    Hi Chris,<br>
    <br>
    I am looking through old mail and saw your questions. I have seen
    the code and as far as I can remember it was not used for rendering.
    It was not open source.<br>
    <br>
    Send me a PM for more details if you like.<br>
    <br>
    Cheers<br>
    Raymond<br>

        While looking into using Nvidia RTX ray tracing of an OSG scene,
        I came across this document from 2012:
        <div><a

        <div><br>
        </div>
        <div>It discusses using a plugin to convert an OSG scene to an
          OptiX scene, which is then rendered in OptiX.</div>
        <div><br>
        </div>
        <div>Has anyone ever seen or used this code? Was it open source?
          It may be dated, but it would be a starting point for new
          work.<br>
        </div>
        <div><br>
        </div>
        <div>With AMD getting into the ray tracing game, it would be
          nice to have a way to portably ray trace scenes on either
          NVidia or AMD (or Intel) GPUs, but I don't see anything
          stepping into that space yet. I saw the beginning of a Vulkan
          ray tracing library: </div>
