What's used on platforms where Direct3D doesn't exist?

  OpenGL directly, no ?

    What about MacOS? Isn't OpenGL deprecated?

    ANGLE is used to to a source to source translation irrespective of backend - it normalizes the source input to various GPUs (dropping things that have historically been funky like comment parsing, #controls, dodgy constructs, disallowed constructs, etc) [Source: I worked on the original spec and spent a lot of time trying to prevent the more egregious security and privacy problems]

    Besides Apple devices, not on game consoles.

      ... but Google Chrome is not running on game consoles anyways ? Blink likely can, but then it does not necessarily use ANGLE, e.g. for instance QtWebEngine definitely does not use ANGLE on Mac / Linux but does native GL calls instead.

        PS 4 dashboard was done in WebGL. https://news.softpedia.com/news/The-PS4-UI-Is-Built-Using-WebGL-a-Web-3D-Graphics-Technology-400937.shtml https://news.softpedia.com/news/The-PS4-UI-Is-Built-Using-We...

          I don't understand your point. Yes, it's using WebGL. Do you think that it's going to do WebGL -> OpenGL ES 2/3 calls -> ANGLE -> Direct3D -> PS4 graphics driver (like it does on e.g. chrome on windows) ? No, it's likely doing WebGL -> PS4 proprietary graphics API -> PS4 graphics driver, not going through ANGLE or whatnot

            It uses a Chrome fork, so most likely Sony added LibGNM backend to ANGLE instead of redoing the whole graphics stack for Chrome.
            • jcelerier 6y ago
              but why would it go through ANGLE's libGLESv2.so and add a backend to that for the PS4 when the PS4 team could most likely provide their own libGLESv2 which maps directly to their driver (since they were doing that already for the PS3) ? As this is what chrome actually calls, gles functions.

                Unless I missed something, when were they doing that with PS3? The only effort to do any GL like stuff was on the PS2, with GL ES 1.0 + Cg, an effort that was dropped when almost no dev cared to use it. Other than that there was the PSGL library for PS2 Linux. Anyway, I did a bit more research and Chrome was actually only used for development purposes, they created their own WebGL engine on top of PhyreEngine for the console OS. https://www.youtube.com/watch?v=sIhtcUvi0BQ&t=3325s https://www.youtube.com/watch?v=sIhtcUvi0BQ&t=3325s

  There's no need to translate?
  • cptskippy 6y ago
    MacOS?
    • pjmlp 6y ago
      PS4, XBox?
      • cptskippy 6y ago
        Wouldn't Xbox use Direct3D?

  ANGLE has OpenGL and OpenGL ES backends in addition to Direct3D, as well as partial Metal support. https://chromium.googlesource.com/angle/angle/+/master/README.md https://chromium.googlesource.com/angle/angle/+/master/READM...

  OpenGL or Vulkan as appropriate. AFAIK there's a Metal backend in development for macs but it's not finished yet.
