    Re: OpenGL 3 Updates

    I have to disagree with this because we recently reviewed a driver from one of the mainstream vendors and our testing showed significant regressions only in our D3D series of tests while the OpenGL...

    Re: OpenGL 3 Updates

    But don't forget that OpenGL ES was quickly followed by OpenGL SC which ADDED back immediate mode and other similar features. One reason for that was the requirement for a well defined,...

    Re: OpenGL 3 Updates

    Actually there was quite a bit known about Fahrenheit. Microsoft even shipped XSG 1.0 with quite a bit of documentation and sample code -- I even have the disks and manuals to prove it but there was...

    Re: OpenGL 3 Updates

    I wrote the problem (well, technically ector posed the problem) and the *problem* is exactly NOT (and never has been) a requirement for any specific feature. The *problem* is being forced to search...

    Re: OpenGL 3 Updates

    It is precisely knowledgable of need - the need to efficiently determine the most capable supported format without blindly testing a linear list of acceptable results. The algorithm clearly does NOT...

    Re: OpenGL 3 Updates

    You are correct. For yes/no values where order is not important, the total number of possible combinations is 2^n. However, you can't argue that eliminating one feature cuts the number of possible...

    Re: OpenGL 3 Updates

    So we continue to wait for an inefficient solution.

    FWIW, if I know that a particular filtering mode is not supported at all for a particular graphics card, why should I even bother attempting to...

    Re: OpenGL 3 Updates

    If I understand correctly, you first create a format object and then use that format object to bind to an image object. There is no guarantee that the bind will succeed either (e.g., supported...

    Re: OpenGL 3 Updates

    Being explicit does not imply efficiency.

    I don't know how many different options are available to the format creation request, but the total number of possible failures is N-factorial (n!). A...

    Re: OpenGL 3 Updates

    Nonsense. It's much more flexible.

    By taking fully formed formats and returning yes/no, you have the ability to forbid things that are not easily quantifiable.[/QUOTE]
