title: Inner and Outer Glow Implementation using Opengl ES 3.0
body: <p>I want to implement inner and outer glow for a rendered 3D object. Here the glow is to be applied only on the 3D models who have glow enabled and not for the entire scene.</p>
  
  <p>There is one post in stackoverflow that talks about implementing it using modifying the mesh, which in my opinion is difficult and intensive.</p>
  
  <p>Was wondering if it can be achieved through multi-pass rendering? Something like a bloom effect thats applied to specific objects in the scene and only to the inner and outer boundaries.</p>
