The OpenGL Superbible forth edition has a chapter about HDR rendering
which explanations how you can make bright spots glow (page 633).
Basically, you render your scene into an FBO with two textures
attached and a fragment shader that only writes the bright parts into
the second texture, then you generate mipmaps from that texture and
apply a 5x5 gaussian kernel and you overlay that texture for display
on your normal scene.
