  1. Sticky: GL reference pages updated to Docbook 5 / HTML 5

    I've udpated the GL API and GLSL reference pages to Docbook 5 source and HTML5 output, so we can join the 2010s. They are now using MathJax for rendering equations on browsers that don't support...
  2. Sticky: I'm not sure what you mean by this. Enums that...

    I'm not sure what you mean by this. Enums that are bitmask values are tagged as such, e.g.

    <enums namespace="GL" group="AttribMask" type="bitmask">
    <enum value="0x00000001"...
  3. Sticky: Man pages are up

    The 4.4 updates to the man pages are live now, again thanks to Graham Sellers.

    There appears to be some weirdness with Javascript showing up at the beginning of the page, at least for me in...
  4. Sticky: The extension specifications are in a public part...

    The extension specifications are in a public part of Khronos' Subversion tree and you can see the history of public updates after a spec has been ratified. We're not going to publish the entire...
  5. Sticky: Generally speaking, a member company recommends...

    Generally speaking, a member company recommends them, the affected working group talks about it and and makes a recommendation to the Board of Promoters, and the BoP discusses and votes on the...
  6. Sticky: The GL tests share a codebase with the OpenGL ES...

    The GL tests share a codebase with the OpenGL ES 2/3 tests, which a bunch of stuff added for GL-specific features. So there are API coverage and functional tests, in some cases quite comprehensive...
  7. Sticky: No. Khronos can't require certification for...

    No. Khronos can't require certification for specifications that have already gone through ratification and have shipping implementations. Mandatory starts with GL 4.4 implementations. But some...
  8. Sticky: Bruce Merry (of Bugle fame, among other things)...

    Bruce Merry (of Bugle fame, among other things) wrote some scripts to detect possible command aliases and proposed a bunch for addition to gl.xml, which has been done now. There are a few more tweaks...

    FYI, I've put the .spec file parameter type & array length annotations into gl.xml. See here and feel free to provide feedback on the board, or patches in Bugzilla, if this helps address the concerns...
  10. Sticky: Since there was a good deal of demand for it,...

    Since there was a good deal of demand for it, I've added the parameter/return type and array length annotations from gl.spec and enum*.spec into gl.xml. This required some schema additions, and...

    I believe all of these have been addressed either by fixes to the extension specs, or fixes made in the old .spec files over time and now in the new XML spec files, with unlikely-to-be-changed...

    GetIntegerv is an interesting example because it can be passed a pointer to a scalar or to an array, depending on the state being queried. I'd think depending on the language, if you were returning a...

    Alfonse captured a bunch of the things I'd have said had I been online earlier, but here are a few additional comments.

    The goal of doing this wasn't to deprive people of things they're used to,...
  14. Sticky: The "actual documentation" is more complete (and...

    The "actual documentation" is more complete (and prettier) now: see PDF
  15. Sticky: New XML-based API Registry released

    The old gl.spec & related files are being retired, replaced by an XML-based description of the GL, GLX, WGL, GL ES, and EGL APIs as has been promised since slightly before the Dark Ages. The XML...
  16. Re: Man pages source available in Khronos Subversion

    We've opened up the directories containing GLSL (manglsl/) and common utility files (mancommon/) for anonymous SVN access as well - sorry for the oversight. The first post in this thread has been...
  17. Re: Trying to understand where EGL fits in the stack

    The EGL context creation API has functionality defined for both GL and ES contexts, but most implementations of EGL exist on mobile devices where only OpenGL ES is available. There is an EGL (1.1, I...

    Re: Official feedback on OpenGL 3.2 thread

    So maybe a baseball cap with the quick ref guide printed on it? :-)
  19. Re: Draft released for feedback

    Yes. You cannot expect that the static entry points for anything in glext.h will be defined in the GL link library, in which case there's no utility in defining a bunch of prototypes for functions...

    Re: Official feedback on OpenGL 3.2 thread

    You can do that, but as previously noted, nothing is deprecated from the compatibility profile, so a forward-compatible compatibility profile is exactly the same thing as a non-FC CP :-)

    I would...

    Re: Official feedback on OpenGL 3.2 thread

    They overlap but the use cases are very different. The FC context is really only intended as a futureproofing aid for developers, along the lines of the (otherwise so-far mythical) "debug context"....

    Re: Official feedback on OpenGL 3.2 thread

    To speak somewhat in our own defense, the GL and GLSL specs are huge, complex documents that go through many, many revisions during the process of creating a new version. John and I try to keep the...

    Re: Official feedback on OpenGL 3.2 thread

    Well, we kinda had to introduce an enabling mechanism to select the profile, once we introduced profiles. If you don't specify a profile or version or context flags in the attribute list, then...

    Re: Official feedback on OpenGL 3.2 thread

    OK, I understand now. I think both Sun and Apple have done vendor extensions along these lines, and we have sometimes discussed it as a future use case in the ARB. If we do something like this in a...

    Re: Official feedback on OpenGL 3.2 thread

    We folded the profile extension into the same documents as the original create_context extensions, largely because it was necessary to get them out on time for SIGGRAPH, for arcane reasons involving...
