sunshine effects

i just wanted to ask you experienced OGL guys for a method of creating a sunbeam effect ,which can be seen in several games.
the light should kind of reflect in the “camera”,you know what i mean?
i thought of drawing 5,6 quads with flare-like textures and blending them, but i think about the general way to do this…
maybe you guys know the way how it is implemented in such games.

or maybe you’ve got some code for me…
