<p>Hi, <br>
</p>
<p> It is a GLSL extension, the ray tracing functions use some input
data (like the acceleration structure) that can only be
constructed and uploaded using the vk API.</p>

Well, I was wondering if there was an OpenGL RTX API
anywhere, but it doesn't seem there is.

<div>Vulkan would appear to be the way to go for the future,
but since that's not ready for the oven yet (don't even
have all the mise en place), it might be we just have to
make a utility library to shovel OSG data into OptiX and
let it do the work for now. There's always going to have
to be some kind of bridge from OSG to either Vulkan or
something else if no OpenGL support extension ever
appears.</div>
