title: What happened to OpenRT?
body: <p>I have been looking around for powerful raytracing interfaces and discovered references to OpenRT but can't seem to find it anywhere. Does it even still exist?</p>
  
  <p>If it is gone, what is the most used library for raytracing that is powerful enough for realtime rendering.</p>
  
  <p>My answer below is all I have managed to find.</p>
  
  <h2>Update</h2>
  
  <p>I have continued my search and only seem to find OpenRL as it supports most of what I need. However I may end up writing my own wrapper or engine that suits my needs as there seems to be no mature solution. Thanks for the suggestions.</p>
