<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">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

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
href="http://on-demand.gputechconf.com/gtc/2012/presentations/S0319-Advanced-Driver-Assistance-System-Testing-Using-OptiX.pdf"
moz-do-not-send="true">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>

<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>
