condemn a thing; Ada the programming language is both and is leaps and bounds better than its nearest competitor (C++). but programming opengl still feels like setting up a rube goldberg machine for its initial run
