title: Is there any decent OpenGL SceneGraph API/framework?
body: <p>I am new to OpenGL. </p>
  
  <p>Wondering if there is any good Scenegraph API/framework for OpenGL. </p>
  
  <p>At the moment I am using glut with a custom node based solution: I am setting children and siblings for each node the calling a traverse function. </p>
  
  <p>I'd like a more flexible solution when it comes to managing dynamic elements in the scene.</p>
