    Re: OpenGL 3 Updates

    Can we at least have a hint on whether it:

    Uses immutable state objects for render state switching and lpDrawArrays for geometry,
    OR still uses display lists for either,
    OR something completely...

    Re: OpenGL 3 Updates

    Yes, i should have been clearer.
    I just meant that someone starting to learn OpenGL should stay away from tutorials and and examples that use PBO's, and just use FBO's.
    PBO's do have there uses,...

    Re: OpenGL 3 Updates

    OpenGL could never be a sinking ship, it is supported by nearly every operating system and in most cases it is the primary 3D graphics API.
    The ES version is becoming more and more widely supported...

    Re: OpenGL 3 Updates

    Getting back to OpenGL3 for a moment, the siggraph 2008 schedule implies that the OpenGL3.0 Specification will be released Wednesday, 13 August at 6:00pm (California time).
    But nobody seems to be...

    For those of us who live 10,000km away and cant make it to the BOF,
    can we please get downloadable audio files of the presentations, as well as the slides,...

    Re: OpenGL 3 Updates

    This idea could also be extended to LOD textures.
    At the moment i do LOD MipMaps by keeping the current texture MipMap in RAM so that when the object using that texture comes twice as close to the...

    Re: OpenGL 3 Updates

    The good news is that pipeline 006 is due out, (Q4 2007)
    so they will be able to give us an update in pipeline 005,
    release OpenGL3,
    and then use oo6 to tell us all about the release. :D

    Re: OpenGL 3 Updates

    Yes, perhaps we should get back to "Things we would like explained in the next Pipeline newsletter".

    It must turn up soon, after all its the "Summer" edition and its going to be 35C (95F) all...

    Re: OpenGL 3 Updates

    Just use whatever is appropriate for the task, i use a combination of languages, ObjectPascal for most of the procedural stuff, a logical language for AI, with a few small assembly routines thrown in...

    Re: OpenGL 3 Updates

    The ObjectPascal "interface" behaves as a separate object inside of the real object, and begins with a VMT pointer just like a normal object.
    The code in the client exe that calls the method is...

    Re: OpenGL 3 Updates

    Yes, i was assuming an x86_32 driver in my examples, the x86_64 needs a completely different driver and compiler anyway so using a 64-bit pointer instead is not a problem.
    The spec could just say...

    Re: OpenGL 3 Updates

    Passing in registers is the "Default" behaviour, but any calling convention can be specified.
    In my examples i should have used "virtual; stdcall; abstract;" so the calling convention matches...

    Re: OpenGL 3 Updates

    Object pascal can do this in most cases;
    If i was statically linking to a DLL i could do:
    procedure glTexParameter( Target: enumTextureTarget, PName: enumTextureFilter, Filter: enumTextureFilter...

    Re: OpenGL 3 Updates

    What i most want to see in Pipeline 005 is a discussion on how best to set-up a multi-threaded application for OpenGL 3.

    eg. Say that i want to generate a shadow map and do a z-only pass from the...
