  1. I think I see the problem of having a GPU vendor...

    I think I see the problem of having a GPU vendor commiting to a OpenGL version. Say a vendor makes the statement "GPU X supports OpenGL Version 4". Could we say that, this GPU would also support...

    This is basically my problem. I assumed that it is fully hardware implementable without "newer" tessellation hardware. I thought it is some kind cure to the problem of not having ARB_draw_indirect on...

    For me, OpenGL 3.3 to OpenGL 4.0 was like the transition of DX10 to DX11 which was like the transition from non-tessellation hardware to tessellation hardware. So that API versions transition became...

    First of all. Thank you for your explanations!

    I am particularly talking about ARB_transform_feedback2.

    I totally commited to that extension because I thought it is within OpenGL 3.1-3.3...

    I though, Transform Feedback is OpenGL 3.1-3.3 domain!? It really bugs me that especially DrawTransformFeedback is in OpenGL 4 domain! I really do not understand why this is in OpenGL 4 Domain. Isn't...
  6. GL 4 Core Function Loading in Core 3.1+ Confusion

    Recently, I removed GLEW from my engine and implemented my own GL function loader. Well, I never really cared about it.
    During the refactoring step, I came to download the glcorearb.h file from the...

    Dark Photon, thanks for boiling it down!

    At least, I already assumed that the indirect technique in not available on GL 3.x hardware.

    To me, transform feedback seems a bit unfinished and there...

    I am more concerned about the availability of the "indirect technique" pertaining older gfx cards, i.e. pre GL 4.0 gpus. Since I am coding a game, I want to have it run on older hardware that has GL...

    Wait a minute! I looked ARB_draw_indirect up in the reg and it is written against GL 3.2. Doesnt this mean, it is only available in GL 4.0, or is it even available in GL 3.3? I cant get that version...
  10. Resize Buffer Object from Transform Feedback Result. GL3 < GL 3.3

    Hello GL Fellows.

    I need to glBufferData a buffer based on the result of a Transform Feedback.
    I do Iso-Surface extraction and the last step in the algo is the resize and copy of the result of...
