    Rework Chapter 14?

    I've asked how fragments, pixels, samples etc. relate to eachother. Notwithstanding, I'm positive that Chapter 14 can not be understood.

    Chapter 14 starts with stating that the window coordinates...
  2. Precision specification for coordinates and interpolated values

    The specification makes no statement regarding in which precision, say, device coordinates and window coordinates are calculated from clip coordinates. We have precision specifications for the clip...
  3. Relation between type, format, internal format, base internal format

    One would think that in order to work with textures, one needs notion of exactly two formats: The format of the texture (what is stored) and the format of what is provided (and is converted to the...
  4. A precise definition of fragments, samples, pixels and multisampling?

    Hello, I've read the specification multiple times fully, and albeit it (and the extension specs) may contain the information I need formally, I haven't been able to grasp the concepts of fragments,...

    11.2.2 What are the generated primitives, what is tesselated - It remains completely unspecified where the notion of "triangles" or "edges" comes from. Compared to primitives like, say, triangle...

    14.3.1 Multisampling - I find the whole beginning of the chapter incomprehensible. Even if you know how MSAA works, after reading it you're likely as confused as not to know it any more. The original...

    10.5 Indirect drawing - Bug 1082 - The description of indirect drawing doesn't give the slightest clue as to where the data are taken from, it should reference 10.3.10 for clarity or, better, 10.3.10...

    8.1 Textures - The introduction to this section leaves it largely unclear what exactly is the relation between "Texture Units" and "Texture Objects". I understand that things are the way they are...

    4.4 Collection of "improvable" wordings

    Hello, a while ago I stated that I find the specification unclear in certain passages but I wouldn't give a concise description of what exactly I find unclear as a whole. I still can't, but I figured...

    Please put a bit more thought into your statements. Obviously, this is not the same, you're just calling it that. "Opinion" and "speculation" are not the same thing. Let's say I take my wife to a...

    I'm actually delighted by your comment. Opposed to other people whose name I don't need to mention, you're absolutely capable of formulating clear, coherent counter arguments. Refreshingly, they are...

    It sure is. Why would anyone want to do that? Luckily, I don't want to ramble and I do pursue a purpose (if, for just a second you had thought that this wasn't so, you clearly should not have replied...
  13. And why is that? Why are vague complaints which...

    And why is that? Why are vague complaints which are supposed to provoke - even if just a little - reconsideration not worth paying attention to? I find this attitude unworthy of any critically...
  14. There is yet another thing I'd like to add with...

    There is yet another thing I'd like to add with regard to foward references. It is not occurence of forward references alone, that takes from clarity. It is particularly the way they are made:...

    You keep excusing poor wording and incomprehensibility by the need for being exact. By your own words, something which is understandably written cannot possibly be a specification because "a...

    You mistook my intend, which was not to silence you, but to warn you that any further arguments against those very specific examples will go ignored by me (thus, "out of respect").

    To save myself the effort. If I were to analyze the hundreds (yes) of inconsistencies, redundancies and generally ill-worded parts of the spec, I might aswell rewrite it. Also, as is vividly...
  18. To the authors: Please try to bit a more consistent

    I find myself repeatedly frustrated by ambiguous wording in the specification. I know the specification practically by heart,
    but even that doesn't help at times when the terms are becoming just too...

  20. Distinction between (default UB) uniform locations and uniform indices

    Why is there additional notion of uniform locations and why does the API not use the uniform index of the uniforms
    in the default UB to address them - which would then be consistent for both the...

    Layout specification in GLSL

    I've been welcomed with quite a lot of ignorance on the subject of "questioning the API" on the OpenGL IRC channels,
    I hope the attitude is a bit better on the forums. Instead of filing a bug,...

    Right, you just see the content of one of those frames, lacking the left "nav bar". I guess google site search is a way
    arround this problem then, thanks for the idea! No less, it would be good if...

    It would be much appreciated if you could reduce the enormous top frame in the GL Reference Pages. I often browse the
