    <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>
