    Re: OpenGL 3 Updates

    Nevermind, you're right. We should pin all our hopes on the ARB and hardware vendors. They always come through.

    Re: OpenGL 3 Updates

    The key difference is that you currently require your OpenGL driver to come from one company as a gift at the time of their choosing with the features of their choosing. They in turn require all...

    Re: OpenGL 3 Updates

    I think the new deprecation model is a critically important move in the right direction. If the ARB will rev the API more than once over the next year to get rid of more cruft, fix selectors, and...

    We say "PA system" and "vacuum cleaner" in the US. :)

    Re: OpenGL 3 Updates

    OpenGL is and should remain a graphics hardware abstraction. What that abstraction should look like changes as hardware evolves. If the hardware becomes more flexible (i.e. with shaders), the...

    Re: OpenGL 3 Updates

    I don't have any problem with GLSL's shading language other than that it is specific to GL.

    The GLSL runtime API is way more indirect than it needs to be for high performance use. I think the...

    Re: OpenGL 3 Updates

    Having and retaining a legacy installed base may be the primary reason that OpenGL is still around today. Certainly it is one of the very important reasons. Blaming OpenGL's woes on the burden of...

    Re: OpenGL 3 Updates

    I dunno, working at id, I can now be a non-partisan OpenGL supporter.

    There are still a *lot* of people NVIDIA that care about OpenGL, and it's hard to argue with how up-to-date their OpenGL...

    Unfortunately, I don't think anybody that knows what's going on is free to discuss it outside Khronos.

    I realize this is frustrating and that information was flowing until it abruptly ceased...

    Re: OpenGL 3 Updates

    My preference at this point would be to see the major glaring problems in OpenGL efficiency addressed through limited scope EXT or vendor extensions via collaboration among a small number of IHVs and...

    Re: OpenGL 3 Updates

    I work at id, and we use OpenGL on Windows, but the API-specific part of the renderer is pretty easily encapsulated to support consoles in their native APIs.

    Re: OpenGL 3 Updates

    It's a tricky balance, I think. The other approach is to provide intimate hardware knowledge to software developers.

    Traditionally CPU vendors have had to take this route while GPU vendors have...

    Re: OpenGL 3 Updates

    NV3x supported neither blending or filtering of fp16 surfaces.

    NV4x was the first architecture that did, and it supported both, but without MSAA for the render targets.
