    March'04 meeting notes

    Nobody posted this...
    So, finally, we will get GL2 and the feature list is complete. No ubber buffer included but also no word from EXT_render_target...

    And the markting group seems to be on the move...

    Commnents?

    Just to clarify... when they say that feature set will be included in OpenGL 2.0, does that mean those features will be included as extensions, or will they be included as core features?

    But ATI_draw_buffers will be included so I think there will be an extension like EXT_render_target. Does anyone know something more about this issue?

    AFAIK as core features
    There is a theory which states that if ever anybody discovers exactly what the Universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarre and inexplicable.

    There is another theory which states that this has already happened...

    Unfinished extensions, like EXT_render_target, aren't up for consideration for the core. And for good reason. Even an extension like VBO needs to live its life as an extension before absorption into the core, just to make sure that there are no kinks or unseen problems in it.

    Our dear friend John Stauffer from Apple (one of the 3 companies behind EXT_RT) did note that superbuffers was becoming complex, and that a different design could solve consumer's problems.

    Given this line "Instead, the WG will continue evolving its proposals and getting ISV feedback, allowing a chance for fully thought out alternate proposals to be brought forward.", it sounds like they decided to hold off on superbuffers until alternatives like EXT_RT can be brought forth and tested.

    BTW, nVidia, if you're listening (and you care), I'll buy your cards again if you give us this extension before ATi

    But ATI_draw_buffers will be included so I think there will be an extension like EXT_render_target.
    Considering that a vote wasn't taken at this meeting on it, I doubt that it (EXT_RT) will be included into the core. You have to remember, it is neither implemented, nor even finished yet.

    So what's thrown out from 1.*?

    And can we get implementations to fix polygon offset once and for all (sorry it's a pet peeve).

    Yes, I know. But does that mean that you have to use pbuffer for MRT or render to texture in OpenGL 2.0?? I really won't like that...

    What's the shader language metafile? Is it the equivalent of the effect files in d3d?

    From my complete ignorance, I would guess it's a binary format for glsl (ala bytecode).

    Hmmm interesting comment, in which way do implementations need to be fixed and how would you define the r factor for a floating point depth buffer?
