    <p>Hi Chris,</p>
    <p>if you are looking for raytracing osg scenes in general and not
      OptiX specifically, you could also have a look at <a href="https://github.com/szellmann/visionaray" target="_blank">https://github.com/szellmann/visionaray</a><br>
      There is a visionaray plugin for OpenCOVER which is our
      OpenSceneGraph based renderer. You find it here: <a href="https://github.com/hlrs-vis/covise" target="_blank">https://github.com/hlrs-vis/covise</a></p>

      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>

          While looking into using Nvidia RTX ray tracing of an OSG
          scene, I came across this document from 2012:
          <div><a href="http://on-demand.gputechconf.com/gtc/2012/presentations/S0319-Advanced-Driver-Assistance-System-Testing-Using-OptiX.pdf" target="_blank">http://on-demand.gputechconf.com/gtc/2012/presentations/S0319-Advanced-Driver-Assistance-System-Testing-Using-OptiX.pdf</a> </div>
          <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>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>
