title: Bind already existing cudaTextureObject to texture in OpenSceneGraph(OpenGL) for rendering
body: <p>I have a <code>cudaTextureObject</code> (2D) which is the result of a chain of signal processing kernels. 
  Now I would like to display this <code>cudaTextureObject</code> in our viewer with OpenSceneGraph.</p>
  
  <p>All solutions for OpenGl interop with CUDA I found so far need to create a OpenGL texture first and then register this texture resource with CUDA, so that the resulting resource can be manipulated in kernels. For example described here: <a href="https://stackoverflow.com/questions/19244191/cuda-opengl-interop-draw-to-opengl-texture-with-cuda">CUDA/OpenGL interop, draw to OpenGL texture with CUDA</a></p>
  
  <p>Is there a way in which I can just render the already existing cudaTextureObject (with its buffer) without copying it into a texture created by OpenSceneGraph (OpenGL)?</p>
