Blurry smooth edges of a mesh
i have a volumetric light scripts which creates a MESH in 2d space and the result looks like this: 
and i want to add the edge effect like blur+glow like in this one 
i used the fragment shader to achieve the decrease of radial luminance but i failed to access the adjacent pixels and change the values of them.Well i know that i must access the pixels by using TexelSize offset to get adjacent pixels but i only know how to get color values of them not to change the actual color.
