Inner and Outer Glow Implementation using Opengl ES 3.0
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.
There is one post in stackoverflow that talks about implementing it using modifying the mesh, which in my opinion is difficult and intensive.
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.
Is this possible to do with OpenGL-ES? Im trying to make a quite simple 3D game in android with the use of OpenGL-ES. Now im stuck on the part where i think that using a ray to get the coordinates of
