How Would You Visualize DOF in GL?

["Jeffrey Dates" <kungfukoi(at)gmail.com>]

heya,

So this keeps coming up during pre-vis.   How can a Pre-vis artist pre-vis
DOF in the viewport/GL Capture??

I am curious if this has really been discussed on the XSI side?

I've seen using the depth fog to attempt to do it.. but I feel it's just not
the right solution.

My thought would be ideally to have a way to have GL DOF..   sure it might
looks rough.. but it's for Pre-Vis purposes.  I mean Flash can do it. Games
can do it.. seems like those approaches might have a way to applying to our
GL viewports?

Just curious if this has been done very well?  Or if there are any thoughts
on this...

thanks,
