    Phoronix: OpenGL Transform Feedback For LLVMpipe

    An initial patch for review has been published by David Airlie that implements OpenGL Transform Feedback support for the LLVMpipe driver...

    Xeon Phi LLVMpipe benchmark

    I would really like to see a benchmark of the Xeon Phi on LLVMpipe
    http://www.anandtech.com/show/6451/4...=False&cPage=1
    The original Intel Larabee would have had a DirectX translation layer and this project could be seen as an OpenGL version of it.
    Just loading a distro with Gnome 3 running on LLVMpipe or benchmarking some ioq3 and iodoom3 games would be VERY interesting.

      From the first Google result for "transform feedback" (http://www.opengl.org/wiki/Transform_Feedback)
      Transform Feedback is the process of altering the rendering pipeline so that primitives processed by a Vertex Shader and optionally a Geometry Shader will be written to buffer objects. This allows one to preserve the post-transform rendering state of an object and resubmit this data multiple times.
      From the article:
      OpenGL Transform Feedback adds in the capability of altering the rendering pipeline to allow for primitives processed by Vertex/Geometry Shaders to be written to buffer objects. By writing it to buffer objects, the post-transform render state of an object can be saved so that it can be re-submitted multiple times.

        From the article:
        So? He quoted something from opengl.org. I'm confused - isn't it good that Michael posted an accurate description of what transform feedback is rather then expressing it in his own words and possibly misinterpreting if he's not an expert on the subject?

          If you quote something you should/have to mention the source of the quote.
